1. Sedimentary Rock Classification and Formation

2. Weathering the breakdown of rocks into smaller pieces (sediments) over time due to heat, wind, water, ice, pressure and gravity http://www.geography.ndo.co.uk/animationsweathering.htm# http://www.uky.edu/AS/Geology/howell/goodies/elearning/module07swf.swf

3. Erosion  the movement of sediments caused by wind, water, ice and gravity http://serc.carleton.edu/NAGTWorkshops/visualization/collections/soil_erosion.html

4. Sediment  The minerals, sand, shells, small rocks and organic matter that make up sedimentary rocks.

5. Compaction Occurs when pressure brings sediments together. http://www.uky.edu/AS/Geology/howell/goodies/elearning/module05swf.swf

6. Cementation Occurs when minerals act as glue to stick sediments together This happens when water washes over sediments, leaving dissolved minerals behind http://www.classzone.com/books/earth_science/terc/content/visualizatio ns/es0605/es0605page01.cfm?chapter_no=visualization

7. Precipitation Occurs when minerals solidify because of water evaporation http://www.windows.ucar.edu/tour/link=/earth/geology/sed_chemical.html

8. Clastic Rocks from compaction and cementation of sediments (sand, shells, minerals, and small rocks)

9. Chemical Rocks  Form when minerals solidify into rock after the water they were dissolved in evaporates (precipitation)

10. Organic Rocks  from compaction and cementation of organic materials and/or sediments (sand, shells, minerals, and small rocks)  These are the only rocks that contain organic material

11. Features of Sedimentary Rocks Stratification: arranged in visible layers. Fossils: remains, impressions, or evidence of plant/animal existence preserved in rock. Ripple Marks: fixed sand patterns formed by wind, stream, waves, currents. Mud Cracks: muddy water dries out.
