1. Changes to Earth’s Surface Unit
Week 24
Directions
Prepare your desk for science.
Science notebook
Use voice level 0 (no voice) and notebook pg. 61 to…
Answer the following question in writing: How are weathering and erosion similar and different?

2. Targets & Warm Up Targets:
Students will describe causes and effects of changes to Earth’s surface.
Students will determine where weathered material travels.
Warm Up: How are weathering and erosion similar and different?

3. Table of Contents Date Title Page 3-11-15 Deposition 62
Once you are finished with the Table of Contents, go to page 62 and add the title and date to the top of the page.

4. Deposit Deposit means… To put down in a specific place
To put for safekeeping
To make a payment

5. Deposition
The laying down of rock, soil, organic matter, or other material on the surface of Earth
In deposition, the larger pebbles settle to the bottom first. Then, smaller sand-sized particles sink. Finally, the smallest bits, called sand and clay, sink too.

7. Deposition Examples
Example 1: Waves carry sand away from one shoreline and drop it to form a beach

8. Deposition Examples
Example 2: Rivers deposit material where they flow into the ocean to form a delta
Delta: a triangular area where a river divides into a larger body of water

9. Deposition Examples
Example 3: Wind deposits silt and sand that forms a layer on top of the soil to create sand dunes

10. Question
Explain how weathering, erosion, and deposition work together. Use the drawing to help you explain your thoughts.

12. What is the difference between weathering, erosion, and deposition?
Reflection Question

13. Targets (Revisited)
Students will describe causes and effects of changes to Earth’s surface.
Students will determine where weathered material travels.
