Sedimentary

Sedimentary Rocks are formed from sediment which has settled at the bottom of rivers, lakes and oceans. Layer after layer of sediment is deposited on top of each other, then through time each layer is compressed down more and more, until the bottom layers slowly turn into a solid form of rock. Common types include Limestone, Mudstone, Shale, and Sandstone.
