→ Because of this, the same side of the Moon always faces Earth.
→ The Moon has no light of its own.
→ Its phases occur due to its position relative to Earth and Sun.
→ The Moon influences tides on Earth.

Correct Answer: (B)
Explanation:
→ Rotation means spinning of the Earth on its own axis.
→ Movement of the Earth around the Sun is called revolution, not rotation.
→ All other statements are factually correct.
→ Therefore, option (b) is incorrect.
Information Booster:
→ Earth completes one rotation in 24 hours.
→ Revolution takes about 365¼ days.
→ Earth is slightly flattened at poles.
→ It supports life due to air, water, and suitable temperature.
→ Earth lies in the habitable zone.
