Question

The part of the mantle called the _____ is made of soft rock that bends like plastic

Answer 1

The correct answer is the astenosphere. It's part of the earth's crust that's just below the lithosphere and it's really susceptible to plastic flow because the resistance to it is very low. This is where scientists believe that convection occurs in the mantle. It's a very weak and easily deformed piece of the crust.
