Question

why does the speed of rotation decreases from the equator to poles?
​

Answer 1

Explanation:

The equator is further away from the (just imagined central pole) than the North and South poles. In this case, the same point on the equator has to travel a larger distance, a larger radius or call it circumference, to get to the same point. Therefore, the speed of rotation at the poles, decreases.
