Students have asked these similar questions
Why are the lunar mountains smooth and rounded rather than having sharp, pointed peaks?
A. Because a sheet of ice once covered the moon’s surface billions of years ago.
B. Because they rose up from beneath the Moon’s surface due to an increase in pressure from its hot core billions of years ago
C. Because micro meteorites impacts have caused their gradual erosion
D. Because the moon once had sulfuric acid clouds long ago
If rocks obtained from the moon indicate an age of 4.5 billion years and the oldest rocks from Earth indicate an age of 4.4 billion years is the moon necessarly older than earth? Why or Why not?
