what is All the rest of the mantle- made of hard hot rock- till it reaches the core.
1 answer
The rest of the mantle, also known as the lower mantle, is primarily made up of solid, dense, and hot rock. It is composed of various silicate minerals, such as peridotite and pyroxene. These rocks are rich in iron and magnesium and can withstand the high pressures and temperatures found in this region of the Earth's interior. The lower mantle extends from a depth of approximately 660 kilometers (410 miles) to the boundary with the core, which is about 2,891 kilometers (1,796 miles) deep.
