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.
