Question

Choose the correct option.

• A. The shape of the moon changes every day and the various shapes seen during a month are called phases of the moon.
• B. Moon has no light of its own. We see only that part of moon, which reflects light of the sun to us. The position of moon changes due to its revolution around earth and hence the portion of moon reflecting the light of sun to us.

Answer 1

The correct option is B

Moon has no light of its own. We see only that part of moon, which reflects light of the sun to us. The position of moon changes due to its revolution around earth and hence the portion of moon reflecting the light of sun to us.

1. Moon didn't have its light. We can see the moon because of the reflation of the sunlight falling on us, and the shape of the moon changes because it revolves around the earth, so as much reflation is done, we can see.
2. So it takes approx. one month to make one revolution around the earth; hence after one-month shapes of the moon repeat themselves.

Hence, option B is correct.
