The Adventures of Rocky and Rockster part2
This storyboard does not have a description.
Now that you're an igneous rock, can you tell me the differences between the types of rocks?

Of course. Every rock goes through the rock cycle eventually, and it usually takes a while. Now let's compare them!
This is a metamorphic rock, just like you! These rocks are formed deep inside the Earth, and have layers. Do you see the layers?
This is a sedimentary rock. Sedimentary rocks also have layers, just like metamorphic rocks. But metamorphic rocks don't have fossils in them, and aren't made up of sediment.
This is an igneous rock, just like me. Unlike the other two types of rocks, igneous rocks can be glassy, and crystals won't form. If the magma cools slowly, then the rock can form some crystals.
So metamorphic rocks and sedimentary rocks have layers, but sedimentary rocks contain fossils. Then igneous rock can be glassy if cooled fast, and forms crystals if it cooled slowly. Right?
Now I just have to wait a few million years to become a different type of rock.
Yup. Just remember that all the rocks are formed different ways, and they are all part of the never ending rock cycle.
WHY AM I STILL A METAMORPHIC ROCK!?!?
