Question

What is the part of the atmosphere in which most of the air is present called? How thick is this part?

Answer 1

• The blanket of the air around the earth is called the atmosphere.
• The main layers of the atmosphere are:-

1. Troposphere- Most of the air is present in this layer of the atmosphere. The thickness of the troposphere changes from about 8 Km over the poles to about 16 Km over the equator.
2. Stratosphere- It contains a little amount of water vapor. The temperature of the stratosphere is more than that of the troposphere.
3. Mesosphere- It is a very cold layer and most meteors burn up in this layer.
4. Thermosphere- In this layer temperature increases with altitude.

• Troposphere is the part of the atmosphere in which most of the air is present. The thickness of the troposphere changes from about 8 Km over the poles to about 16 Km over the equator.
