Question

Define Rotation. Why is it important​

Answer 1

As the Earth rotates, each area of its surface gets a turn to face and be warmed by the sun. This is important to all life on Earth. This movement is called a revolution, which is different from rotation. Objects rotate around an axis, but revolve around other objects.

Answer 2

Explanation:

Rotation means a circular motion around a center. For example:-

Earth also rotates on its orbit around the sun.

It is important because Earth has life in it if rotation does not takes place so the half earth facing towards the sun will get overheated and another opposite half will get covered by ice and there will be no proper balance on the Earth..
