1. Chapter 14 Quiz Review

2. Question #1 Q: What is mechanical weathering?
A: Process by which rocks are broken down into smaller pieces by physical means.

3. Question # 2
Q: Name at least 3 common agents of mechanical weathering.
A: ice, plants, animals, gravity, running water, and wind.

4. Question # 3 Q: What is abrasion?
A: The grinding & wearing away of rock surfaces through the mechanical action of other rock or sand particles.

5. Question # 4 Q: What is chemical weathering?
A: Process by which rocks break down as a result of chemical reactions.

6. Question # 5 Q: What are the 5 types of chemical weathering?
A: Oxidation, hydrolysis, carbonation, organic acids, & acid precipitation.

7. Question # 6
Q: What is produced when carbonic acid reacts with calcite ( a major component of limestone)?
A: Calcium bicarbonate

8. Question # 7
Q: What are the 4 agents that affect the rate of weathering?
A: Rock composition, surface area, climate, & topography.

9. Question # 8 Q: What weathering agents do lichens & mosses produce?
A: Organic acids

10. Question # 9
Q: If you increase the amount of surface area, how does that affect weathering?
A: The larger the surface area, the higher the rate of weathering.

11. Question # 10
Q: Sedimentary rocks that contain this weather most quickly?
A: Rocks that contain calcite.

12. Question # 11
Q: What type of climate has the fastest rate of weathering?
A: Alternating hot and cold climates.

13. Question # 12 Q: What is crop rotation?
A: Farmers plant one type of crop one year and a different type of crop the next. Crop rotation stops erosion in its early stages.

14. Question # 13
Q: What are the 3 major types of landforms that are a result of weathering & erosion?
A: Mountains, plains, plateaus

15. Question # 14 Q: Name at least 2 of the 4 soil conservation methods.
A: contour plowing, strip-cropping, terracing, crop rotation.

16. Question # 15 Q: How does gravity affect erosion?
A: Creates mass movements such as creep, mudflows, slump, landslides, & solifluction.

17. Question # 16 Q: What are soil horizons?
A: A horizontal layer of soil that is clearly different from the layers above and below it.

18. Question # 17 Q: What is oxidation?
A: Process by which elements combine with oxygen. (Type of chemical weathering).

19. Question # 18 Q: What is differential weathering?
A: The process by which softer, less weather resistant rocks wear away at a faster rate than harder, more weather resistant rocks do.

20. Question # 19
Q: Formations of potholes in streets during severe winters is what type of weathering?
A: Mechanical

21. Question # 20
Q: Halite in rocks dissolving in water is an example of what type of weathering?
A: Chemical

22. Question # 21 Q: What is erosion?
A: The products of weathering are transported.

23. Question # 22 Q: What are the four agents of erosion?
A: Gravity, wind, glaciers, and water.

24. Question # 23
Q: What is a loose mixture of rock fragments and organic material that can support growth of vegetation called?
A: Soil

25. Question # 24
Q: Which would you expect to have a faster rate of weathering, mountainsides or flat land.
A: Mountainsides

26. Question # 25 Q: What is sheet erosion?
A: Process by which water flows over a layer of soil and removes the topsoil.
