1. Sedimentary Rocks

2. Sedimentary Rock Formation: Layers of sediment are deposited at the bottom of bodies of water. The layers get compacted from the pressure of the layers above. As the water is squeezed out, the salts present in the layers of sediment begin to crystallize. These salts help act as glue to hold the particles together.
