The maria (singular mare) on the moon contain igneous rocks and are dark-colored, fairly flat regions. Craters, however are circular depressions on the moon formed by the impacts of meteoroids.

The term is "crater" - a generally circular depression with a raised rim.

Particularly large objects striking its surface may create what is called an impact basin. It may include concentric rings or flows of melted rock.

NOTE:

The term "meteorite" more specifically refers to meteors found on the Earth's surface. While lunar craters are the result of a meteoric impacts, the objects that approach and strike the Moon are more accurately called meteoroids.

There are craters caused by asteroids. There are also low valleys called Maria.

Crescent is a phase of the moon visited both while waxing and waning; just before and after the new moon.

The term is crater : a typically round or elliptical depression with a raised ring. (The term is also applied on Earth to the caldera of volcanoes.) Particularly large meteor impacts can create what is called an impact basin, where there can be concentric rings caused by the flow of liquefied rock.

The other terms used for impact features are:

  • rays: lines of typically brighter ejected material around a crater
  • impact basin: multiple-ringed structure caused by large impacts
  • melt sheets: flows of rock liquefied by an impact

A type of valley found on the Moon is called a rille. It can be straight, as when caused by collapsed areas between faults, or channel-like, suggesting it formed from lava tubes.

Impressions on the moon are caused by meteors crashing into it, and they're called craters.

The question seems a bit mixed up, but you could mean "craters".
