The crust and upper mantle are called the?
The crust and the upper mantle are a geological part of the earth called the lithosphere. There are 2 parts of the lithosphere: the oceanic lithosphere, which is made up of land underneath water, and the continental lithosphere, which is the the part made of just land. The lithosphere lies on top of the asthenosphere. The lithosphere is made up of tectonic plates, which are pieces of land floating on the lithosphere.
Does continental lithosphere contain more mafic rocks than oceanic lithosphere?
No, oceanic lithosphere contains more mafic rocks compared to continental lithosphere. Oceanic lithosphere is mainly composed of basalt, which is a mafic rock, whereas continental lithosphere is composed of a variety of rock types, including granitic rocks which are more felsic in composition.
Why is oceanic lithosphere subducted while continental lithosphere is not?
The density of the continental (granitic) lithosphere is lower than oceanic (basaltic) lithosphere. Consequently, due to buoyancy, the continental crust rides above the oceanic lithosphere and thus is not subducted. However, it is thought that pieces of the continental lithosphere break off and are subducted along with the oceanic lithosphere.
What is the crust and the upper mantle are called?
The crust and uppermost hard rocky mantle, together, is known as the lithosphere, which is above the plastic-like upper mantle area known as the asthenosphere.
What is the average thickness of the lithosphere?
The average thickness of the lithosphere is around 100 kilometers, but it can vary depending on the location and whether it is oceanic or continental lithosphere. Oceanic lithosphere is typically thinner (around 5-10 kilometers) compared to continental lithosphere, which can be up to 200 kilometers thick.

What best describes the physical nature of the earth's lithosphere and the asthenosphere?
The lithosphere is rigid and commonly deforms in a brittle manner; the asthenosphere tends to flow slowly and deform in a plastic manner.
