How do plate tectonics shape the Earth?

Plate Tectonics:

Plate tectonics refers to the movement of the Earth's crust. There are 7 major tectonic plates on Earth, and they are situated over a molten mantle. The mantle is heated and liquified by heat generated in the Earth's core.

Answer and Explanation:

There are many ways in which plate tectonics shape the land. One is by moving and breaking apart the continents over hundreds of millions of years. Another is by forming mountains. A third is by causing volcanic eruptions. These eruptions not only destroy old land, but create new lands, as well. For example, Iceland and the Hawaiian islands were created by volcanos.
