Troposphere:
Extends from the Earth's surface to about 20 km of height.the height of the troposphere varies from
the equator to the poles
increasing towards the equator. The temperature in the troposphere
decreases with height. All weather phenomenon occurs in this region. The
transition boundary between the troposphere and the layer above is
called the tropopau
se.
Stratosphere:
Extends from the top of Troposphere to about 50 km above Earth's surface.
The temperature increases with height.The ozone layer is found in the
lower portion of the stratosphere. The transition boundary between
the stratosphere and the mesosphere is called the stratopause.
Mesosphere:
Extends from the top of Stratosphere to about 85 km above Earth's surface. The temperature decreases with
height. Most of the meteors burn up in this layer.
The transition boundary between the mesosphere and the thermosphere is called the mesopause.
Thermosphere:
Extends from the top of Mesosphere to about 600 km above Earth's surface.
The temperature increases greatly with height reaching upto 2000° at
the top of the layer. The ionosphere is a layer within the thermosphere.
Auroras are formed in this layer.
Exosphere:
Extends from the top of
Thermosphere to about 10000 km above Earth's surface. Satellites orbit the earth in this layer
