The Most Helpful Online Geology Resources

Geology ResourcesThe elements of geology are all around us: in the ground beneath our feet, in the mountains we climb, in the rivers we swim. A plethora of information on geology, the study thereof and its impact on your life is available online—but there’s so much, it’s easy to get lost. We’ve gone through it all and did the hard work for you. Best Online College has compiled the most useful sites about geology and its related fields, with short descriptions to help you find exactly what you’re looking for quickly and easily.

Whether you’re hoping to find a colorful, kid-friendly page like “Earth—Our World in Motion” at the American Museum of Natural History or an interactive, multimedia guide like that of “The Dynamic Earth” at the Smithsonian National Museum of Natural History or a more in-depth analysis like the course lecture notes at Massachusetts Institute of Technology Introduction to Geology, you’ll find it here.

What is Geology?General Geology ResourcesUniversity Geology ResourcesResources for Kids


What is Geology?

The word “geology” means “the study of the earth”.  It comes from the Greek “ge,” meaning “earth,” and “logos,” meaning “word, speech or discourse.” Geology is the study of the earth—particularly its structure, origin, history and composition. Study of earthquakes, tectonic plates, volcanoes, types of rocks, and the formation of landforms (islands, mountain ranges, valleys, and others) all fall into the category of geology.
