Document Summary
Sediment small solid pieces of material that comes forms rocks or living things. Erosion the process by which running water wind or ice carry away bits of broken up rocks. Deposition when sediment settles out of the wind and water carrying it. Compaction the weight of new layers squeezing older sediment tightly together. Cementation is the process by which dissolved minerals and glued particles of sediment together. Organic rock forms when the remains of plants and animals are deposited in layers. Clastic rock is a sedimentary rock that formed when rock fragments are a squeezed together the particles in clastic rocks can be fine. Rocks are made of sediments the were weathered, transported, and deposited in layers. Chemical weathering causes rocks to break down into chemicals. Rocks are formed from minerals that were dissolved in water, came out of solution, and were then deposited. Examples of weathering flowing water, moving ice, freezing and thawing and the growth of plants.
