Original Description:
Everything goes in cycles, even rocks! In this BrainPOP movie, Tim and Moby explain how one type of rock can actually become another! You’ll explore the three types of rock — igneous, metamorphic, and sedimentary — and learn examples of each kind. How cool is it that one of these types is actually made out of living things! You also find out how heat, pressure, and erosion all play a part in the process that can transform igneous rock into metamorphic rock...and then back again. You’ll never look at a pebble the same way again!
