6 Written Questions

1. Sediment settles out of the water or wind carrying it. Eventually the moving water or wind slows down and deposits the sediment. If water is carrying he sediment, it sinks to the bottom of the lake or ocean.
2. skelotons and shells of sea animals-organic
3. when running water, ice, or wind loosens and carry away rock fragments. Destructive forces (heat, cold, rain, waves, and ice) constantly break up and wear away the earth's surface
4. Form when minerals dissolve in a solution, crystallize.
5. Rocks that form when particles of other rocks or the remains of plants and animals are pressed and cemented together in layers below the surface.
6. sand and gravel cemented together, resembles concrete-clastic

5 Multiple Choice Questions

1. - The process that presses sediments together. At first all the sediments fit together loosely, but gradually layer that are thick and build up. The weight of the layers further compacts the sediments, squeezing them tightly together. The layers are often visible.
   1. • Deposition
   2. • Cementation-
   3. • Compaction
   4. • Erosion
2. The process where dissolved minerals glue/crystallize particles of sediment together. While compaction is taking place, the minerals in the rock slowly dissolve in the water. It takes millions of years for compaction and cementation to transform sediment into rock.
