Earth Science links. --a long list of geological links, maintained by Dr. Rebecca Dorsey of U of Oregon.
Geological Photographs. --index of photos on this website.
USGS site on plate tectonics A great deal of clearly presented and illustrated background.
UC Berkeley site --includes animations of the past 750 million years. Also summarizes the basic theory.
Introduction to Plate Tectonics --very informative site with excellent illustrations by Joe Stackhouse, a Pennsylvania High School teacher.
Rocks and Minerals
Minerals --information about just about every mineral there is! Go to minerals "by name" and pick what you want to learn about.
Photos of igneous, metamorphic, and sedimentary rocks --photos of outcrops
Photos of igneous rocks, textures, etc. --more photos.
Rock Cycle --Description with a great illustration from the University of Saskatchewan.
Rock Cycle --Description with another good illustration from U. of British Columbia.
