Transcript

  • 1. • Sedimentary rocks form at the earth’s surface by thelithification of sediments deposited from their transporting.• Typically rocks that are formed from sediment depositedfrom the air or water.Transporting:• When material is transported downhill.• Transport agents include: water, wind, ice, and gravity.
  • 2. • A geological process by which material is added to a landformor land mass• For example: Wind and water, as well as sediment flowing fromgravity, transport previously eroded sediment, causing layers ofsediment to build up.
  • 3. • The Rock Cycle are the processes that rocks undergo in the earth’scrust.
  • 4. There are two ways thatsedimentary rocks areformed:Pressure:• As layer after layer ofsediments are deposited, thelower layers are pressedtogether tightly under theweight of the layers above.Cementing:• Some sediments are gluedtogether by mineralsdissolved in water.
  • 5. Some different types of sedimentary rocks are:1) Clastic sedimentary rocks2) Chemical sedimentary rocks3) Organic sedimentary rocks
  • 6. • Clastic rocks are the more common type of sediment rock.• Clastic rocks form from cemented sediment grains that are fragments of pre-existing rocks.• An example of a clastic rock is Sandstone:
  • 7. • Precipitated from an aqueous environment.• Either directly by inorganic processes or by the actions of organisms.• Chemical rocks include carbonates, chert and evaporates.• An example is limestone:
  • 8. • Accumulate from the remains of organisms.• An example of organic rocks is coal. It forms from the compression of plant remains.
