Multiple choice

The same side of the moon always faces the earth because

  1. moon and the earth have the same gravitational force

  2. moon cannot change its position

  3. the period of rotation of the moon on its axis and period of revolution around the earth is almost the same

  4. the period of rotation of the moon is not equal to the period of rotation of the earth

C Correct answer
Explanation

The Moon exhibits tidal locking, meaning its rotational period equals its revolutionary period around Earth (approximately 27.3 days). This synchronization causes the same hemisphere to always face Earth. It is not due to equal gravitational forces or inability to change position, but rather a natural consequence of tidal forces over time.
