पद्य-विश्लेषण :

कविता का नाम – चाँदनी रात
कविता की विधा – खंडकाव्य
पसंदीदा पंक्ति – चारू चंद्र की चंचल किरणें खेल रही हैं जल-थल में। स्वच्छ चाँदनी बिछी हुई है अवनि और अंबर तल में।

पसंदीदा होने का कारण –
उपर्युक्त पंक्ति मेरी पसंदीदा पंक्ति है क्योंकि उसमें ‘च’ वर्ष की बार-बार पुनरावृत्ति होने से अनुमास अलंकार की छटा दिखलाई दे रही है। इस कारण कविता के सौंदर्य में वृद्धि हो गई है।

कविता से प्राप्त संदेश या प्रेरणा –
प्रस्तुत कविता से प्रेरणा यह मिलती है कि व्यक्ति को चाँदनी रात की तरह अपना जीवन सुंदर बनाना चाहिए। मनुष्य को प्रकृति के प्रति कृतज्ञ रहना चाहिए। प्रकृति मनुष्य के जीवन को शक्ति एवं आनंद प्रदान करती है। अत: उसे प्रकृति के साथ खिलवाड़ नहीं करना चाहिए। प्रकृति के संतुलन को बनाए रखने के लिए व्यक्ति को पेड़ लगाने चाहिए।

चाँदनी रात Summary in Hindi

कवि-परिचय:

जीवन-परिचय: मैथिलीशरण गुप्त जी खड़ी बोली के महत्त्वपूर्ण कवि हैं। इनका जन्म उत्तर प्रदेश में झाँसी जिले के चिरगाँव में हुआ। 12 वर्ष की अवस्था में उन्होंने ब्रजभाषा में कविता की रचना आरंभ की। उनकी रचनाएँ पवित्रता, नैतिकता, मानवीय संवेदनाओं और विशेषकर नारी के प्रति करुणा की भावना से ओतप्रोत हैं। उनकी रचनाओं से प्रसन्न होकर गाँधी जी ने उन्हें ‘राष्ट्रकवि’ की उपाधि दी। 12 दिसंबर 1964 ई. को दिल का दौरा पड़ने के कारण इनका निधन हो गया।
प्रमुख कृतियाँ: महाकाव्य – ‘साकेत’, खंडकाव्य – ‘यशोधरा’, ‘जयद्रथ वध’, ‘पंचवटी’, ‘भारत-भारती’, नाटक – ‘रंग में भंग’, ‘राजा-प्रजा’ आदि।

पद्य-परिचय:

खंडकाव्य: खंडकाव्य में मानव जीवन की किसी एक ही घटना की प्रधानता होती है। प्रासंगिक कथाओं को इसमें स्थान नहीं मिलता।
प्रस्तावना: प्रस्तुत कविता ‘चाँदनी रात’ पंचवटी खंडकाव्य से ली गई है। कवि मैथिलीशरण गुप्त जी ने इस कविता में प्रकृति की छटा का सुंदर रूप बड़े ही माधुर्य के साथ अभिव्यंजित किया है तथा चाँदनी रात का मनोहारी वर्णन सुंदर शब्दों में चित्रित किया है।

सारांश:

कवि चाँदनी रात का वर्णन करते हुए कहते हैं कि चंद्रमा की किरणें जल और थल में फैली हुई हैं। पृथ्वी से लेकर आकाश तक सर्वत्र चाँदनी बिछी हुई है। पूरी प्रकृति चाँदनी में सराबोर है। रात सन्नाटे में डूबी हुई है। वायु स्वच्छंद होकर मंद-मंद बह रही है। सभी दिशाओं में आनंद ही आनंद व्याप्त है। नियति चुपचाप अपने कर्तव्यों का पालन कर रही है। ऐसे में पंचवटी की छटा बहुत ही निराली प्रतीत होती है। उसकी घनी छाया में पत्तों की एक सुंदर कुटिया बनी हुई है। इसके सामने स्वच्छ शिला के ऊपर धैर्यशाली, निडर मनवाला एक पुरुष बैठा हुआ है। यह वीर ऐसा दिखाई पड़ता है जैसे कामदेव योगी बनकर बैठा है।

1. Match the first column with appropriate entries in the second and third columns and remake the table.

2. Clarify the differences

A. Distance and displacement
Answer:

Distance	Displacement
(i) Distance is the length of the actual path travelled by an object. (ii) It is a scalar quantity. (iii) It is either equal to or greater than displacement. (iv) Distance travelled is always positive.	(i) Displacement is the minimum distance between the starting and finishing points. (ii) It is a vector quantity. (iii) It is either equal to or less than distance. (iv) Displacement may be positive or negative or zero.

B. Uniform and non-uniform motion.
Answer:

Uniform motion	Non-uniform motion
(i) If an object covers equal distances in equal intervals of time it is said to be in uniform motion. (ii) Distance – time graph for uniform motion is a straight line. (iii) In uniform motion, acceleration is zero.	(i) If an object moves unequal distances in equal intervals of time, its motion is said to be non­uniform. (ii) Distance – time graph for non-uniform motion is not a straight line. (iii) In non-uniform motion acceleration is non-zero.

3. Complete the following table.

4. Complete the sentences and explain them.

a. The minimum distance between the start and finish points of the motion of an object is called the ……….. of the object.
b. Deceleration is ………………………. acceleration
c. When an object is in uniform circular motion, its ………………………. changes at every point.
d. During collision ………………………. remains constant.
e. The working of a rocket depends on Newton’s ………………………. law of motion.

5. Give scientific reasons.

a. When an object falls freely to the ground, its acceleration is uniform.
Answer:

• When the body falls freely to the ground, there are equal changes in velocity of the body in equal intervals of time.
• Thus the acceleration of the body is constant, and it possesses uniform acceleration.

b. Even though the magnitudes of action force and reaction force are equal and their directions are opposite, their effects do not get cancelled.
Answer:

• Action and reaction forces act on different bodies.
• They don’t act on the same body, hence they cannot cancel each other’s effect.
• Hence, even though the magnitudes of action force and reaction force are equal, they do not cancel each other.

c. It is easier to stop a tennis ball as compared to a cricket ball, when both are traveling with the same velocity.
Answer:

• Momentum of an object depends on its mass as well as its velocity.
• Cricket ball is heavier than a tennis ball. Although they are thrown with the same velocity, cricket ball has more momentum than a tennis ball.
• The force required to stop a cricket ball is more than a tennis ball.
• Hence it is easier to stop a tennis ball than a cricket ball moving with same velocity.

d. The velocity of an object at rest is considered to be uniform.
Answer:

• When a body is at rest there is no change in velocity.
• A body with constant velocity is said to be in uniform motion.
• Hence, the state of rest is an example of uniform motion.

6. Take 5 examples from your surroundings and give an explanation based on Newton’s laws of motion.

7. Solve the following examples.

Answer the following in short:

Question 1.
Explain the three different ways to change the velocity.
Answer:
As velocity is related to speed and direction, it can be changed by :

• Changing the speed while keeping the direction constant.
• Changing direction while keeping speed constant.
• Changing both speed as well as direction of motion.

Question 2.
Explain what is positive, negative and zero acceleration.
Answer:

• Positive Acceleration: When the velocity of an object increases, the acceleration is positive. In this case, the acceleration is in the direction of velocity.
• Negative Acceleration: When the velocity of an object decreases with time, it has negative acceleration. Negative acceleration is also called deceleration. Its direction is opposite to the direction of velocity.
• Zero Acceleration: If the velocity of the object does not change with time, it has zero acceleration.

Question 3.
What inference do we draw from the velocity-time graph for a uniformly accelerated motion?
Answer:

• From velocity-time graph we can infer whether velocity changes by equal amounts in equal intervals of time or not.
• Thus, for all uniformly accelerated motion, the velocity – time graph is a straight line and slope of the line gives the acceleration.
• For non-uniformly accelerated motion, velocity-time graph can have any shape according to variation in velocity with respect to time.

Question 4.
State the three equations of motion and give the relationship explained by them.

Answer:

• Action and reaction are terms that express force.
• These forces act in pairs. One force cannot exist by itself.
• Action and reaction forces act simultaneously.
• Action and reaction forces act on different objects. They do not act on the same object and hence cannot cancel each other’s effect.

Question 6.
Explain recoil and recoil velocity. Derive its expression.
Answer:

• Let us consider the example of a bullet fired from a gun. When a bullet of mass nij is fired from a gun of mass m₂, its velocity becomes v₂, and its momentum becomes m^. Before firing the bullet, both the gun and the bullet are at rest. Hence, total initial momentum is zero.
• According to Newton’s third law of motion, the total final momentum also has to be zero. Thus, the forward-moving bullet causes the gun to move backward after firing.
• This backward motion of the gun is called its recoil. The velocity of recoil, v₂ is such that,

Question 1.
Newton’s third law of motion
Answer:
‘Every action force has an equal and opposite reaction force which acts simultaneously’.

• Action and reaction are terms that express force.
• These forces act in pairs. One force cannot exist by itself.
• Action and reaction forces act simultaneously.
• Action and reaction forces act on different objects. They do not act on the same object and hence cannot cancel each other’s effect.

Question 2.
Explain Newton’s second law of motion and derive the formula.
Answer:
Newton’s second law explains about change in momentum. It states that The rate of change of momentum is proportional to the applied force and the change of momentum occurs in the direction of the force.

Suppose an object of mass ‘m’ has an initial velocity ‘u. When a force ‘F’ is applied in direction of its velocity for time ‘t’, its velocity becomes ‘y’. Then, the total initial momentum of the body = ‘mu’. Its final momentum after time t = ‘mv’.

So, the rate of change of momentum

Hence by Newtons second la of motion, 4he rate of change of momentum is proportional to the applied force.
∴ ma ∝ F
∴ F ∝ ma
∴ F ∝ kma (k = Constant of proportionaLity and value is 1).
∴ F = ma

Let their initial momentum be m₁u₁ and m₂ u₂
Let their final momentum be m₁v₁ and m₂v₂

Total initial momentum = (m₁u₁ + m₂u₂)
Total final momentum = (m₁v₁ + m₂v₂)

If F₂ is the force that acts on object B,

i.e. The magnitude of total of total final momentum = the magnitude of total initial momentum

Complete the paragraph:

Question 1.
Moving Objects
Answer:
‘Distance’ is the length of the actual path travelled by an object in motion while going from one point to another, whereas displacement is the minimum distance between the starting and finishing points. The displacement that occurs in unit time is called velocity. The units of speed and velocity are the same. In the SI system, the unit is m/s while in the CGS system; it is cm/s. Speed is related to distance while velocity is related to the displacement. If the motion is along a straight line, the values of speed and velocity are the same, otherwise they can be different. The first scientist to measure speed as the distance /time was Galileo. The speed of sound in dry air is 343.2 m/s while the speed of light is about 3 x 108 m/s. The speed of revolution of the earth around the sun is about 29770 m/s.

Question 2.
Types of motion
Answer:
If an object covers unequal distances in equal time intervals, it is said to be moving with non-uniform speed. For example the motion of a vehicle being driven through heavy traffic. If an object covers equal distances in equal time intervals, it is said to be moving with uniform speed. The rate of change of velocity is called acceleration. If the velocity changes by equal amounts in equal time intervals, the object is said to be in uniform acceleration. If the velocity changes by unequal amounts in equal time intervals, the object are said to be non-uniform acceleration. The speed of the tip is constant, but the direction of its displacement and therefore, its velocity is constantly changing. As the tip is moving along a circular path, its motion is called uniform circular motion.

Question 3.
Newton’s laws and conservation of momentum
Answer:
An object continues to remain at rest or in a state of uniform motion along a straight line unless an external unbalanced force acts on it. The rate of change of momentum is proportional to the applied force and the change of momentum occurs in the direction of the force. Momentum has magnitude as well as direction. Its direction is the same as that of velocity. In SI system, the unit of momentum is kg m/s, while in CGS system, it is g cm/s. If an unbalanced force applied on an object causes a change in the velocity of the object, then it also causes a change in its momentum.

The force necessary to cause a change in the momentum of an object depends upon the rate of change of momentum. Every action force has an equal and opposite reaction force which acts simultaneously. As the mass of the gun is much higher than the mass of the bullet, the velocity of the gun is much smaller than the velocity of the bullet. The magnitude of the momentum of the bullet and that of the gun are equal and their directions are opposite. Thus, the total momentum is constant. Total momentum is also constant during the launch of a rocket.

Answer the following in detail:

Question 1.
What is speed? State its units and types. Explain instantaneous speed and average speed.
Answer:

The speed of a body is the distance travelled in unit time. The units of speed in CGS system is cm/s and in SI system is m/s.
There are two types of speed :

• • Uniform speed : When a body covers equal distance in equal intervals of time throughout its motion, it is said to have uniform speed.
  • Non-uniform or variable speed: When a body covers unequal distance in equal intervals of time it is said to have non-uniform speed.

The speed of the body at any instant is called instantaneous speed. Average speed is the ratio of total distance covered to total time taken.

Question 2.
What is velocity? State its units and types.
Answer:

The velocity of a body is the distance travelled by a body in a particular direction in unit time. Thus, rate of change of displacement is called velocity.

v = s/t
where: s = displacement; t = time taken; v = velocity
(MKS unit: m/s CGS unit: cm/s)
There are two types of velocities :

• • Uniform velocity: If there is equal displacement taking place in equal intervals of time, it is uniform velocity.
  • Non-uniform velocity or variable velocity: If there is unequal displacement in equal intervals of time, it is non-uniform velocity.

Question 3.
What is acceleration? State its units and types.
Answer:
(i) Acceleration is a rate of change in velocity. It is a vector quantity, \(a=\frac{v-u}{t}\)
where : v = final velocity; u = initial velocity;
a = acceleration
Units of acceleration in SI system is m/s2 and CGS system is cm/s2.

(ii) Types of acceleration: .
(a) Uniform acceleration : If the change in velocity is equal in equal intervals of time, the acceleration is uniform acceleration.
(b) Non-uniform acceleration : If the change in velocity is unequal in equal intervals of time, the acceleration is a non-uniform acceleration.

(iii) Kinds of acceleration:
Positive acceleration : When the velocity of an object goes on increasing, it is said to have Positive acceleration.
Negative acceleration : When the velocity of an object goes on decreasing, it is said to have negative acceleration or retardation or deceleration.
Zero acceleration : If the velocity of the object does not change with time, it has zero acceleration.

Question 4.
Explain Newton’s second law of motion and derive the formula.
Answer:
Newton’s second law explains about change in momentum. It states that ‘The rate of change of momentum is proportional to the applied force and the change of momentum occurs in the direction of the force.’

Suppose an object of mass’m’ has an initial velocity ‘u’. When a force ‘F’ is applied in the direction of its velocity for time’t’, its velocity becomes ‘v’. Then, the total initial momentum of the body = ‘mu’. Its final momentum after time t = ‘mv’.

So, the rate of change of momentum

Hence by Newton’s second law of motion, the rate of change of momentum is proportional to the applied force.
∴ ma ∝ F
∴ F ∝ ma
∴ F = kma (k = Constant of proportionality and value is 1).
∴ F = ma

Question 5.
State the law of conservation of momentum and derive the formula.
Answer:
(i) Let mass of objects A and B be and m₂ respectively
Let their initial velocity be m₁ and u₂
Let their final velocity be V₁ and v₂

(ii) We know,
P = mv
Let their initial momentum be m₁u₁ and m₂u₂
Let their final momentum be m₁v₁ and m₂v₂

(iii) Total initial momentum = (m₁u₁ + m₂u₂)
Total final momentum = (m₁v₁ + m₂v₂)

(iv) If F₂ is the force that acts on object B,

i.e. The magnitude of total final momentum = the magnitude of total initial momentum.

Question 6.
Obtain the equations of motion by graphical method:

(a) Equation for velocity-time relation.
Answer:
Velocity-time graph: shows the change in velocity with time of a uniformly accelerated object. The object starts from the point D in the graph with velocity v. Its velocity keeps increasing and after time t it reaches the point B on the graph.

The initial velocity of the object = u = OD

(b) Equation for displacement-time relation.
Answer:
Suppose that an object is in uniform acceleration ‘a’ and it has covered the distance ‘s’ within time’t’. From the graph the distance covered by the object during time’t’ is given by the area of quadrangle DOEB.

(c) Equation for displacement-velocity relation.
Answer:
We can determine the distance covered by the object in time t from the area of the quadrangle DOEB. DOEB is a trapezium. So we can use the formula for its area.

This is Newton’s third equation of motion.

Answer:
An object continues to remain at rest or in a state of uniform motion along a straight line unless an external unbalanced force acts on it.

(v) Which force is required to produce motion in an object?
Answer:
Unbalanced force is required to produce motion in an object.

2. Paragraph 2
constant velocity. If that velocity is zero, then the object remains at rest. If an external force is applied, the velocity will change because of the force. The second law explains how the velocity of an object changes when it is subjected to an external force. The law defines a force to be equal to changes in momentum (mass times velocity) per change in time. Newton also developed the calculus of mathematics, and the “changes” “expressed in j the second law are most accurately defined in differential forms. (Calculus can also be used to determine the velocity and location variations experienced by an object subjected to an external force.) For an object with a constant mass the second law states that the force F is the product of an objects mass and its acceleration a:
F = m * a
For an external applied force the change in velocity depends on the mass of the object.

A force will cause in velocity; and likewise, a change in velocity will generate a force. The equation works both ways.
The third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal force on object: A. Notice that the forces are exerted on different objects. The third law can be used to explain the generation of lift by a wing and the production of thrust by a jet engine

(i) A chalk kept on the table remains in the position of rest until moved by the teacher. Which law of motion is followed in this situation?
Answer:
Newton’s 1st law is followed in this situation e

(ii) What will happen to momentum if the mass and acceleration both are doubled?
Answer:
If the mass and acceleration both are doubled then the momentum will be increased four times

(iii) What will happen to momentum if the mass and acceleration both are halved?
Answer:
If the mass and acceleration both are doubled then the momentum will be decreased one four times

(iv) A moving stone filled truck collides with a moving car coming from opposite direction. Why is it observed that only the car is pushed backward?
Answer:
A stone filled truck as more mass than a car hence it has more momentum thus it is observed that only the car is pushed backward

(v) What will happen to the force if the jet engines do not produce enough thrust to push the aeroplane in mid-air?
Answer:
If the jet engines do not produce enough thrust to push the aeroplane in mid-air the force of aeroplane and resistance of air will become balanced thus putting the aeroplane at rest which will result in a crash.

2. Give geographical reasons.

(a) Buildings collapsed at the foothills of the Himalayas because of an earthquake. Before collapsing they were moving forward and backward.
Answer:

• The seismic waves can be divided into primary, secondary and surface waves.
• The primary waves are the first ones to reach the surface of the earth after the energy is emitted in the Earth’s interior.
• Subjected to a ‘P’ wave, particles in the rock move in the direction of waves to and fro and therefore, these waves are also called forward-backward waves.
• Thus, during an earthquake, the buildings at the foothills of the Himalayas moved forward and backward as they were first subjected to “P” waves.

(b) There is a difference in the formation of the Meghalaya Plateau and the Deccan Plateau.
Answer:

1. The Meghalaya plateau is formed due to slow movements (orogenic movements) whereas the Deccan Plateau is formed due to sudden movements (fissure volcano).
2. During the formation of the Meghalaya plateau, a part of the Earth’s crust in between two parallel faults was lifted forming a plateau whereas, the Deccan plateau was formed due to molten material coming out with the eruption spreading on both sides of the fissure.
3. Thus, there is a difference in the formation of the Meghalaya plateau and the Deccan plateau.

(c) Most of the volcanoes are found on the plate boundaries.
Answer:

• The plate boundaries are directly related to the areas of volcanoes.
• Most of the volcanoes are located on the plate boundaries.
• The part of the plate boundary which slides under the crust, results in the loss of material. Such boundaries are called plate consuming boundaries.
• In areas where new material (magma) is coming up onto the Earth’s crust, they are called plate creating boundaries.
• Both the processes result in earthquakes and volcanoes. Thus, most of the volcanoes are formed in the plate boundaries.

(d) The Barren Island is becoming conical in shape.
Answer:

• Barren island which was considered a dormant volcano has become active since February 2017.
• Mainly dust, smoke and mud are coming out of this eruption along with some lava.
• During eruption, the lava is spread around the mouth of this vent, when it comes out.
• As a result, a cone-shaped mountain starts forming.

Therefore Barren Island is becoming conical in shape.

(e) Volcanic eruptions can cause earthquakes.
Answer:

• Generally, the movements in the Earth’s interior occur in the upper layer of the mantle
• Tremendous energy is released by radioactive materials present here.
• This leads to a sudden movement in form of volcanic eruptions where hot solid, liquid and gaseous materials are forcefully thrown out from the mantle of the Earth, onto the surface of the Earth.
• This causes a lot of instability within the crust of the Earth which would also lead to the release of pressure in the form of seismic waves or tremors causing earthquakes.

5. Distinguish between

(a) Block Mountain and Fold Mountain
Answer:

Block Mountain	Fold Mountain
(i) When a part of the earth’s crust between two parallel faults is lifted a block mountain is formed.	(i) Because of the energy waves and pressure working towards each other, the layers of the soft rocks form folds leading to the formation of fold mountains.
(ii) Block mountains are formed due to tension.	(ii) Fold mountains are formed due to compression.
(iii) e.g. The Black forest mountains of Europe and the Meghalaya Plateau of India.	(iii) e.g. The Himalayas, the Aravalis, the Rockies, the Andes, the Alps

(b) Primary and Secondary Seismic Waves
Answer:

Primary Seismic Waves	Secondary Seismic waves
(i) Primary waves are the first one to reach the surface of the earth after the energy is emitted in the Earth’s interior.	(i) The waves which reach the Earth’s surface after the primary waves are called secondary waves.
(ii) Primary waves can travel through solid, liquid and gaseous medium.	(ii) Secondary waves can travel only through only solid medium.
(iii) While travelling through liquid medium, primary waves change their direction.	(iii) Secondary waves get absorbed as they enter the liquid medium.
(iv) The waves move to and fro in the direction of energy transfer.	(iv) These waves move up and down in the direction of energy transfer.

(c) Earthquakes and volcanoes
Answer:

Earthquakes	Volcanoes
(i) Earthquake is the movement of the Earth’s crust.	A volcano is an opening in the Earth’s crust from which hot solid, liquid and gaseous materials are thrown out from the mantle of.
(ii) Nothing is ejected out during an earthquake.	During a volcanic eruption, ash, water vapor, various types of poisonous and inflammable gases, hot molten magma etc. is ejected from the earth’s interior.

6. Answer in brief
(a) Give reasons why an earthquake occurs.
Answer:

• When the movements occur in the interior of the Earth, tremendous tension is created in the Earth’s crust.
• When the tension goes beyond limits, the energy is released in the form of waves.
• This results in the trembling of the earth’s surface, i.e. an earthquake occurs.

Following are the reasons for the occurrence of an earthquake:

• Moving of the plates
• Colliding of the plates
• Plates sliding one below the other
• Forming of fractures in rock layers, due to tension in the interior of the Earth.
• Occurring of volcanic eruption

(b) Which type of movements have led to the formation of the major fold mountains in the world?
Answer:

• Fold mountains are formed due to mountain-building (erogenic) movements.
• Energy is transferred from the interior of the Earth. Because of these energy waves and pressure working towards each other and in horizontal direction, the layers of the soft rocks form folds.
• If the pressure is very high, large scale folds are formed and their complexity increases.
• As a result, the surface of the Earth gets uplifted and fold mountains are formed.
• The Himalayas, the Aravalis, the Rockies, the Andes, the Alps are the major fold mountains of the world.

(c) How is the magnitude of the earthquake-related to the collapse of houses
Answer:

• Through a seismogram, a graph showing movement of seismic waves (seismograph) can be generated.
• After studying this graph, the magnitude of the earthquake is known.
• The magnitude of the earthquake is measured with the help of a richter scale.
• It is because of the primary waves that the buildings on the Earth’s surface move back and forth.
• The buildings on the Earth’s surface move up and down because of the secondary waves. These are more destructive than the T’ waves leading to collapse of buildings.

(d) What are the effects of earthquakes on the earth’s surface and human life?
Answer:
Following are the effects of earthquakes:

• Cracks/fractures develop on the ground.
• These causes landslides which leads to sliding of rocks.
• Sometimes the groundwater changes its course. For example, wells may get water, or may dry up.
• Some areas get uplifted while some may subside.
• Tsunamis are generated in oceans These waves can cause great loss of life and property in the coastal areas.
• In snow-covered areas, avalanches may occur.
• Buildings collapse and loss of life and property occurs.
• Transportation routes get disrupted.
• The communication system collapses.

(e) Explain the types of seismic waves.
Answer:
When the intension is released at the focus, the released energy travels in all directions. This energy comes towards the Earth’s surface in the form of waves. The seismic waves can be divided into primary, secondary and surface waves.
(i) Primary or ‘P’ waves:

• These waves are first to reach the surface of the Earth, after the energy is emitted in the Earth’s interior. They travel at a very fast speed from the focus of the earthquake in radial direction.
• The waves moves to and fro, therefore these waves are called forward-backward waves.
• These waves can travel through all the three states – liquid, solid and gaseous.
• While travelling through liquid medium, their direction gets changed. It is because of the primary waves that the buildings on the Earth’s surface move back and forth.

(ii) Secondary or ‘S’ waves :

• The waves which reach the Earth’s surface after I the primary waves are called secondary waves. :
• These waves also scatter in all directions from the focus of the earthquake.
• Their velocity is less than ’P’ waves.
• The particles lying in the way of these waves j move up and down in the direction of energy transfer.
• These waves can travel only through the solid medium and they get absorbed as they enter the liquid medium.
• The buildings on the Earth’s surface move up and down because of these waves. These are more destructive than ‘P waves.

(iii) Surface or ‘L’ waves :

• These waves are generated after the main ’P’ and ‘S’ waves reach the epicenter.
• They travel in the direction of the circumference of the Earth, along the crust and are highly destructive.

(f) Explain the types of volcanoes on the basis of the periodicity of eruption with examples.
Answer:
According to the periodicity of the volcanic eruptions, three types of volcanoes can be identified.
(i) Active Volcanoes –

• If the volcanic eruptions are regular even in the present times, then such volcanoes are called active volcanoes.
• E.g., Mt Fujiyama in Japan and Mt. Stromboli in the Mediterranean Sea.

(ii) Dormant Volcanoes –

• When a volcano has not erupted since long, but may become active suddenly is called a dormant volcano.
• E.g., Mt. Vesuvius in Italy, Mt. Katmai in Alaska and Barren Island, India.

(iii) Extinct volcanoes –

• Those volcanoes which have not erupted in the past since long and are not likely to erupt in the future are called extinct volcanoes.
• E.g., Mr. Kilimanjaro in Tanzania.

Answer:
Plate boundaries are directly related to areas of earthquakes and volcanoes. Most of the volcanoes are located on the plate boundaries. Similarly, the earthquake zones are also seen in the border areas.

Give geographical reasons:

Question 1.
The secondary earthquake waves are very destructive.
Answer:

• Due to secondary earthquake waves, the grains in the rocks move up and down, that is, perpendicular to the direction of the movement of the waves.
• Therefore, secondary waves are very destructive.

Answer in brief:

Question 1.
Explain the types of volcanoes on the basis of their type of eruption, with examples.
Answer:
On the basis of the type of eruption, volcanoes can be divided into two types.
(i) Central-type or conical volcano:

• During eruption, the molten magma comes out through a pipe-like vent from inside the Earth’s surface. The lava spreads around the mouth of this vent, when it comes out.
•  Asa result, cone-shaped mountains start forming and conical volcanic mountains are formed.
• Mt. Fujiyama in Japan and Mt. Kilimanjaro in Tanzania are examples of central-type volcanoes and conical mountains.

(ii) Fissure-type volcano:

• During eruption, when the magma comes out not from a single vent, but from many cracks (fissures), it is called fissure-type volcanic eruption.
• The molten material coming out with the eruption spreads on both the sides of the fissure. ;
• As a result, volcanic plateaus are formed.
• The Deccan Plateau of India has also been formed due to such a type of volcanic eruption.

Question 2.
Describe the changes that take place on the surface of the Earth, due to the movements taking place in the interior of the Earth.
Answer:
The changes taking place on the surface of the Earth, due to the internal movements of the Earth are as follows:

1. The soft rocks are subjected to pressure due to the energy released in the interior of the Earth. This leads to the development of folds.
2. If the pressure is very high, large scale folds are formed, and their complexity increases. As a result, the surface of the Earth gets uplifted and fold mountains are formed.
3. When the energy waves move away from each other, tension in the rock is developed. In hard rocks, the tension leads to faulting, when a portion between two parallel faults is raised up, block mountains are created.
4. Sometimes, when the portion between two parallel faults subsides, a rift valley is created.
5. Sometimes, an extensive portion is raised to form a continent or an extensive plateau.

Question 3.
How are continents and extensive plateaus formed?
Answer:

• The epeirogenic movements are responsible for the formation of continents.
• Slow movements occur towards the centre or from the Earth’s centre towards the Earth’s crust.
• Because of these movements, a vast part of the Earth’s crust is uplifted or gets subsided.
• When the part of the Earth’s crust is uplifted above the sea mean level, continents are formed.
• Therefore, these movements are called continent-building movements.
• Extensive plateaus can also be formed because of such movements.

Question 4.
What are the effects of volcanoes?
Answer:
The following are the effects of volcanoes:

• Loss of life and property.
• Sometimes tsunamis get generated due to volcanic eruptions occurring below ocean floors.
• Dust, smoke, ash, gases, water vapour, etc. remain in the atmosphere for a long time.
• This may create an imbalance in the environment.
• Land may become fertile due to volcanic ash.
• Many minerals are found near the earth’s surface because of lava.
• New land is formed due to volcanic eruption or at times, an island may even disappear.
• Lakes are formed at the mouth of the craters of dead volcanoes when rainwater accumulates in them.

Question 5.
Explain the process of the formation of Block mountains.
Answer:

• Because of internal movements, horizontal waves moving away from each other are formed.
• This causes tension on the layers of rocks leading to the formation of fractures in the rocks called as faults.
• Similarly, waves coming towards each other in hard rocks also form faults due to compression.
• When a part of the earth’s crust in between two parallel faults is lifted, it looks like a block. Such a landform is called as a Block mountain.
  

Question 6.
Explain the process of formation of Rift valley.
Answer:

• When horizontal movements on the earth’s surface act in opposite direction, it causes tension on the rocks in the earth’s crust.
• When tension increases, fractures develop in the rocks leading to the formation of faults.
• Consequently, rocks on both the ends slide and the continuity in the layers of rocks is not found.
• Sometimes, two fractures develop side-by-side in the earth’s crust and land in between the two fractures subsides. This subsided deep part is called the rift valley.

Question 1.
Write a few lines about what Mathilde had and what she dreamt about.

4. Write what you think about the following thoughts and actions of Mathilde.

Question a.
Mathilde was beautiful, and so she wanted to marry an aristocrat.
Answer:
She was not wrong to think so, because I think every woman, beautiful or not, wants to marry a person, who has a good position and wealth.

Question b.
Mathilde was sad because she did not get any luxuries.
Answer:
Her thinking was not correct. Not every one gets a luxurious life. She should have managed in whatever they were earning and lived a simple but happy life.

Question c.
Mathilde felt that her house was shabby and poorly furnished.
Answer:
Her feelings are wrong because it depends on the people who live in the house to keep the house clean, tidy and beautiful with whatever furniture, things they have got.

Question d.
Mathilde wanted other people to envy her.
Answer:
Mathilde’s thought was wrong because happiness does not depend on making the people envy you. She wished that people would have admired her if she had rich dresses and jewels.

Question e.
Mathilde was not happy to see the invitation.
Answer:
Mathilde did not care about the importance of the invitation, her husband had received. She was thinking only about the dress she would wear there.

Question f.
Mathilde wanted a new dress for herself.
Answer:
Mathilde wanted a new dress for herself only to selfishly corner her husband for extorting money from him to buy a new dress. Her thought was silly and unreasonable.

Question g.
Mathilde borrowed a diamond necklace from her friend and wore it to the party.
Answer:
Borrowing a diamond necklace was not a dire need of Mathilde. She could have used flowers instead; but she wanted another woman’s necklace to make a show of her beauty. She did not understand that borrowing is begging.

Question h.
Mathilde lost her necklace.
Answer:
Mathilde was so overwhelmed and captivated by her success that she was not aware of her responsibility of safe-keeping the borrowed necklace carefully. She lost it only because of her carelessness.

5. Prepare a formal invitation using the following format:

Question 1.
Complete the following table.

3. Write what you think about the following thoughts and actions of Mathilde

Question a.
Mathilde was shocked despaired over the loss of her necklace
Answer:
I think her reaction to the loss of her necklace was natural. But she herself was responsible for the tragedy. Her stubborn behaviour is to be blamed for the loss.

Question b.
Mathilde wrote a note to her friend as dictated by her husband.
Answer:
The couple couldn’t find the lost necklace even after a long search. They expected to find it some day. For that they needed some more time and Mathilde was compelled to write the false letter to I her friend. Her action of telling lies and betraying her friend was immoral and ridiculous.

Question c.
Mathilde and her husband decided to replace the necklace.
Answer:
I think that their decision of replacing the necklace was immature and insincere. Instead, they should have clearly and openly told Madame Forestier about the incident. It could have saved them from the horrible life they had to face and the dreadful debt they had to pay.

Question d.
Mathilde returned the diamond necklace to her friend
Answer:
I think, it was her moral responsibility to return the borrowed diamond necklace immediately after the party day but she delayed. She did so to hide the fact that she had lost the diamond necklace. Her negligence made her to make one more wrong.

Question e.
Mathilde did not tell her friend about the loss and replacement.
Answer:
It was another big mistake she committed. It was her thoughtless action. Had she told her friend about the loss of the necklace, further ruinous incidents wouldn’t have occurred and the remedy for the problem would have been very simple and easy.

Question f.
Mathilde worked very very hard to pay the debt.
Answer:
Mathilde’s action shows that she was a completely transformed woman. She had changed her attitude towards her lifestyle. She forgot her dreams of living a luxurious life. She worked hard and saved money for repaying the debt. She felt duty-bound for coming out of the devastating situation, she was responsible for.

Question g.
Mathilde and her husband paid off the debt in ten years.
Answer:
The income of Mathilde’s husband was meagre. So both of them worked very hard for ten long years to save money for repaying the debt. They curtailed their needs severely, her husband worked extra to ease the burden of debt. Somehow they faced the woes together bravely and sincerely.

Question 1.
Imagine what must have happened after Mathilde’s friend discovered that the diamonds were real. Do you think she would return it to Mathilde? Would that make Mathilde happy?

Mathilde’s friend was rich but a kind-hearted and generous woman. She knew that Mathilde had to face many miseries for ten years. I think she would return the necklace to Mathilde. Mathilde would be happy to find some relief after ruinous sufferings.

Question 1.

Answer:
When I receive an invitation for a party, I feel very happy because we get to meet our friends and relatives at the party and we can spend some time rejoicing. We also get to eat tasty food in the party.

Question 2.
Was Mathilde’s husband a considerate person? How do you know that?
Answer:
Mathilde’s husband was really a very considerate person. Though his wife was obstinate and stubborn, he tried to fulfill all her unreasonable wishes. He sacrificed his own hunting joy and gave his savings to please Mathilde. This shows that he was a very considerate person.

Question 3.
Mathilde asked her friend, “Would you lend me this, just this?”
Why, do you think, did Mathilde say ‘just this’?
Answer:
I think, Mathilde was fully satisfied with the diamond necklace she got. It looked beautiful in her neck as she had desired. So she did not want anything else except that diamond necklace and so she insisted to lend her that and only that necklace.

Question 4.
Why, do you think, did Mathilde not notice the loss of her necklace?
Answer:
I think, she was thinking only about the triumph of her beauty and success in the party. She had lost her attention towards her necklace. Secondly, they left the party early in the morning, could not find a cab and had to walk for a long distance. This also must be the cause of the distraction.

Question 5.
Do you think, the arrangement made by Mr Loisel with the jeweller, was fair? Give your reason:
Answer:
Yes I think the arrangement was fair. According to the arrangement the jeweller would take the necklace back for thirty-four thousand if the other (the lost) necklace was found before the end of February. It would help them to get some more time to find the necklace and again they would ; be losing only two thousand francs instead of thirty- 5 six thousand.

Question 6.
Why does Madame Forestier speak coldly to Mathilde?
Answer:
Mathilde returned the necklace after so many days. Madame Forestier did not like it and was angry with Mathilde. It is the usual tradition to return the borrowed things immediately after the work is done, but Mathilde did not do it. By speaking coldly Madame Forestier expresssed her anger and displeasure.

Question 7.
What is meant by the horrible life of the very poor?
Answer:
The horrible life of the poor means a very tiring, bad, unpleasant and painful life. The poor are the people who live a miserable life with very little or no money at all. They have no money to satisfy their day-to-day basic needs. They have to work hard all the day to make both ends meet. Mathilde experienced this horrible life of the poor for saving money to clear the debt.

Question 8.
Write what you think about the following thought and action of Mathilde :
Mathilde told her friend about the lost necklace.
Answer:
Mathilde was now a relieved person. Though it was her fault, she must have thought that she should tell the truth to her friend and tell her how she struggled for ten long years that made her look old.

Question 9.
Who do you think was responsible for Mathilde’s misery? Was it her friend, she herself, her husband or the circumstances?
Answer:
It was Mathilde who was mainly responsible for her misery. Her wilfulness and obstinate behaviour were the root cause of the disastrous incident. She borrowed the necklace and lost it and that led to her misery. Her friend and her husband were, in no way, responsible for it. Of course the circumstances, to some extent too are responsible for it.

Question 1.
Prepare a speech to deliver in an interschool competition on ‘How to achieve success in life’ with the help of the following web chart:

Answer:

How to achieve success in life?

Honourable chairperson, respected headmaster, teachers and my dear friends, Today I am going to limit my speech on “How to achieve success in life:” I request you to listen to me carefully. So my friends, success is very important in everyone’s life. Everyone has a dream of becoming a successful human being in life. There is a good saying that, “Success is a journey and not a destination.”

How true it is! If we look at the life of all successful people, we realize the truthfulness of the statement. The definition of success is different for every person. For a child success is to solve a puzzle, for a S.S.C. student, a success is to get good marks, for a businessman, a success is to get a contract and for grandparents, success is to see the whole family together.

Everyone wants to become rich and successful in life. To achieve ambition, there are many steps which are to be followed. First of all, we have to set our goal, means we have to decide what we are and what we want to be. So proper plan and execution of the plan are very important. The tragedy of life does not lie in not reaching the goal, the tragedy lies in having no goal to reach.

For a great success we need a lot of confidence, patience, knowledge, perseverance and hard work. We should not waste our time because time is money. Don’t compare yourself with any other person in the world. If you do so you are demeaning yourself. The main thing is that we should always think positively and never give up hope because many of our failures are the people who did not realize how close they were to success when they gave up.

Always remember that the word “Impossible” means, I’m possible and if destiny is accompanied with the three D’s: determination, dedication, and devotion then everything becomes possible. We should learn from our own mistakes. We should always follow in the footsteps of great, successful people. Let’s take an example of Dhirubhai Ambani.

He was born in a poor family, but struggled a lot to achieve his ambition and never gave up hope because he knew that there is always a room at the top. He kept the hope alive in his heart and tried his level best and as you know he was one of the richest industrialists in the world. After all, no gains, without pains.

There is a great saying that successful people do not do different things, they do things differently. So work hard, continuously. God’s blessings are always there with you. Thank you for listening to me carefully.

Jai Hind.
