Dynamic Earth is an interactive Web site where students can learn about the structure of the earth, the movements of its tectonic plates, as well as the forces that create mountains, valleys, volcanoes, and earthquakes.

The first section focuses on the layers that make up the earth — from the thin crust on the surface all the way down to the metallic core at the very center. Next, the interactive explores the concept of plate tectonics — the well-accepted theory that states the earth is broken up into about a dozen separate plates that are in constant motion. Students will learn the names of the tectonic plates and will be able to identify whether certain plates are moving toward, spreading apart from, or sliding past each other. Finally, students will learn how mountains and other structures and earthquakes and other major geological events are caused by the slipping, sliding, and colliding of tectonic plates.

Learning about the earth is an important topic for students of all ages. Global warming is a pressing social and environmental concern; to address this problem, students must become informed citizens. The Dynamic Earth interactive presents science concepts that every student needs to learn to better understand forces within our planet.
