(A) We can see only that part of the moon which reflects sunlight light towards us
(B) Our distance from the moon keeps changing
(C) The shadow of the Earth covers only a part of the moon’s surface
(D) None of these
🧠 Explanation:
The changing appearance of the Moon, known as its phases, results from its revolution around the Earth. “Occurs” is a present tense verb indicating a natural, recurring phenomenon. As the Moon orbits, different portions of its sunlit side become visible from Earth, creating phases like new moon, crescent, quarter, gibbous, and full moon. Alternative ways to phrase this could include “caused by” or “result from,” but “revolves around” precisely explains the celestial movement responsible. Understanding this helps in astronomy, calendars, and tidal predictions, highlighting the relationship between Earth, Moon, and Sun in creating observable lunar patterns.
