1. Sedimentary Rock Notes pp. 102 - 105

2. 1. The Steps of any rock becoming a sedimentary rock are:
Sedimentary Rock Steps:
Weathering – breaking rock into smaller pieces or fragments of rock called sediment.
Erosion – moving smaller pieces from one place to another.
Strata – deposited in layers that continue to cover older layers.
Compacted – older layers are compressed/packed in on top of by other layers.
Cementation – a natural cementing that binds the rock and mineral fragments together into a sedimentary rock.

5. Sedimentary rocks are classified by the way they _____. There are ____ ways a sedimentary rock can form.
Form
Three (3)

9. Clastic Sedimentary Rock
Made of fragments of rocks cemented together.
Coarse Grain Example: Conglomerate
Medium Grain Example: sandstone, siltstone
Fine Grain Example: shale

10. Chemical Sedimentary Rock
Forms from solutions of dissolved minerals and water.
Example: Halite

11. Organic Sedimentary Rock
Forms from the remains of plants and animals that once lived in the ocean.
A fossil is a skeleton or imprint of the remains of plants or animals from long ago.
Examples:
Fossiliferous limestone
& coal.
