Sedimentary Rock Formation

Sedimentary Rock Steps

1. Weathering rocks into sediments

2. Erosion to a sea (ocean) or lake

3. Deposition of sediment in layers

4. Heat, time, and pressure with minerals in water cause Compaction and Cementation

1st, Weathering

3rd, Deposition

• Deposition is when sediments are …

• H______ and P_________ increases as the layers build up, one on top of the other.

• These layers can contain the remains of dead _________ and __________ and even the imprints of __________ and footprints.

SKETCH

4th, Compaction or Cementation• The heat and pressure from layers and layers of

_____________ can cause compaction or cementation to form rock.

• Water between the _____________ particles evaporates and the minerals left behind act as a type of glue cementing the sediments together to form rock.

• The pressure is so great that the _____________ particles are compacted and lock together to form rock.

• All sedimentary rocks are formed from the weathered sediments of other types of _________.
