the precession of the earths axis of rotation takes about <how long?> to complete one cycle.
26,000 years
4.6 billion years
one year
3.8 million years
one day

Explanation:

Precession is the change in the orientation of the rotational axis of a rotating body. For a spinning - top, when it slows down and the axis of rotation changes direction, this is precession. The Earth's axis also precesses, and it takes approximately 26,000 years to complete one cycle.

Answer:

For the first question: B. precession
For the second question: A. 26,000 years
