What what causes earth rotation?

Answer 1

The earths rotation on its axis causes days and nights. When the rotates and it is dark, that means that your part of the Earth is facing away from the sun. If it is light out on your part of the Earth that means that your part of the Earth is facing the sun. And here is a fun fact: if your part of the Earth is light outside the part of the Earth on the exact opposite side is dark out!

Answer 2

Due to the gravitational force of the sun and gravitational force of the earth.

Answer 3

Days and nights, sunrises and sunsets.

Answer 4

It causes us to experience day and night.

Also causes change in tide, gravitational pull and Coriolis force- Deflection of objects (wind, ocean currents, missiles) from traveling in a straight path, in proportion to the speed of Earth's rotation at different latitudes. Deflection is to the right in the Northern Hemisphere and to the left in the Southern Hemisphere; maxium at the poles and zero at the equator.
The Earths rotation causes day and night. The revolution causes the seasons.

Answer 5

Conservation of angular momentum. The rotational velocities of the material coalescing to form the nascent earth 4.6 billion years ago would have been preserved, adding their own little bits to the final result.

Answer 6

Earth's rotation contributes to many things. The rising and setting of the sun is one of them. Coriolis is another.

Answer 7

the Coriolis effect

Answer 8

day and night

Answer 9

Day & night, wind & waves, tides.
