Earth’s crust is altered by two closely related dynamic processes: the rock cycle and plate tectonics. In combination, these processes continually recycle and remodel Earth's solid surface, and reshape its oceans and rivers.

Watch as Dr. Gregory Vogt explains the relationship between the rock cycle and plate tectonics. He also demonstrates how rocks change and land features are transformed to shape our planet's topography. The presentation concludes with a primer on Earth’s three main rock types: igneous, sedimentary and metamorphic.
