2. Title of notes: Sedimentary rocks pg. 14 & 15
Goal for lesson:
I can describe how a Sedimentary rock is formed.

Goal for lesson
I can describe how a Sedimentary rock is formed.
Today I am…
learning about the composition of Sedimentary rocks.
So that I’ll be able to…
understand how they are classified.
I’ll know I’ve got it when…
I can describe how they form.

4. What is a Sedimentary Rock?
A rock that forms when sediments are compacted and cemented together.

5. Sediment is material that is broken down by processes of weathering.
What is sediment?
Sediment is material that is broken down by processes of weathering.

6. Sedimentary rock formations
Weathering: When a rock breaks into fragments.
Erosion: The moving of materials.
(Shapes the Earth’s landforms.)

7. The Grand Canyon is an example of stream erosion through rock.

8. As layers of sedimentary rock are deposited, the layers become compressed or compacted.

9. Clastic Sedimentary rock
These particles may have originally been from igneous rocks, metamorphic rocks, or even other sedimentary rocks.
These are made up of pieces of pre- existing rocks / minerals.

10. Dissolved minerals separate out of the water and form a glue.
Chemical Sedimentary rocks
Dissolved minerals separate out of the water and form a glue.

11. Organic Sedimentary rocks
Forms from the build-up of organic debris (Ex. leaves, roots, or other plant/animal material.)

12. Where are Sedimentary Rocks formed?
Sedimentary Rocks are formed on or near the Earth’s surface.

13. Layers of Sedimentary Rock are called strata.

14. Examples of strata

16. Arizona – Colorado river erosion.
