Rock Cycle


Remember, Rocks tell stories!

All things being interconnected, you and the rocks around you may have be closer connected than you think. The silicon in your computer was locked up in rocks somewhere at some point. The rocks you walk on are only there because Africa, the U.S, and a few volcanic islands collided and metamorphisized the rocks around NYC a few hundred million years ago.

I have included a rock cycle picture for you to study, observe, copy, whatever! The whole point of the rock cycle is to show that any rock can become any other one. Heat from within the earth, new layers of rocks forming above, and plate movements can all change rocks below the surface. Volcanoes, weathering, and erosion can all change rocks on the surface. Nature is composed of cycles, swings in the balance, fast and slow changes that are always occurring. Enjoy the show, you are part of it!
