Sedimentary Rock 10

  1. 1. Sedimentary RockStudents will be able toDescribe how rocks are formedClassify the sedimentary typesList uses for this rock type<br />
  2. 2. Changing Earth’s Surface<br />Weathering<br />Physical breaking of rock<br />Mass Wasting<br />Falling due to gravity<br />Erosion<br />Removal by mobile agents (water, wind, ice…)<br />
  3. 3. Weathering<br />Frost Wedging<br /> Water expands 9% when frozen<br /> Repeated cycles will break apart rocks<br />
  4. 4. Weathering<br />Unloading<br /> When pressure is released by exposure<br /> Rock cracks in sheets when it expands<br />
  5. 5. Weathering<br />Biological<br /> Damage caused by roots and animals<br />
  6. 6. Weathering<br />Chemical<br /> Acid rain, pollution, …<br />
  7. 7. Mass Wasting<br />Spheroidal<br />
  8. 8. Erosion<br />Loss of material<br /> usually loose soil<br />
  9. 9. Sedimentary Rock<br />5% of Earth’s outer crust<br />High Value<br />Contains major energy resources<br />Contains fossil record<br />
  10. 10. Formation<br />Compaction<br /> Weight of material on top presses into rock<br />Cementation<br /> Minerals enter spaces between to harden<br />
  11. 11. Types<br />Clastic<br />Rock fragments squeezed together<br />Organic<br /> Formed from remains of living things<br />Chemical<br /> Formed from chemical during evaporation<br />
  12. 12. Clastic<br />Shale<br /> 50% of all sedimentary rock<br />Made from tiny pieces of clay<br /> Black due to abundant carbon (living)<br /> Formed in oxygen poor area (swamp)<br /> “prevents decay”<br />
  13. 13. Sandstone<br />20% of all sedimentary rock<br />Small grains (wind or river)<br />
  14. 14. Conglomerate<br />Large particles<br /> Steep slopes or fast streams<br />
  15. 15. Organic<br />Limestone<br /> 10% of all sedimentary rock<br /> Mostly calcite<br /> Skeletons of coral reefs<br /> Accumulation of shells<br /> Caves from minerals above<br />
  16. 16. Coal<br />Many plant parts<br />Low oxygen formation (swamp)<br />High heat and pressure to solidify<br />Major source of US electrical energy<br />
  17. 17. Chemical<br />Evaporites<br />Seawater and salt flats evaporate<br />
  18. 18. Quiz<br />
  19. 19. Homework<br />Describe how sedimentary rocks are made<br />
