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

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 _________.
