What is the theory that Earth’s surface is composed of several rock plates that fit together like the pieces of a puzzle A. metamorphism
B. plate tectonics
C. divergent plate boundary
D. geological shift

B.

Explanation:

Well, the crust of the Earth is broken into many pieces called plates. The mantle is the layer located directly under the sima. It is the largest layer of the Earth, 1800 miles thick. The mantle is composed of very hot, dense rock. This layer of rock even flows like asphalt under a heavy weight. This flow is due to great temperature differences from the bottom to the top of the mantle. The movement of the mantle is the reason that the plates of the Earth move! The temperature of the mantle varies from 1600 degrees Fahrenheit at the top to about 4000 degrees Fahrenheit near the bottom. Hope that this helps!
