Answer:
The innermost layer of the atmosphere is TROPOSPHERE.
Explanation:
Atmosphere - The gaseous surroundings of earth is known as atmosphere. On the basis of variations in temperature, atmosphere has several layers as follows-
Troposphere- It is the innermost layer of the earth. extending 17 km above sea level at the equator and about 7 km above the earth's poles.Weather phenomenon occurs in this layer.It is known as troposphere because of vigorous air current.
Stratosphere- It is the second layer above troposphere.It extends approx 50 km above the earth surface.Ozone is also found in this layer. ozone plays very important role in maintaining thermal balance.
Mesosphere- It is the third layer of earth surface.Extending approx 50 to 85 km above the earth.Here temperature remains low.And at the top of this layer i.e, mesopause has the coldest temperature.
Thermospher- Temperature in this region is slightly high because of absorption of solar light.
Exosphere- It is the outer most layer of earth. Any particle or object in this layer if moving very fast can escape to the space. The exopause boundary of exosphere is approx 250-500 km above the surface. This is the transition layer between earth atmosphere and space
