Question

Describe the structure of atmosphere with the help of suitable diagram

Answer 1

Answer:

The atmosphere consists of almost concentric layers of air. ... Troposphere: It is the lowest layer of the atmosphere. It extends roughly up to a height of 9-10 km near the poles and about 18 km at the equator.

Answer 2

the atmosphere consists of four layers:-

1. troposphere
2. stratosphere
3. mesosphere
4. thermosphere

The troposphere is the lowest layer of the atmosphere. this is the layer where we live and where weather happens. temperature in this layer generally decreases with height. the boundary between the stratosphere and the troposphere is called the tropopause. The jet stream sits at which level and it marks the highest point that weather can occur. the height of the troposphere varies with location, being higher over warmer areas and lower over colder areas. above the tropopause lies the stratosphere. in this layer the temperature increases with height. this is because the stratosphere houses the ozone layer. the ozone layer is warm because it absorbs ultraviolet rays from the sun. the mesosphere is the layer above the stratosphere. the temperature decreases with height here just like it does in the troposphere. this layer also contains ratios of nitrogen and oxygen similar to the troposphere, axcept the concentrations are thousand times less and there is little water vapour there, so the air is too thin for weather to occur. the thermosphere is the uppermost layer of the atmosphere. in this layer the temperature increases with height because it is being directly heated by the sun.
