Plate Tectonics

Plate tectonics is a scientific theory that the Earth’s surface is composed of a shell of moving crust. This shell is fractured into separate plates, which slowly glide across the mantle below. In this map, you can see the major, and some of the minor, tectonic plates. Familiarizing yourself with plate tectonics will help you understand the physical and ecological processes that shape the Earth’s surface.

Earth's Tectonic Plates: Detailed Description

Take a moment to learn more about plate tectonics by viewing the video, Plate Tectonics: An Introduction, from eMediaVASM. As you watch the video, think about how the United States may be different in the future due to this ongoing process.
