Types of Rocks

We learned all about the rock cycle this week.  There are three different types of rocks, metamorphic, igneous, and sedimentary and we found how they were made. Igneous rock is made when rock is exposed to very high temperatures, it melts, then cools and forms igneous rock. Sedimentary rock is made when little tiny pebbles and/or sand get smushed together, and metamorphic rock is formed when pieces of rock get smushed together and heated (but not melted). We were able to use Starbursts to make models of metamorphic and sedimentary rocks.
