4 1.Weathering Running water or wind breaks rocks or organic material into sediments (pieces of rocks, plants, animals).

5 Running water or wind carries away sediments.
2. Erosion Running water or wind carries away sediments.

6 Sediment drops out of water or wind.
3.Deposition Sediment drops out of water or wind.

7 Pressing of sediment together. (make-up compact)
4.Compaction Pressing of sediment together. (make-up compact)

8 Dissolved minerals crystallize and glue sediments together.
5.Cementation Dissolved minerals crystallize and glue sediments together.

Clastic Rock Sediments squeezed together to form a rock. breccia

11 Rock with remains of plants and animals forming layers.
Organic Rock Rock with remains of plants and animals forming layers. Limestone Coal

12 Minerals dissolved in a solution crystallize.
Chemical Rock Minerals dissolved in a solution crystallize. limestone gypsum halite
