what type of rock is the mantle composed of?

Answer 1

The rock of the mantle is not liquid, it is a solid that retains liquid properties due to the immense heat and pressure. It is considered to have plastic flow. The type of rock composing the mantle is an ultramafic silicate called peridotite, with a mineralogy of olivines and pyroxenes, along with minor minerals such as garnets. As the pressure/temperature relationships increase, minerals re-assemblages occur, such as olivine assuming the spinel structure at the 440-km discontinuity, and then assuming the perskovite structure at the 670-km discontinuity.

Answer 2

It sounds like your question is basically too obscure. i do no longer think of there is basically one answer for the two. Rocks may well be composed of many diverse aspects, minerals, or perhaps different rocks. Igneous rocks are shaped underground and then dropped on the provider the two truly rapid or truly slowly. that's the cooling of magma that kinds igneous rocks. greater on your question: Igneous rocks may well be composed of Granite; Rhyolite; Diorite; Andesite; Gabbro; Basalt; Peridotite.. and a selection of of different others as reported earlier. Metamorphic rocks are the melting and re-cooling of different rocks, the two igneous, sedimentary, or perhaps different metamorphic rocks. The metamorphism can ensue a number of diverse techniques, all having to do with warmth, and frequently rigidity.

Answer 3

It is a molten form of basalt. Basalt is an Iron rich silicatious material. You can watch it welling up from below in person when you visit the Hawaiian islands, since they are made of basalt. The Lunar maria are also made of basalt.

Answer 4

sollid of course

Answer 5

it isnt, it is molten lava
