Question

Quizplus · Accepted Answer

The term "lithosphere" refers to the outermost layer of the Earth, consisting of the crust and uppermost part of the mantle. This region is characterized by its brittle behavior and is distinct from the underlying asthenosphere, which is partially molten and exhibits ductile behavior. The Mohorovičić discontinuity (often abbreviated as "Moho") is a boundary within the lithosphere that separates the crust from the underlying mantle, but it is not a term used to describe the entire lithosphere as a whole. "Centrosphere" is not a recognized term in geology or Earth science.
