Answer to Question 1

The Moon lacks an atmosphere which means it has no weather. It also lacks a molten interior which means it has no plate tectonics. On the Moon the major form of erosion is meteorite bombardment, which is a very slow process. On Earth, wind and rain cause weathering (rapid erosion) of crater features. Plate tectonics is constantly changing the surface of the Earth, creating new crust and recycling old.

Answer to Question 2

TRUE
