Question

Which best describes precession?

A. Light from the sun strikes Earth at different angles.
B. Earth's axis wobbles.
C. Earth is tilted on its axis.
D. Light reflected by the moon is visible from Earth.

Answer 1

Earth axis wobbles

Step-by-step explanation:

Answer 2

B. Earth's axis wobbles

Step-by-step explanation:

Precession is where the Earth's axis essentially wobbles. Without this wobbling, the Earth's axis would point in a perpendicular, or 90 degree type of angle. This precession is caused by the gravitational pull of the Sun, along with the moon, and one period of precession lasts 26,000 years.
