What is the primary source of erosion on the Moon?
Why does change take so long therecompared to Earth?
The dark areas on the moon’s surface are called maria, Latin for “seas,” and were once thought to be bodies of water. In fact, the maria are not “seas” at all, but plains of solidified lava. Given that there is no atmosphere on the moon, how can you explain the absence of liquid water on the moon’s surface?
What is the smallest size crater on the moon?
