Given below are two statements, one labelled Assertion (A) and the other labelled Reason (R).
Assertion (A): The same face of the Moon is always seen from the Earth.
Reason (R): The Moon takes about the same time to rotate once on its axis as it takes to complete one revolution around the Earth.
Choose the correct answer.
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Both A and R are true and R is the correct explanation of A.
Assertion (A): The same face of the Moon is always seen from the Earth. — Correct. From the Earth we always see the same side of the Moon; the far side can be seen only from spacecraft.
Reason (R): The Moon takes about the same time to rotate once on its axis as it takes to complete one revolution around the Earth. — Correct. Both take about 27 days. Because the Moon turns once on its axis in the time it goes once around the Earth, the same face keeps pointing towards the Earth, so R explains A.
