Question

What are the major atmospheric layers?

Answer

The Earth’s atmosphere is divided into five major layers, which are:

1. Troposphere: This is the lowest layer of the atmosphere, extending from the Earth’s surface to an altitude of about 7-20 kilometres.
2. Stratosphere: This layer extends from the top of the troposphere to an altitude of about 50 kilometres.
3. Mesosphere: This is the third layer of the atmosphere, extending from the top of the stratosphere to an altitude of about 85 kilometres.
4. Thermosphere: This layer extends from the top of the mesosphere to an altitude of about 600 kilometres.
5. Exosphere: This is the uppermost layer of the atmosphere, extending from the top of the thermosphere to the edge of space.
