1. Sedimentary Rock Notes

2. Weathering
Weathering is a process that breaks down preexisting rocks into sediment.
Caused by
Wind
Water
Ice
Sunlight
Gravity

3. Erosion
Through the process of erosion, sediment is moved from one place to another and deposited in layers.

4. Sedimentary Rock Formation
Sedimentary rock is formed when sediment is compacted and cemented together.

5. Strata
The most noticeable feature of sedimentary rock is its strata (or layers).

6. Sedimentary Rock Classification
Sedimentary rock is classified by the way it forms
3 main types:
Clastic
Chemical
Organic

7. Clastic Sedimentary Rock
Clastic sedimentary rock forms when rock or mineral fragments, called clasts, stick together.

8. Chemical Sedimentary Rock
Chemical sedimentary rock forms when minerals crystallize out of a solution, such as sea water, to become rock.

9. Organic Sedimentary Rock
Organic sedimentary rock forms from the remains of once-living plants and animals.

10. Sedimentary Rock Structures
Mud cracks: Form when fine-grained sediments at the bottom of a shallow body of water are exposed to the air and dry out.
Indicate the location of an ancient lake, stream, or ocean shoreline
Stratification: The process in which sedimentary rocks are arranged in layers.
Ripple marks: Marks in rock made by water and wind
