Question

• A. Phases of the moon
• B. Tides
• C. Solar eclipse
• D. Melting of ice caps

Answer 1

The correct option is D

Melting of ice caps

There are many valid evidences to establish the fact that the Moon revolves around the Earth. One of the first known is the phases of Moon, which occurs due to the relative positions of the Sun, Earth and Moon. Solar eclipse and tides can also establish motion of the Moon around the Earth.

Now it is possible for the astronauts and instruments aboard space missions to observe the motion of the Moon around the Earth.

Global warming is the main reason for melting of ice caps, it is not related to the gravitational force between the Moon and the Earth.
