Astronomers can use the numbers of craters on different parts of the same world to provide important clues about how regions on that world evolved. On a given planet or moon, the more heavily cratered terrain will generally be

Answer 1

Astronomers can use the number of craters to understand the evolution of different regions on a planet or moon. Heavily cratered terrain is generally older as more time has passed since it was swept clean.

Step-by-step explanation:

Astronomers can use the number of craters on different parts of the same planet or moon to understand how those regions evolved over time. The more heavily cratered terrain on a given celestial body is generally older. This is because more time has elapsed since something swept the region clean. For example, the Moon is heavily cratered, indicating that it has preserved its impact history, while Earth's craters have been eroded by geological activity and the presence of an atmosphere.
