The predominant rock in the Earth's crust and upper mantle is called silicate rock, composed mainly of silicon and oxygen. This type of rock is known as "peridotite" in the mantle and "granite" in the crust.

What is the state of the upper mantle?

The upper mantle is a solid layer of rock located beneath the Earth's crust. It is part of the Earth's mantle and extends from the base of the crust to a depth of about 660 kilometers. The upper mantle is mostly composed of peridotite, a dense rock made up of minerals like olivine and pyroxene.

What is crust and upper mantle of the EARTH?

The crust is the outermost layer of the Earth, consisting of solid rock that varies in thickness from about 5 to 70 kilometers. The upper mantle lies beneath the crust and is more rigid, extending to a depth of about 660 kilometers. Both layers are part of the Earth's lithosphere.

A rigid block of crust and upper mantle-rock is known as what?

A rigid block of crust and upper mantle-rock is known as a tectonic plate. These plates make up the Earth's lithosphere and can move and interact with each other at plate boundaries.

What are the two parts of the mantle?

The mantle has two parts: the upper mantle, which is directly below the Earth's crust and makes up about 15% of the Earth's volume, and the lower mantle, which extends from the top of the lower mantle to the outer core. The mantle is mainly composed of solid rock, but it can deform and flow slowly over long periods of time.

What layers make up the mantle?

The mantle consists of two main layers: the upper mantle and the lower mantle. The upper mantle is composed of solid rock that can flow slowly over time. The lower mantle is composed of solid rock under high pressure and temperature conditions.

What are the different layer of the lithosphere?

The lithosphere is divided into two layers: the crust and the upper part of the mantle. The crust includes the Earth's outermost layer that is divided into continental and oceanic crust. The upper part of the mantle beneath the crust is known as the asthenosphere.

What are the two parts of the mantle?

The mantle has two parts: the upper mantle, which is directly below the Earth's crust and makes up about 15% of the Earth's volume, and the lower mantle, which extends from the top of the lower mantle to the outer core. The mantle is mainly composed of solid rock, but it can deform and flow slowly over long periods of time.

Which earth layer is made of peridotite?

The Earth layer that is made of peridotite is the mantle. Peridotite is a type of rock rich in olivine and pyroxene minerals that primarily makes up the upper mantle beneath the Earth's crust.

What layers make up the lithosphere?

The lithosphere is made up of two layers: the crust and the uppermost part of the mantle. The crust is the outermost layer of the lithosphere and is composed of solid rock, while the upper mantle beneath it is also solid but more ductile.

What is the layer that makes up most of the earth's mass and vloume is the is what?

The layer that makes up most of the Earth's mass and volume is the mantle. It is located between the Earth's crust and core and is composed of solid rock that is capable of flowing over long periods of time. The mantle is divided into the upper mantle and the lower mantle, with the upper mantle being partially molten and the lower mantle being solid.

What two parts make up the lithosphere?

The lithosphere consists of the crust and the upper part of the mantle. The crust is the outermost layer of the Earth, while the upper mantle is the solid rock layer beneath the crust. Together, they form the rigid outer shell of the Earth.

Is the asthenosphere a plastic layer of rock in the mantle or is it a layer of earths crust and mantle?

The asthenosphere is a plastic layer of rock located in the upper mantle, below the lithosphere (earth's crust and uppermost mantle). It is responsible for the movement of tectonic plates due to its partially molten and ductile nature.

Is silica and forms of granite found in upper mantle?

Silica is found in the upper mantle, but not granite. Most of the minerals in the mantle are silicates, meaning they contain silica. Granite is found in the crust, primarily conditnental crust, as it forms from high-silica magma. The upper mantle is composed mostly of a lower-silica rock called peridotite.
