Unit Five - Weathering and Erosion - Deposition

Question 1

What is deposition?

Answer 1

Sediments that is dropped off.

Question 2

The sediment determines how fast they are deposited. What are the three factors?

Answer 2

1. Size - Larger Sediments will deposit faster
2. Shape - Rounded sediments settle faster and flatter sediments will settle slower (surface area)
3. Density - More dense sediments will settle faster

Question 3

Def. of Sorted Sediment

Answer 3

Layers of sediment that are similar in size, shape or density

(Ex: Deposition from a stream)

Question 4

Def. of Unsorted Sediment

Answer 4

Layers of sediment that are mixed in size, shape, or density
(Ex: deposition from a glacier)

Question 5

Def. of Horizontal Sorting (10)

Answer 5

1. Velocity
2. Wind
3. Water
4. Other Erosional system
5. Gradually decreases

SOOOO

6. Size
7. Roundness
8. Density
9. Gradually decreases
10. As you move father out.

Question 6

Def. of Vertical Sorting

Answer 6

Larger/denser sediments settle to the bottom first, followed by decreasing size/density.
