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.
