Answer:

• Due to continuous variations in the temperature, rocks develop cracks.
• Similarly, the water percolating through rocks dissolves the soluble minerals leading to the weathering of rocks.
• They get disintegrated or decomposed i.e. reduced to pieces.
• These rock particles get transported by rivers, glaciers, wind, etc. towards low lying area and are deposited there.
• One after the other, layers of sediments gets deposited in this way.
• The upper layers exert heavy pressure on the lower layers.
• This leads to compaction of materials and development of sedimentary rocks.

Question 2.
How are Metamorphic rocks formed?
Answer:

• Volcanic activity and other earth movements | constantly take place on the earth.
• While these are occurring, the igneous or sedimentary rocks in that region are subjected to tremendous pressure and heat.
• This leads to changes in the nature as well as the chemical composition of original rocks.
• The crystals in the original rock gets recrystalized, the rock gets metamorphosed.
• The rocks formed through such a process are ! called Metamorphic rocks.

Question 3.
How is sand that flows in a river formed? Collect some information about where the sand comes from.
Answer:

• Moving streams are so powerful that it can wear away soil rocks.
• Rocks on higher land get eroded due to the strong current of the streams and they in turn get carried away into the sea.
• Silt too is brought down from the mountain top from where the streams originate.
• Most of the sand in the river is silt carried by the streams and the weather material from inland rocks transported by the streams.
• The moving of soil and rock with the stream, termed as erosion can be summed up as the cause of sand formation in a river.

Answer:

• Waterways is a cost-effective, fuel efficient and relatively more environment friendly means of transportation.
• Large scale transport of goods can be carried out with the help of ships, trawlers, boats, etc. at a low cost.
• So it is economic to carry out transport by waterway.

Question 3.
Why There is a difference in the climate of regions close to the oceans and regions far away from the oceans.
Answer:
(i) The oceans influence the climatic condition of a place. Coastal areas are cooler and wetter than regions away from the ocean.

(ii) There is a difference in the maximum and minimum temperature with the difference being less in coastal region (nearness to the sea) while it is more in the region far away from the sea (continentality).

(iii) The temperature in coastal areas remains equable due to the mixing of vapour released through evaporation of water from these water bodies into air. This vapour absorbs and stores the heat released from the land.

Give geographical reasons for the following statements:

Question 1.
The ocean water is saltier than drinking water.
Answer:

(i) In drinking water, the proportion of salts is quite low. Water from oceans and seas has a greater amount of salt. Hence it tastes salty.

(ii) Volcanic eruptions leads to increase in the level of salts and minerals in ocean water.

(iii) Volcanic eruptions takes place in the oceans. During volcanic eruptions different minerals, ashes, salts and gases are added to the water. This increases the level of salts and minerals in ocean water.

(iv) Due to continuous evaporation of oceanic water, the proportion of salt increase.

Question 2.
The temperature in coastal areas remains equable.
Answer:

(i) In regions close to the oceans, seas or large reservoirs, there is not much of a difference in the temperature throughout the day.

(ii) The main reason for this is the mixing of vapour released through evaporation of water from these water bodies into air.

(iii) This vapour in the air absorbs and stores the heat released from the land.

(iv) Hence, the temperature in coastal regions remain equable.

Question 3.
It is economic to carry out transport by water ways.
Answer:

• Waterways is a cost-effective, fuel efficient and relatively more environment friendly means of transportation.
• Large scale transport of goods can be carried out with the help of ships, trawlers, boats, etc. at a low cost.
• So it is economic to carry out transport by waterway.

Question 4.
There is a difference in the climate of regions close to the oceans and regions far away from the oceans.
Answer:
(i) The oceans influence the climatic condition of a place. Coastal areas are cooler and wetter than regions away from the ocean.

(ii) There is a difference in the maximum and minimum temperature with the difference being less in coastal region (nearness to the sea) while it is more in the region far away from the sea (continentality).

(iii) The temperature in coastal areas remains equable due to the mixing of vapour released through evaporation of water from these water bodies into air. This vapour absorbs and stores the heat released from the land.

Question 5.
Oceans act as the controller of global temperature.
Answer:

(i) Winds move the oceanic water in the form of currents.

(ii) Ocean currents move from the equatorial region to polar regions and from polar regions to the equatorial region.

(iii) This leads to the redistribution of heat on the earth.

(iv) The cold currents moving towards the equatorial region making the temperature of coastal areas in that zone milder whereas the warm currents coming in the colder region cause the temperature in coastal areas to rise. Hence, the oceans act as the controller of global temperature.

Answer the following questions in brief:

Question 1.
What are planetary winds?
Answer:

• Equatorial regions receives perpendicular sunrays.
• As a result these areas get more heat whereas the polar regions receive highly slant rays.
• This differential heating creates imbalance in the temperature of air in different parts leading to formation of belts of high and low pressure on earth.
• Winds blow1 due to the pressure differences in these belts. These winds are called Planetary Winds.

Question 2.
Write in brief about oceanic transport.
Answer:

• Oceans have provided us the most economic option of transportation.
• Large scale transportation of goods is carried out with the help of ships, trawlers, boats, etc.
• International trade is carried out on a large scale using waterways.
• Countries like Spain, Norway, Japan have a good coastline due to which goods are transported by ocean routes, making these countries important.

Question 3.
How do ocean currents aid water transport?
Answer:

• Ocean currents are quite important in water transport.
• As far as possible water transport is carried out along ocean currents.
• They accelerate the speed of the ships and also save fuel to a considerable extent.

Question 4.
List the causes that lead to large scale pollution of oceanic water.
Answer:
The causes that lead to large scale pollution of oceanic water are:

• Oil spills.
• Releasing the waste produced in the coastal cities into the seas.
• Materials thrown out from ships.
• Exploitative fishing.
• Cutting of mangrove forests in coastal areas.
• Disasters caused by the water mines.

Question 7.
What is an annual range of temperature?
Answer:
The difference in the mean temperatures of summer and winter is called an annual range of temperature.

Give geographical reasons for the following statements:

Question 1.
There is unequal distribution of heat received from the Sun.
Answer:
The unequal distribution of heat received from the Sun is because:

• The earth is spherical in shape.
• The rays which fall on the equator are straight, occupy less area and give more heat.
• The rays which fall on the curvature i.e., on the polar regions are slant rays which occupy large area and give less heat.

Question 2.
The temperature near the sea level is higher and it decreases in the mountainous region.
Answer:

• Firstly, the sea water gets heated by the rays of the sun.
• The absorbed heat is later radiated into the atmosphere.
• So, the layer of air close to the surface gets heated.
• This heat gets transferred vertically to the adjacent upper layers of air.
• Therefore, the temperature near the sea level is higher and it decreases at the mountainous region.

Question 3.
In the coastal areas, as compared to continental areas, the temperature of air is lower during the day but warmer at night.
Answer:

• There is difference in the heating and cooling of land and water.
• The air over the land gets heated faster and also cools rapidly.
• The air over the water gets heated slowly and also loses the heat in a slower manner.
• The temperature of air is lower during the day but warmer at night, in the coastal areas when compared to continental areas.

Question 4.
Greenhouse gases lead to increasing temperature of the earth.
Answer:

• Some gases in the atmosphere like carbon dioxide and water vapour can hold the heat within themselves for a long period of time.
• Due to the gases, the temperature of air in the atmosphere increases.
• Thus, greenhouse gases lead to increasing temperature of the earth.

Question 5.
Regions, where warm and cold currents converge, are favourable for the growth of fisheries.
Answer:

• Regions, where warm and cold currents converge, are favourable for the growth of planktons.
• Planktons are the food for fishes.
• Fishes travel here in large numbers.
• They breed in warm waters and increase the number of fishes.
• Therefore, regions where warm and cold currents converge favour the growth of fisheries.

Answer the following questions in short:

Question 1.
Explain the movement of ocean currents from equator to the polar region.
Answer:
Due to temperature differences, both upward and horizontal currents develop in the ocean. Besides temperature differences, factors like winds and differences in the density of water also give rise to horizontal currents. These ocean currents flow from the equator to the polar region and from the polar region to the equator.

Question 2.
Explain the effect of the ocean current flows from the frigid to the torrid zone.
Answer:
When an ocean current flows from the frigid to the torrid zone, it reduces the temperature of the coasts in the torrid zone. When a current flows from the torrid to the frigid zone, it increases the temperature of the coasts in the frigid zone.

I can do this!

Question 1.
Identify the temperature zones.
Answer:
There are three temperature zones namely torrid, temperate and frigid zones.

Question 2.
Tell the factors influencing temperature.
Answer:
Factors influencing temperature are latitude, winds, nearness to the sea, continentality, vegetation cover, cloud cover, physical set up, height above sea level and industrialisation.

Question 3.
Describe the global distribution of temperature with its characteristics.
Answer:
The isotherms in the southern hemisphere are fairly parallel to the latitudinal lines. From South Pole to the Tropic of Capricorn the distance between these lines is almost equal. As the proportion of land in the southern hemisphere is limited, temperatures in these parts are largely influenced by latitude.

In the northern hemisphere, the distance between these lines varies. In this hemisphere, the proportion of land is comparatively greater. This affects the distribution of temperature. These effects are seen in the form of variations in the distance between the isotherms and curved nature of these lines.

Question 4.
Describe the structure of a thermometer.
Answer:
A vacuum glass tube is filled with mercury or alcohol is mounted on a wooden board. There are two temperature scales showing Celsius and Fahrenheit.

Class 6 Geography Chapter 1 The Earth and the Graticule Textbook Questions and Answers

Think a little!

Question 1.
A game of reading the meridians on the world map is going on. Shaheen and Sanket are asking each other to locate places on specific meridians and are making notes of the same. Shaheen asks Sanket to locate Wrangel Island on 180° meridians. Sanket could locate the island in the map but both are confused while making a note of it. They are puzzled whether to write 180° E or 180° W? What would be the precise answer? Please help them. Can we use a similar logic with reference to 0° meridian as well?
Answer:
The 0° and the 180° meridians lie opposite to each other and form a circle around the earth. This circle divides the earth in the eastern and western hemisphere. Shaheen and Sanket can write the Wrangled island to be loacted on 180° meridian.

Do it yourself!

Use figure 1.4 of the geography textbook:

In the upper portion of the circle, at the centre X, draw angles of 30°, V₁ X K₁ and V₂ X K₂; K₁ and K₂ being the points on the circle. Draw an ellipse joining K₁ and K₂.
In the lower half of the circle, mark angles of 60° and name the points on the circle as P₁ and P₂.

Question 1.
Draw an ellipse joining P₁ and P₂.
Answer:

Can you tell?

Question 1.
Is the distance between K₁ K₂ and P₁ P₂ the same?
Answer:
No, the distance between K₁ K₂ and P₁ P₂ are not the same.

Question 2.
Compare the distances XK₁ and XP₂. Are these distances the same or are they different?
Answer:
Yes, the distances are the same.

Question 3.
Now compare the ellipses you have drawn. Which is the larger ellipse? Why?
Answer:
The ellipse through K₁ and K₂ is larger than the ellipse through P₁ and P₂ . This is because the distance between K₁ K₂ is greater than the distance between P₁ P₂.

Observe the picture (fig) on page 5 of the textbook and answer the following questions:

Let the line AM be 0°.
Draw the line MB. Measure the angle it makes with the line AM and write it near B. Note the semicircle that passes through B and joins the North and South Poles. Trace it.
Now join MC. Measure ∠AMC and write it next to C. Draw a semicircle that passes through ‘C’ and joins the North and South Poles.
Draw a line that passes through point A at 0°, and joins the North and South Poles.

Answer:
∠AMB = 70°
∠AMC = 85°
