Answer 2

There are four layers of the Earth=Troposphere, stratosphere, ionosphere, exosphere.
Troposphere is the lower layer of the atmosphere. This layer contains the optimum amount of air needed by living organisms to breathe. Winds and clouds are formed this layer. Weather changes also took place here.

The layer above the troposphere is stratosphere. There is less air here. Ozone layer is the part of this layer.

Above the stratosphere is ionosphere and exosphere. The thin layer of the ionosphere is electrically charged into radio Waves which helps to propagate.

Exosphere is the lower layer of the atmosphere. There is less air. Above the exosphere is space. There is no air in space.
