Solution
Each point: 1 Mark
Explanation: 3Mark
1. The half of the moon which can never be seen from earth is called dark side of the moon.
2. It happens due to tidal locking or gravitational locking.
3. Gravitational lock, also known as captured rotation, is the tying of the orbital period of a planet or moon to its axial period through a tidal effect caused by the gravitational pull of the primary. The gravitational lock experienced by the Moon, for example, explains why it always keeps the same face directed toward the Earth.
