My hobbies include rock collecting and macaroni art. Aren't rocks cool?

Thats awsome! The rise in popularity of geology is that you can start just by picking up any rock!

That is so true. Even when I don't know what kind of rock I have, I can still admire it. Do you know about the different types of rocks in geology?

Im not too sure I know there are three different types of rock. However the names of them escape me. Do you know?

I remember Igneous and Metamorphic are types, but I think one of them is from volcanos?
