6: Sedimentary rock | Sedimentary rock forms when other rock sediments gather up using weathering and erosion and harden. They can change through melting and cooling or heat and pressure. | Sandstone is a type of sedimentary rock. It is used for headstones.
7: Limestone is also a type of sedimentary rock. It is used for children sidewalk chalk. | Coal is a type of sedimentary rock. It is used for energy and heat.
