The term used for the layer of unconsolidated weathered material, which includes mineral grains, rock fragments and other superficial deposits which lie above the solid bedrock.

a layer of loose rock and rocky debris sitting on the top of a hard surface; The regolith of the Moon was produced by meteors striking the Moon's surface.

The layer of loose, heterogeneous material lying on top of bedrock; includes soil, unweathered fragments of parent rock, and rock fragments weathered from the bedrock.

(reg' oh lith) - A mixture of rocky fragments covering the surface of an asteroid or planet, the product of "gardening" by repeated meteorite impacts.

Sediment derived directly from igneous rock and not containing any organically-derived materials

Weathered rocks, gravel, soil and such that covers bedrock.

The mantle of unconsolidated fragmental material that covers a land surface; i.e., soil and fractured rock.

Layer of loose mineral particles overlying the bedrock, which may be derived from weathering of the underlying bedrock or have been transported from other locations ___________________________________________________________________________________________________

A general term used in reference to unconsolidated rock, alluvium or soil material on top of the bedrock. Regolith may be formed in place or transported in from adjacent lands.

The blanket of soil and loose rock fragments overlying the bedrock.

The unconsolidated residual material that resides on the solid surface of the Moon (or Earth).

All layers of weathered rock, sediments and soil material covering the surface.

the "soil" that covers the solid rock on a planet's surface.

A general term for loose material overlying bedrock.

rock derived by weathering of bedrock

the layer of loose, broken, rocky material covering the surface of the bedrock. It includes all types of rock waste, together with superficial deposits of alluvium, peat, wind-blown sand and glacial drift.

the basal layer of soil, composed of material that is still recognisable as weathered rock or other geological deposits (such as alluvium); grades upwards into overlying subsoil.

A powdery soil layer on the Moon's surface caused by bombardment by meteoroids.

lunar "soil" composed of pulverized rock material

Weathered or sedimentary material that is over bedrock.

Surface debris on solar-system objects produced by impacting bodies.

Loose, unconsolidated rock, mineral and glass fragments. On the Moon this debris is produced by impacts and covers the surface.

Mantle of loose and weathered material overlying the bedrock.

A sheet of loose particles covering the bedrock. It plays a vital role in plant growth by creating soil.

The unconsolidated mantle of weathered rock, soil and superficial deposits overlying solid rock.

loose soil on the Moon created by rocks hitting the surface at very high speed.

deeply weathered bedrock produced by prolonged and intense decay of bedrock usually under tropical conditions. Remnants of preglacial regolith found in glaciated regions of Canada and Fennoscandinavia.

The layer or mantle of fragmental and unconsolidated rock material, whether residual or transported, that covers the bedrock

The layer of rocky debris and dust made by metoritic impact that forms the uppermost surface of planets, satellites and asteroids.

A fine rocky layer of fragmentary debris (or dust) produced mainly by meteoroid collisions with the surface of the Moon.

Any kind of unconsolidated debris that covers bedrock.

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. On the surface of the Moon, regolith is a fine rocky layer of fragmentary debris (or dust) produced mainly by meteoroid collisions.

Loose material, such as dust and rock fragments, covering bedrock.

a layer of soil and loose rock fragments overlying solid rock. [AHDOS

Regoliths are the loose, fragmented mantle rock fragments (of various sizes) and dust on a planet, asteroid, or moon surface. On the Moon's surface, regolith was formed by the meteorite bombardments of the Moon's crust; is the rocky debris which is thrown out of impact craters.

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. The term was first defined by G.
