- The solid, outermost layer of the Earth. ♦ The crust that lies underneath the continents is called continental crust, and is approximately 22 to 37 miles (35.4 to 59.6 kilometers) thick. It consists mostly of rocks rich in silica and aluminum, with minor amounts of iron, magnesium, calcium, sodium, and potassium.

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.

Crust (geology) The temperature of the crust increases with depth, reaching values typically in the range from about 200 °C (392 °F) to 400 °C (752 °F) at the boundary with the underlying mantle. The crust and underlying relatively rigid uppermost mantle make up the lithosphere.

Oceanic crust Oceanic crust is the uppermost layer of the oceanic portion of a tectonic plate. The crust overlies the solidified and uppermost layer of the mantle. The crust and the solid mantle layer together constitute oceanic 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 occurrences known as flood basalt eruptions.

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.

The Continental Crust: Definition, Formation & Composition There are two types of crust: continental and oceanic. Continental crust is the crust under which the continents are built and is 10-70 km thick, while oceanic crust is the crust under the oceans, and is only 5-7 km thick. The deepest mine shaft ever built (Western Deep in South Africa) currently reaches 3.9 km, which is tiny compared to the continental crust.

All About the Earth's Crust The Earth's crust is an extremely thin layer of rock that makes up the outermost solid shell of our planet. In relative terms, it's thickness is like that of the skin of an apple. It amounts to less than half of 1 percent of the planet's total mass but plays a vital role in most of Earth's natural cycles. The crust can be thicker than 80 kilometers in some spots and less than one kilometer thick in others. Underneath it lies the mantle, a layer of silicate rock approximately 2700 kilometers thick. The mantle accounts for the bulk of the Earth.

- The layers of dirt and silt that cover the crust are normally considered to be separate from it. The crust comprises the continents and ocean basins. It has a variable thickness, anywhere from 35-70 km thick in the continents and 5-10 km thick in the ocean basins.

- A single pie crust is just the bottom crust on a finished pie. For instance, a French Silk or pumpkin pie is a single crust pie.   A double crust is a pie that has a bott … om, filling and then a top crust to cover the pie. A traditional apple or blueberry pie is a double crust. An apple pie with a crumble topping instead of that second crust on top is a single crust pie.

Difference Between Lithosphere and Crust The word lithosphere comes from lithos, meaning rocks, and sphere. Thus, it is the study of rocks that form the surface of the earth and includes the crust, which is the skin of the earth and the uppermost mantle. This layer goes below the surface of the earth to about 70-100km.he surface of the earth down to the mantle that literally floats on the mantle is called the crust and is made of basalt and granite. The lithosphere is a layer that includes the crust and the uppermost portion of the asthenosphere.

Earths Crust The Earths crust is the outermost layer of our planet and is less than 1% of the Earth's volume. The crust and the mantle contain different kinds of rocks making them chemically different. The upper mantle rocks are primarily peridotite. The crust contains of a variety of rocks. Igneous rocks, sedimentary rocks, and metamorphic rocks are the main categories of rocks found on the Earth's surface.
