The rock cycle has no beginning and no end. Rather, it is an ongoing cycle in which rock — driven by tectonic processes such as volcanoes and earthquakes, the surface processes of weathering and erosion, and compaction — is created and destroyed. In this visualization and collection of animations from McDougal Littell/TERC, follow rock from its origins as magma through other stages of the cycle.
This media asset comes from Interactive Rock Cycle Animation by McDougal Littell, a division of Houghton Mifflin Company. Developed by TERC, Inc., Cambridge, Massachusetts.
