Explanation:

Rotation of earth induces centrifugal force which pushes any object away from the Earth’s
surface. Thus rotation doesn’t help atmosphere to bind to Earth’s surface.
Atmosphere filters the harmful rays from the Sun and also helps in controlling the
temperature so that life can be sustained.
Content of water vapour is highest near to surface of the Earth ie upto some 5 kms from the
surface, beyond that it reduces drastically.
