are two types of crust?
445831
Earth's crust is divided into two types: oceanic crust and continental crust. The transition zone between these two types of crust is sometimes called the Conrad discontinuity. Silicates (mostly compounds made of silicon and oxygen) are the most abundant rocks and minerals in both oceanic and continental crust.

Explain the difference between the crust and the lithosphere. The crust is the thin, outermost layer of the Earth that is composed differently than the mantle. The lithosphere is a thick layer that contains both the crust and the upper mantle (which is rigid compared to the underlying asthenosphere).

Continental crust consists mainly of less dense rocks such as granite. Oceanic crust consists of mainly denser rocks such as basalt. Oceanic crust is denser than continental crust. ... the layer of hot, solid material between Earth's crust and core.

Terms in this set (2) They differ by there rock types. Oceanic crust is made up of dense basalt while continental crust is made up of less dense granite.

Core, mantle, and crust are divisions based on composition. The crust makes up less than 1 percent of Earth by mass, consisting of oceanic crust and continental crust is often more felsic rock. The mantle is hot and represents about 68 percent of Earth's mass. Finally, the core is mostly iron metal.

The crust is the outer layer of the Earth. It is the solid rock layer upon which we live. ... Continental crust is typically 30-50 km thick, whilst oceanic crust is only 5-10 km thick. Oceanic crust is denser, can be subducted and is constantly being destroyed and replaced at plate boundaries.

There are three basic types of rock: igneous, sedimentary, and metamorphic. Extremely common in the Earth's crust, igneous rocks are volcanic and form from molten material.

What is the difference between the crust and lithosphere? The crust (whether continental or oceanic) is the thin layer of distinctive chemical composition overlying the ultramafic upper mantle. ... The lithosphere includes the crust (whether continental or oceanic) and the uppermost part of the upper mantle.

Despite being a significantly different material, the highest parts of the mantle are also rigid, like the crust. Therefore, the lithosphere includes both: the entire crust as well as the very top of the mantle. That is, the crust is all part of the lithosphere, but the lithosphere is more than just the crust.

Oceanic crust is about 6 km (4 miles) thick. It is composed of several layers, not including the overlying sediment. ... Oceanic crust differs from continental crust in several ways: it is thinner, denser, younger, and of different chemical composition.

Still, two major types of minerals exist: silicates and non-silicates. Silicates are those minerals that have silicon as a component, while non-silicates do not have silicon. As silicates form more than 90% of the earth's crust, we'll start with them.

Out of them, the mantle is the thickest layer, while the crust is the thinnest layer. The Earth can be divided into four main layers: the solid crust on the outside, the mantle, the outer core and the inner core. Out of them, the mantle is the thickest layer, while the crust is the thinnest layer.

Geologists recognize three main classes of structure caused by deformation in Earth's crust: unconformities, faults and fractures, and folds. We usually think of rocks as being very hard and brittle.
