Only the deepest parts of this asthenospheric layer are hot enough to flow.  Core: The non-fluid core may be made of iron-rich rock.

What are the 2 craters we have learned about?  Small, slow objects have a low energy impact and cause small, simple craters.  Simple impact craters have bowl-shaped depressions, mostly with smooth walls.

What are the 2 craters we have learned about?  Large, fast objects release a lot of energy and form large, complex craters.  Very large impacts can even cause secondary cratering, as ejected material falls back to the ground, forming new, smaller craters, or a series of craters.
