Question

Quizplus · Accepted Answer

The asthenosphere is often described as a "liquid-like" layer of the mantle due to its ability to slowly flow and deform over long periods of time.

Answer: B
 The upper mantle and crust form one continuous layer that is in contact with the Earth's surface. This layer is composed of rigid tectonic plates that move and interact with each other.

Answer: C
 The asthenosphere is located directly beneath the lithosphere (upper mantle and crust) and is thought to partially or completely melt over large areas. This molten layer can cause the lithosphere to "float" or move around on top of it.
