the region of the earth from the surface to the Moho. The crust is part of the lithosphere and undergoes brittle deformation that causes earthquakes. The crust is divided into continetal crust which is thick, (30 - 60km) light, silica-rich, and old, and oceanic crust which is thin (20km) dense, silica-poor, and young.
The outermost compositional layer, or shell, of Earth (or any other differentiated planet). The crust consists of low density materials compared to the underlying mantle. Earth's crust is generally defined as the part of the Earth above the Mohorovicic discontinuity. It represents less than 1% of Earth's total volume. See also: continental crust, oceanic crust.
The outer part of the Earth, distinct from the underlying mantle. Oceans and continents have different types of crust. Oceans have relatively simple, thin crust (generally about 6-7 km thick) while the continental crust geologically is hugely complex. It is also much thicker (average about 30 km but up to 80km beneath some modern mountain ranges). The base of the crust is called the Mohorovicic discontinuity (or Moho).

The outer layer of Earth and other terrestrial planets.
The outermost and thinnest of Earth's compositional layers, the crust consists of rocky material that is less dense than the rocks of the mantle below. The continents make up the continental crust, and the crust beneath the oceans is the oceanic crust. The oceanic crust varies in thickness from 6 to 8 kilometers, and the continental crust varies in thickness from 30 to 70 kilometers.

A dense, cemented layer at the soil surface, usually only a few tenths of an inch thick, that is very hard when dry and inhibits water infiltration and seedling emergence. Crusting is most common on fine-textured soils (high in silt and clay) and is often caused by the impact of raindrops on soil that has been extensively tilled to produce a very fine seedbed.

The uppermost 5-70 km of the earth. There are two types of crust: continental and oceanic. Continental crust ranges from 10-70 km thick and has a composition approximating that of granite. Oceanic crust, on the other hand, is approximately 5 km thick and has a composition similar to basalt, making it significantly denser than continental crust.
In geology, a crust is the outermost layer of a planet, part of its lithosphere. Planetary crusts are generally composed of a less dense material than its deeper layers. The crust of the Earth is composed mainly of basalt and granite.
