Why does the surface of the moon appear to have so many more impact craters than that of the earth?

Answer 1

The Earth probably also had numerous craters but unlike the Moon, the Earth has an atmosphere and water that over time weather craters down. Also, plate tectonics on Earth tends to eventually subduct and destroy craters.

Answer 2

The Moon has more impact craters on its surface than Earth primarily because the Moon lacks a significant atmosphere to protect it from incoming space debris. Earth's atmosphere causes most smaller objects to burn up upon entry, reducing the number of impact craters on its surface.
