Lunar rocky

Lunar rocky is a type of terrain.

Description
The most distinctive aspect of the Moon is the contrast between its bright and dark zones. Lighter surfaces are the lunar highlands, which receive the name of terrae (singular: "terra", from the Latin for Earth), and the darker plains are called maria, after Johannes Kepler who introduced the name in the 17th century.

The highlands are anorthositic in composition, whereas the maria are basaltic. The maria often coincide with the "lowlands," but it is important to note that the lowlands (such as within the South Pole-Aitken basin) are not always covered by maria. The highlands are older than the visible maria, and hence are more heavily cratered.
