The maria were formed after large impacts from meteors carved out basins in the lunar crust. When the Moon was volcanic, magma seeped to the surface, filled the basins and eventually hardened, resulting in the relatively smooth flat areas seen today.

What is unique about the moon rotation and revolution?

“The moon keeps the same face pointing towards the Earth because its rate of spin is tidally locked so that it is synchronized with its rate of revolution (the time needed to complete one orbit). In other words, the moon rotates exactly once every time it circles the Earth.

What are the Seas called on the moon?

Mare Tranquillitatis (Latin for Sea of Tranquillity or Sea of Tranquility; see spelling differences) is a lunar mare that sits within the Tranquillitatis basin on the Moon. The mare material within the basin consists of basalt formed in the intermediate to young age group of the Upper Imbrian epoch.

What is Maria on the moon made of?

The Moon’s basaltic rocks are fine-grained composed mainly by iron, magnesium and titanium. The maria appear dark due to their high iron and titanium content that lead to about half of the highlands albedo. The highlands are formed by anorthosite that is a porous rock composed mainly of plagioclase feldspar.

What is the moon?
