The top and area of the earth's mantle that exhibits hard, brittle behavior together make up lithosphere. The lithosphere, which is mechanical layer's outermost layer and which exhibits stiff, brittle behavior.
What components makes up the lithosphere?
The Earth's solid outer layer, known as the lithosphere, is made up of earth materials. The whole crust and the uppermost layer of the mantle make up this structure. The asthenosphere, a solid rock layer in the upper mantle that resembles plastic, is on top of this hard layer rock that "floats."
Why would this be called lithosphere?
The crust and indeed the brittle uppermost portion of the lithosphere, the Earth's outermost layer, mantle. Greek words "lithos," which translate to "stone," are the source of the phrase "lithosphere."
