Answer to Question 1

The shapes of craters can tell us the type of terrain in which they formed and whether they have been subject to erosion. Craters that form in rocky surfaces usually have a simple bowl shape. Craters that form in icy ground may look as if they formed in mud. Craters that lack sharp rims and bowl-shaped floors have probably been reshaped over time by erosion.

Answer to Question 2

E
