Homework Help: geology

Posted by nikki on Wednesday, May 25, 2011 at 9:43pm.

When astronauts brought back rock samples from the Moon, the minerals present were mostly the same as those found on Earth. Can you think of reasons why this might be so? Would you expect minerals on Mars or Venus to be the same, or at least very similar, to those on Earth?
