Sedimentary Rocks Scaffold

Types of Sedimentary Rock:

  1. ______________________________________________
    1. Clay and silt → ___________________________________________________
    2. Sand → sandstone
    3. Gravel → ___________________________________________________
  2. ___________________________________________________
    1. Carbonate sand and mud → _______________________________
    2. Iron oxide _______________________________ → iron formations
    3. Siliceous sediments → chert
    4. _______________________________ → coal, oil, gas

The origin of a sedimentary rock involves:

  1. Weathering (_______________________________) of pre-existing rocks at the Earth's surface.
    • _______________________________ Weathering
      1. water _______________________________ minerals
      2. _______________________________
      3. dissolving by _______________________________ (carbonic and sulfuric)
    • _______________________________ Weathering
      1. changes in _______________________________
      2. _______________________________ action
      3. ______________________________________________________________
      4. _______________________________
      5. _______________________________ by moving particles
  2. Erosion (_______________________________) and _______________________________ of the weathered material. The causes of erosion are:
    1. _______________________________
    2. _______________________________
    3. _______________________________
    4. _______________________________
  3. Deposition (______________________________________________________________) of the material in the sea or some other sedimentary environment.
    • This usually happens when the transporting agent (wind, water, etc) _______________________________ and _______________________________.
    • It takes _______________________________ to carry sediment.
    • If there isn't enough _______________________________ the sediment settles out and is _______________________________.
    • How well the sediments are separated by particle size is called _______________________________.

  4. _______________________________ of the sediments. Lithification is when sediments turn to hard rock by being:
    1. _______________________________ by the weight of more sediment.
    2. _______________________________ by minerals like calcite, silica and iron oxides.

      This is the _______________________________ lithification process.
