what are the light colored areas on the moon called

The light-colored areas on the Moon are called the highlands. These areas represent the earliest crust on the Moon and are dominated by a type of rock called anorthosite, which is primarily made up of the white mineral anorthite or plagioclase. The highlands are mountainous regions that were uplifted as a result of impacts. In contrast, the dark areas on the Moon are called maria, which are smooth plains formed by lava. The basalt that flowed in and flooded the area created by a huge impact with an asteroid or comet formed these young plains.
