What are the 4 layers of the mantle?

The mantle is divided into several layers: the upper mantle, the transition zone, the lower mantle, and D” (D double-prime), the strange region where the mantle meets the outer core.

The upper mantle extends from the crust to a depth of about 410 kilometers (255 miles)..

What are the three layers of the mantle?

The mantle is composed of the mesosphere and the asthenosphere and the uppermost part of the mantle.

What are the two main layers of the mantle?

The Earth’s mantle is divided into two major rheological layers: the rigid lithosphere comprising the uppermost mantle, and the more viscous asthenosphere, separated by the lithosphere-asthenosphere boundary.

Is lower mantle solid or liquid?

Lesson Summary The lower mantle is the liquid inner layer of the earth from 400 to 1,800 miles below the surface. The lower mantle has temperatures over 7,000 degrees Fahrenheit and pressures up to 1.3 million times that of the surface near the outer core.
