Rocks

I chose to look up more about rocks because I understood what I learned in class pretty well, but I was sure there was more I could know. I used the websites above which were mostly about igneous, sedimentary, and metamorphic rocks. An igneous rock is a rock that had once melted and later cooled and became solid. A sedimentary rock is a rock that is formed on earth's surface and a metamorphic rock is a rock that was once a igneous or sedimentary rock and was exposed to heat or pressure so high it became a sedimentary rock. This type of rock is buried deep in the earths' surface.
