1. Sedimentary Rocks By:Mathew Alcantara

2. What are Sedimentary rocks?
-2nd great rock class
-mostly underwater
-consist of layers of strata
(Strata)

3. Types of Sedimentary rock
Clastic
-made of mechanical weathering debris(Clasts)
-most common
-may contain shells and stones
Breccia Conglomerate

4. Types of Sedimentary rocks
Chemical
-when dissolved materials are separated from the solution
Iron ore Rock salt

5. Types of Sedimentary rocks
Organic
-made of remains of living organisms
-plants
-microscopic shells
(Coal)
(Limestone)

6. How are they formed? Weathering Deposition Erosion Lithification
-Breaking of rocks into smaller pieces or sediments
Deposition
-The transportation of sediments
Erosion
-the combination of weathering and movement of the resulting sediments
Lithification
-the process of changing of sediments into rock
-compaction
-cementation

7. How are they formed? How are they classified? Clastic Chemical/Organic
Compaction
-The process of turning sediments into rock via pressure
Cementation
-Minerals act as glue binding sediments together
How are they classified?
Clastic
-the size of the sediments
Chemical/Organic
-chemical composition

8. Clastic classification

9. Chemical/Organic classification
CaCO3
(Calcium carbonate)
SiO2
Silicon dioxide
CaH4O6S
NaCl
