(A) We can see only that part of the moon which reflects light towards us
(B) Our distance from the moon keeps changing
(C) The shadow of the Earth covers only a part of moon’s surface
(D) The thickness of the moon’s atmosphere is not constant
🧠 Explanation:
- Phases of the moon are due to its position relative to Earth and the Sun.
- We see only the portion of the moon that reflects sunlight towards Earth.
- The moon orbits Earth, and different portions become visible as it moves.
- This changing visibility creates phases like new moon, half moon, and full moon.
