Earth's crust and the uppermost part of the mantle make up the lithosphere. The lithosphere is made of rigid rock. Because this rock is rigid, it may bend or break, but it will not flow. The lithosphere is broken up into many pieces called tectonic plates, or simply plates. Below the plates is the asthenosphere, which includes the rock in the middle part of the mantle.

What is the lithosphere?1 pointA) the plates that make up the crust and the upper part of the mantleB) the plates that make up the crustC) the upper part of the mantleD) large, flat stones sitting on top of malleable magmaClear selection

The lithosphere is broken up into tectonic plates. Choose two things that the theory of plate tectonics helps explain.

12.  What is a rigid layer made up of the uppermost part of the mantle and the crust?*1 pointLithosphereBiosphereAstenosphereSphere

the upper layer of the earth's mantle, below the lithosphere, in which there is relatively low resistance to plastic flow and convection is thought to occur.
