What are the 2 characteristics of mantle?

Solution

  • The mantle is semi-solid.
  • It is rich in iron and magnesium.
  • This layer is about 2,850 km wide. Its average density is between 3.5 and 5.5.

What are the characteristics of the crust?

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.

What are the two characteristics of the core?

Core is the densest part of the Earth. It is divided into the inner and the outer core. The core of the Earth has a diameter of approximately 7000km. It is made up of Nickel (Ni) and iron (Fe) and thus it is also known as NIFE.

What are 5 facts about the mantle?

Okay, so here are the 5 facts about earth’s crust. It has formed during to a process called fractionation while Earth was cooling down and solidifying during its formation. Thus, the composition of crust, mantle and core are different. The most dominant elements on Earth’s crust are as following order. Oxygen, silicon, aluminium, Iron and so on.

What are the most common elements in the mantle?

In terms of its constituent elements, the mantle is made up of 44.8\% oxygen, 21.5\% silicon, and 22.8\% magnesium. There’s also iron, aluminum, calcium, sodium, and potassium. These elements are all bound together in the form of silicate rocks, all of which take the form of oxides.

It supports the crust, including deformation where the deep roots of mountains presses into the upper mantle. It receives subducted crustal and upper oceanic mantle, and takes it deeper into the mantle, where further differentiation and melting is facilitated by trapped sea water in pore spaces.

What are the two main factors in the mantle that?

The two most important things about the mantle are as follows: It is made of semi-solid rock. It is hot . Figure 1. Peridotite is formed of crystals of olivine (green) and pyroxene (black). Scientists know that the mantle is made of rock based on evidence from seismic waves, heat flow, and meteorites.
