What is the mantle in information?

A mantle is a layer inside a planetary body bounded by a core and above a crust. The Earth's mantle is made of hot flowing rocks. The earth's mantle has a thickness of about 2,900 kilometers, which wraps up the earth's core. It is composed of silicate rocks that are rich in magnesium and iron; other rocks found in the mantle are magnesium oxide.

Other mantle elements include iron, aluminum, calcium, sodium, and potassium. The mantle is made of rocks or ices; they are the largest and most massive layer of the planetary body. The mantle is about 1,800 miles deep.

The Earth's mantle has two major rheological layers, which include the rigid lithosphere, which consists of the uppermost layer of the mantle, and the asthenosphere, which is separated by the lithosphere-asthenosphere boundary.

The mantle makes up about two-third of the earths mass; the most important item found in the mantle are diamonds.

The mantle is the Earth's second stratum. There are two parts to the mantle. There is the upper mantle, which has the crust above it, and it is attached to that crust. This creates the lithosphere, which is a fixed shell. From there, it is broken up into tectonic plates. Under the lithosphere, the asthenosphere can be found, which is the portion of the upper mantle that is less fixed.

Then, there is the lower mantle is the liquid layer of the earth. It can get very hot, exceed 7000 Fahrenheit. It has high pressure, and it accounts for 56% of the surface of the Earth.

The mantle is the second stratum of the Earth, and it has two main parts: the upper and lower mantle. The upper mantle is attached to the crust above it, and the result is a fixed shell called the lithosphere, which is broken up into sections called tectonic plates.

Below the lithosphere is the less fixed portion of the upper mantle called the asthenosphere. The temperatures can be so high within this region that there is liquid in places but only small parts. The soft liquid areas allow the plates to move, and occasionally rocks come through the surface by volcanoes that erupt. The mantle makes up about two-thirds of our planet’s mass, and it is full of rock, metals and the most important item would be diamonds.
