What is the earth's lithosphere made of?
Question Date: 2015-02-05
Answer 1:

Rocks. In particular a rock called peridotite that is made up of the minerals olivine, garnet and pyroxene.

Answer 2:

Rock, in a word. The lithosphere has two layers, an upper crust and a layer of solid mantle underneath. The crust in turn comes in two types - crust that makes up continents (which is mostly granite), and the crust of the oceans (mostly basalt). The upper mantle is made of a third rock type called peridotite.

Answer 3:

The Earth's lithosphere is made up of the crust and the topmost portion of the mantle (I hope you're familiar with these terms. I realize I might just be throwing random words at you.) The lithosphere is about 100 km thick on average, but there are some areas where it is thinner or thicker. Because it includes the crust, the lithosphere is very hard and rigid compared to all the other layers. It is composed of the rocks that we see on the surface of the Earth, plus a rock called peridotite (a very dense rock that is found at the uppermost mantle).

I hope I answered your question. Have a great day!

Answer 4:

Earth's lithosphere is the outermost shell of the planet: it consists of the crust and the outermost solid mantle The crust can be divided into two main categories: oceanic crust and continental crust. Oceanic crust is comprise of mafic (rich in magnesium and iron) and basaltic (volcanic) rocks. Oceanic crust is thinner but denser than continental crust, which is comprised of igneous, sedimentary, and metamorphic rocks.
