Question

--------- are the hole in the moon

Answer 1

Explanation:

There's a hole in the Moon! Actually, it's a pit, and there are several of these known in the lunar surface. ... When the lava flows away, you're left with a tube under the surface, like a subway tunnel. At that point, the roof of the tube can collapse in spots; on Earth this is common in Hawaii and other volcanic spots.15-Sept-2010
