Rocks

Far back when Earth was just a "kid" like us, it was covered with tons and tons of rocks! Rocks are the main building material and can be found just about anywhere! There are three different types of rocks. First off, we have Mr. Igneous. Mr. Igneous is formed when lava or magma cools down. Next, we have Dr. Metamorphic. Metamorphic rocks are formed when rocks go under a lot of heat and pressure. Last but not least, we have Mrs. Sedimentary. Sedimentary rock is formed when layers of rock get smushed together.
