Lunar Highlands

The Lunar Highlands refer to the elevated, mountainous regions on the Moon's surface, contrasting with the darker plains known as maria. These highlands are primarily composed of ancient, rugged terrain formed by older volcanic activity and impacts from asteroids and comets. They are more heavily cratered than the maria and appear brighter when observed from Earth. The highlands cover about 83% of the Moon's surface and are crucial for understanding the Moon's geological history and formation. These areas are primarily composed of a rock called anorthosite, which is lighter and more reflective than the basalt found in the maria.
