The side facing the earth consists of dark (basaltic) lava filled basins called mare (maria) or seas. The lighter areas are heavily impacted terrain called the highlands.
What is the difference between maria and highlands on the Moon?
The Maria are mostly composed of dark basalts, which form from rapid cooling of molten rock from massive lava flows. The Highlands rocks are largely Anorthosite, which is a kind of igneous rock that forms when lava cools more slowly than in the case of basalts.
What is highlands on the Moon?

Why are the dark areas of the moon called mare?
The dark areas are known as “mare” (or maria) which is the Latin word for “seas”. They’re called maria because early scientists believed they could see oceans on the moon.

How many craters are on lunar highlands?
This value is much higher than the estimates of the mean crater densities for the lunar highlands (442 craters per 1 million km²), maria (73 craters per 1 million km²) and South Pole Aitken basin (393 craters per 1 million km²) obtained in previous studies [2,5].
What evidence indicates that maria on the Moon are younger than the highlands of the Moon?
Two pieces of evidence that indicates the lunar highlands are older than maria is that maria has few craters, and the highlands have large and more common.
How old are the highlands on the Moon?
It also established that the intense cratering of the highlands occurred more than 3.8 billion years ago. Most highland samples have ages in the range 3.8–4.3 billion years.
How did the highlands form on the Moon?
The Indian mission through the Moon mineralogy mapper has offered proof that the Moon’s highlands were formed by the eruption of a hot liquid inside the Moon’s surface popularly known as magma.
What are highlands on the Moon made of?
The maria are composed predominantly of basalt, whereas the highland regions are iron-poor and composed primarily of anorthosite, a rock composed primarily of calcium-rich plagioclase feldspar.
