My answer was a- m i rite?


Precession of earth's axis caused by the centrifugal force of the Earth's rotation... =)

The cause of the precession is the equatorial bulge of the Earth, caused by the centrifugal force of the Earth's rotation.That rotation changes the Earth from a perfect sphere to a slightly flattened one, thicker across the equator. the answer is-(The attraction of the Moon and Sun on the bulge is then the "nudge" which makes the Earth precess.)your answer is wrong......

Precession means the axis of the Earth is changing, so North changes.

Answer 1

b) They are asking for an effect CAUSED BY precession, not the cause of precession.
