Give geographical reasons:

Question 1.
As we go higher in the troposphere it becomes cooler.
Answer:
1. The surface of the earth gets heated due to the heat of the sun.
2. So, the air near the surface is the hottest.
3. Therefore as we go higher in the troposphere it becomes cooler.

Question 2.
All weather-related phenomena take place in the troposphere.
Answer:
1. Almost all water vapour in the atmosphere is present in the troposphere.
2. Therefore, all weather related phenomena take place in the troposphere.

Question 3.
Mountaineers carry oxygen in cylinders when they climb mountains that are more than 5000 m high.
Answer:
1. As we go higher from the surface of the earth, the air in the atmosphere becomes rarer.
2. Therefore, mountaineers carry oxygen in cylinders when they climb mountains that are more than 5000 m high to get sufficient supply of oxygen.

Answer briefly:

Question 1.
What is a glacier?
Answer:

1. In cold regions, when layers of snow pile up on the ground, they form ice.
2. When such layers of ice pileup in a low lying area, they become enormous in size.
3. This huge mass slips down a slope at a very slow speed.
4. This is called a glacier.

Question 2.
What is groundwater? How can we obtain it?
Answer:

1. There is a lot of water stored in the underground layers of rock.
2. It is called groundwater.
3. We can obtain it by means of dug wells and bore wells.
4. Many lakes and wells get water from underground springs.

Question 3.
Explain ‘troposphere’.
Answer:

1. The layer of air that extends from the earth’s surface to a height of about 13 km is called the troposphere.
2. The conditions in the troposphere change continuously. As this layer touches the surface of the earth, the living world gets greatly affected.
3. As we go higher in the troposphere, the air gets cooler and rarer.
4. Almost all the water vapour in the atmosphere is contained in the troposphere. That is why, all weather-related phenomena such as formation of clouds, rain, fog, winds and storms takes place in troposphere.

Question 4.
How do we get rain?
Answer:

1. As the water vapour is lighter than air, it rises high up into the atmosphere.
2. As it goes higher, it cools and condenses into fine droplets of water.
3. These droplets are so small and light that they float in the atmosphere forming clouds.
4. These small droplets join together and form bigger drops that are heavy.
5. These heavy drops of water cannot float, so they fall down on the earth in the form of ‘rain’.

Write a note about the following:

Question 4.
Stratosphere:
Answer:

1. Beyond the troposphere, up to a height of about 50 km from the earth is the layer called the stratosphere.
2. In the lower part of the stratosphere, there is a layer of gas called ozone.
3. Ultraviolet rays coming from the sun are harmful for living things.
4. But the ozone layer absorbs them and protects the living world from those rays.
