Question

1. which process is primarily responsible for the gradual slowing of earths rotation over millions of years?

a. atmospheric drag
b. tidal friction
c. volcanic activity
d. core solidification

Explanation:

Tidal friction, caused by gravitational interactions between Earth, the Moon, and the Sun, transfers angular momentum from Earth's rotation to the Moon's orbital motion. This transfer gradually reduces Earth's rotational speed over millions of years. Atmospheric drag has a negligible long-term effect, volcanic activity does not impact rotational speed in this gradual, sustained way, and core solidification does not drive this slowdown.

Answer:

B. Tidal Friction
