The moon is showing its same face to the earth because – (1) It is not rotating about its own axis (2) Its rotation and revolution are opposite (3) Its periods of rotation and revolution are the same (4) Its rotation is faster than its revolution

The moon is showing its same face to the earth because – (1) It is not rotating about its own axis (2) Its rotation and revolution are opposite (3) Its periods of rotation and revolution are the same (4) Its rotation is faster than its revolution
by

1 Answer

Answer :

(3) Its periods of rotation and revolution are the same Explanation: Because it is "tidally-locked" to the Earth. The Earth's gravity slows down the moon's rotation, so that it rotates at the same speed as it revolves around the Earth. Imagine a person who walks around a center pole, but shifts their body so they are always facing it as they walk.
