All About the Earth's Crust The Earth's crust is an extremely thin layer of rock, like the skin of an apple in relative terms. It amounts to less than half of 1 percent of the planet. But the crust is exceptionally important, and not just because we live on it.The crust can be thicker than 80 kilometers in some spots, less than one kilometer in others. Underneath it is the mantle, a layer of rock some 2700 kilometers thick that accounts for the bulk of the Earth.The crust is primarily made of granite and basalt while the mantle beneath is made of peridotite.he crust can be thicker than 80 kilometers in some spots, less than one kilometer in others.

Crust (geology) The crust is a thin shell on the outside of the Earth, accounting for less than 1% of Earth's volume. It is the top component of lithosphere: a division of Earth's layers that includes the crust and the upper part of the mantle.

How Plate Movement Affects Earthquakes, Tsunamis & Volcanic Eruptions Also known as the 'crust,' this thin, solid layer is much more than meets the eye. If Earth were an apple, the skin of that apple could represent the crust in terms of thickness and location. But unlike an apple skin, Earth's crust isn't one large piece covering the entire planet.

What Best Describes the Relationship Between Earth's Crust & the Lithosphere? The crust is the thinnest of the Earth’s three layers and the top part of the lithosphere. It is only about 8 kilometers (5 miles) thick under the oceans and 32 kilometers (20 miles) beneath continents.The rocks in the crust are primarily made of oxygen, silicon, aluminum and iron.ore About the Mantle. The crust is an important part of the lithosphere, but below it lies the other component: the top part of the upper mantle. This is denser than the crust. Like the crust, it contains rocks with large amounts of silicon and oxygen, but the mantle also has significant amounts of iron and magnesium.

Continental crust The continental crust is the layer of granitic, sedimentary and metamorphic rocks which form the continents and the areas of shallow seabed close to their shores, known as continental shelves. It is less dense than the material of the Earth's mantle and thus floats on top of it. Continental crust is also less dense than oceanic crust, though it is considerably thicker; mostly 35 to 40 km versus the average oceanic thickness of around 7-10 km. About 40% of the Earth's surface is now underlain by continental crust.

Oceanic crust Oceanic crust is the uppermost layer of an oceanic tectonic plate. The crust overlies the solidified and uppermost layer of the mantle. The crust and the solid mantle layer together comprise an oceanic plate.The plates of the Earth together are referred to as the lithosphere.Oceanic crust is the result of erupted mantle material originating from below the plate, cooled and in most instances, modified chemically by seawater.This occurs mostly at mid-ocean ridges, but also at scattered hotspots, and also in rare but powerful occurences known as flood basalt eruptions.ceanic crust is the result of erupted mantle material originating from below the plate, cooled and in most instances, modified chemically by seawater.

Crust (geology) Crust (geology) In geology, a crust is the outermost layer of a planet. The crust of the Earth is composed of a great variety of igneous, metamorphic, and sedimentary rocks. The crust is underlain by the mantle. The upper part of the mantle is composed mostly of peridotite, a rock denser than rocks common in the overlying crust. The boundary between the crust and mantle is conventionally placed at the Mohorovicic discontinuity, a boundary defined by a contrast in seismic velocity.

- These observations, along with many other studies of our planet, support the theory that underneath the Earth's crust (the lithosphere: a solid array of plates) is a malleable layer of heated rock known as the asthenosphere which is heated by radioactive decay of elements such as Uranium, Thorium, and Potassium.
