Regolith
Regolith (Greek: "blanket rock") is a layer of loose, heterogeneous material covering solid rock. Regolith is present on Earth, the Moon, some asteroids, and other planets.
Definition: regolith: The layer of rocky or icy debris and dust made by meteoritic impact that forms the uppermost surface of planets, satellites and asteroids.

Regoliths are the loose, fragmented mantle rock fragments (of various sizes) and dust on a planet, asteroid, or moon surface.
Regolith
The layer of loose rock resting on bedrock (sometimes called mantle rock), found on the Earth, the Moon, or a planet. Regolith is made up of soils, sediments, weathered rock, and hard, near-surface crusts.

The lack of water in the rocks and regolith also tells us something about the way that it formed. Right now, the currently favored theory about the origin of the Moon is the Impact theory.

Long before it was possible to observe these strange regolith properties in situ, Earth-based astronomers concluded that the Moon's surface must be very peculiar.
In contrast to Earth's soil, the lunar regolith contains no organic matter like that produced by biological organisms. No life whatsoever exists on the Moon. Nor were any fossils found in Apollo samples.
"These results may change dramatically the way we understood the solar wind-regolith interaction so far," says Yoshifumi Futaana of the Swedish Institute of Space Physics.
The dust is called regolith. Regolith is a rocky/dusty mixture which is produced by meteor impacts. With no atmosphere (and no cleaning staff), the dust from such impacts lays where it falls.
The Moon is coverered with a gently rolling layer of powdery soil with scattered rocks that is called the regolith; it is made from debris blasted out of the Lunar craters by the meteor impacts that created them.

Another piece of equipment will study the moon's soil, which is called regolith. The tool will also look for water ice near the moon's surface. Water, in the form of ice, on the moon could be used for many things.
The surface is covered with a gray, very dark regolith whose reflectance is only about 6 percent, or about one-half that of the lunar surface.
Seen in close-up, the lunar surface is strewn with a covering of loose fragments of rock and dust known as the lunar regolith. The regolith is simply the debris created by meteorites that struck the Moon at high velocity and then exploded.

The is the only natural satellite. The moon is a cold, dry orb whose surface is studded with craters and strewn with rocks and dust (called regolith). The moon has no atmosphere.
The rocks turned out to be ancient, suggesting no significant change since the surface of the Moon formed, about 4.5 billion years ago. The "soil" (regolith) had probably been pulverized by impacts, but as the "Surveyor" missions showed, ...
Other mechanisms that can cause atmosphere depletion are solar wind-induced sputtering, impact erosion, weathering, and sequestration — sometimes referred to as "freezing out" — into the regolith and polar caps.

Indeed, the impacting meteoroids and asteroids have ground a large portion of the Moon to dust! This dust, called regolith, covers most of the highlands and the maria like a thin blanket but may be up to 20 meters deep in some places.
The lunar surface is covered by a fine-grained soil called "regolith" which results from the constant bombardment of the lunar rocks by small meteorites.
The maria (which comprise about 16 percent of the Moon's surface) are huge impact craters that were later flooded by molten lava. Most of the surface is covered with regolith, ...
