Imagine that Earth stops orbiting the Sun but continues to rotate in place about its own axis at its current rate. In this case, what happens to the length of the solar day?

A It gets shorter.

B. It stays the same.

C. it gets longer

D. This question cannot be answered without additional information

The length of the solar day will get shorter.

Explanation:

The blue planet Earth not only rotates around it's own axis but also rotates around the Sun and everyday it moves a little bit around the axis. Since the speed of the Earth's rotation on it's own axis and around the Sun is constant we don't feel the effects of the rotation. We can only feel the motion if the earth changes it's rotation speed. If by any means or chance the Earth stopped spinning (stopped rotation) then the atmosphere surrounding the Earth would be in motion and all the Earth's land would be scoured clean.
