What is the mantle made of?

Answer 1

The mantle is divided into an upper and lower mantle. The mantle is much denser than crust material, and exists in a very dense molten soup that is compressed nearly solid by the intense pressure, similar to flowing stone that is also solid. There are convection currents that flow in this mixture that help move tectonic plates, and hotspots in the mantle that form calderas such as Yellowstone, which appear to move across the plate. In reality these hotspots are stationary, and the plate slides across the top, moving the caldera slowly across the plate.

In the mantle, look for high amounts of mafic rock. In general, however, the local mineral distribution depends on where you are at. Near a subduction zone, there will be more felsic material, but at a divergent plate boundary, you will find very heavy mafic minerals.

Answer 2

The Encyclopedia Britannica says mantle

That part of the Earth that lies beneath the crust and above the central core. On average, the mantle begins about 22 mi (35 km) below the surface and ends at a depth of about 1,800 mi (2,900 km). Predominant in the rock material are olivines,pyroxenes, and the silicate perovskite, a dense form of enstatite.

Answer 3

The mantle is mainly composed of solid rock, primarily made up of silicate minerals such as olivine and pyroxene. It is in a semi-solid state known as the asthenosphere, which allows for the movement of tectonic plates above it.

Answer 4

The mantle is made of incredibly hot rock, kept solid by immense lithospheric pressures.

Answer 5

the mantle of the earth is made of molten rock that sometimes pushes through the crust to form volcanoes. ha im smarter than you know
