Step-by-step explanation:

What is precession, and what causes it? Choose the correct answer.

a. Precession is a slow shift in the orientation of the Moon’s axis of spin.

b. Precession is a slow shift in the orientation of the Earth’s axis of spin.

c. Precession is a fast shift in the orientation of the Earth’s axis of spin.

d. Precession is a fast shift in the orientation of the Moons axis of spin.

In this class doing this assignment right now, b is correct answer

Answer 2

Precession occurs when the earth's axis changes direction over time caused by the gravitational pulls of the sun and the earth.
Obviously, there are gravitational pulls between the sun, the moon, and the earth. These gravitational pulls affect earth in such a way that it slightly changes its axis, which leads to precession. Precession is the term which refers to such a change in the orientation of a body, in this case, the earth.
