2. Sedimentary Rocks
Is when sediments of rocks, plants, or animals are cemented together, at or near the Earth’s surface.

3. Sedimentary Rocks
Forms through 5 processes: weathering, erosion, deposition, compaction, and cementation.

4. Weathering
Running water or wind breaks rocks or organic material into sediments (pieces of rocks, plants, animals).

5. Running water or wind carries away sediments.
Erosion
Running water or wind carries away sediments.

6. Sediment drops out of water or wind.
Deposition
Sediment drops out of water or wind.

7. Pressing of sediment together.
Compaction
Pressing of sediment together.

8. Dissolved minerals crystallize and glue sediments together.
Cementation
Dissolved minerals crystallize and glue sediments together.

9. Formed when minerals dissolved in a solution crystallize.
Chemical Rock
Formed when minerals dissolved in a solution crystallize.

10. Example A – Dolomite

11. Example B – Limestone (Chemical)

12. Sediments squeezed together to form a rock.
Clastic Rock
Sediments squeezed together to form a rock.

13. Layers in sedimentary rocks.
Strata (Stripes)
Layers in sedimentary rocks.
Ex.-Sandstone

14. The process called in which sedimentary rocks are arranged in layers.
Stratification
The process called in which sedimentary rocks are arranged in layers.

15. Conglomerate
rock composed of rounded fragments varying from small pebbles to large boulders in a cement (as of hardened clay)

16. Breccia
a rock composed of sharp or angular fragments embedded in a fine-grained matrix (as sand or clay)

17. Rock with remains of plants and animals forming layers; fossils
Organic Rock
Rock with remains of plants and animals forming layers; fossils

18. Example A – Coal

19. Example B – Limestone (Organic)
