Summary
Do rocks rock your world? Then you’ll love following Tim and Moby as they take you on a tour of the types of rocks that can be found on and inside Earth. In this BrainPOP movie, you’ll learn about the three main types of rocks — igneous, metamorphic, and sedimentary. You can also discover the difference between lava and magma and find out what types of rocks these two semi-liquids form. Finally, you’ll see how pressure and heat can change the shape of mineral grains, changing one type of rock into another entirely. If rocks didn’t rock your world before, they will now!
