Final answer:
The Theory of Plate Tectonics explains the movement and interaction of Earth's plates.
Step-by-step explanation:
The Theory of Plate Tectonics states that Earth's outer shell is a series of plates that glide and move over the mantle. These plates sit on top of the Earth's surface and are constantly moving, causing earthquakes, volcanic activity, and the formation of mountain ranges. This theory explains how continents have drifted apart over millions of years and provides a framework for understanding the geography of Earth.
