magmatism.
Pulverized rock except where they have been filled with eruptive magma.

The moon is dormant. There isn't any lava on the moon, and there aren't any "kinds" of lava. If you're talking about magma, then there still aren't any types of it.
magma appears after a volcanic eruption.
Earth's tectonic plates ride on a sea of molten rock or magma, and it's possible that the moon's gravity exercises a pull on the magma in the same way as it affects ocean tides. This would be strongest at times when it (the moon) swings close to the earth, or when the sun and moon are in line with the earth in a sun-moon-earth alignment. Wonder if anyone has collected statistics on this.

The scientist was determined to get some magma to use in his research. Magma is the hot fluid that is in the Earth's crust.
To witness a volcanic eruption, one must be cautious of the flowing magma.
there was much magma after the volcanic eruption
Two types of moon craters are impact craters, formed by asteroids or meteoroids hitting the moon's surface, and volcanic craters, formed by volcanic activity on the moon when magma rises to the surface and erupts.
Yes, gabbro is a type of rock that can be found on the Moon. Gabbro is a common type of igneous rock formed from the cooling of magma. It is likely present in the lunar crust due to past volcanic activity on the Moon.
