Rock and the Rock Cycle

Rocks are always on the move through the rock cycle!

Click on parts of this rock cycle diagram to find out more about

  • sedimentary rocks
  • igneous rocks
  • metamorphic rocks

and how they change over geologic time!

All rock (except for meteorites!) that is on Earth today is made of the same stuff as the rocks that dinosaurs and other ancient life forms walked, crawled or swam over. While the stuff that rocks are made from stays the same, the rocks do not. Over millions of years, rocks are recycled into other rocks. Moving tectonic plates help to destroy and form many types of rocks.
