Plate Tectonics, The Force That Builds Mountains
The Earth is covered with a thin, brittle crust. Below the crust is the mantle, a region where solid rock below a certain depth stretches like rubber.
The crust floats on top of Earth's mantle like the crust of grease that forms on top of a pot of chili or chicken broth in the refrigerator.
