Rock Cycle Animation

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.

The web page is located within Teachers'Domain, an online educational resource produced by WGBH Boston. It has two related components ? collections and courses ? that help teachers enhance their students' learning experiences and advance their own teaching skills. The Teachers' Domain collections include classroom-ready multimedia resources for use in lessons or independent study. Registration is free for everyone (teachers, students, parents).
