The answer to this is D. It should be noted that there are always some differences with the way that the earth rotates. There is no fixed axis that is available but the earth tries itself to stay steady. The moon plays a huge role in the earth’s rotation because of the gravitational pull that it can provide. It allows the earth to stay in place.

The rotation speed is mostly constant as well. If the earth spins too fast, it may become the end of humanity and all of the other living things on earth. There are different reasons why the earth spins and rotates the way that it does. Let us hope that this will not change in the days to come.

The Earths rotation axis is not fixed in space. Like a rotating toy top, the direction of the rotation axis executes a slow precession with a period of 26,000 years (see following figure).
