Introduction

The Great Rift Valley?  Sea Floor Spreading?? The Ring of FIRE??? You and your colleagues will investigate how plate tectonics has contributed to the evolution of the planet we call Earth.

 

 

Plate tectonics is the theory that the outer rigid layer of the earth (the lithosphere) is divided into a couple of dozen "plates" that move around across the earth's surface relative to each other, like slabs of ice on a lake.

 

 

This site provides an introduction to the different plate boundaries.
