Final Jeopardy

2. 1 - $100 What are 3 ways landmasses of the earth degenerate?
Weathering, mass wasting and erosion

3. 1 - $200 What are the 2 types of weathering?
Chemical and mechanical weathering

4. 1 - $300 What factors influence the rate of chemical weathering?
Kinds of minerals in rocks; climate, temperature, moisture, amount of exposed surface

5. 1 - $400
How much does water expand when it freezes? 9%

6. 1 - $500 What happens to rocks and soil when water freezes?
Breaks rocks into smaller pieces; cause frost heaving in soil;

7. 2 - $100
What is the accumulation of rock debris at the base of a cliff called?
talus

8. 2 - $200
True or False? Weathering reduces the orderliness of the materials in the original rock
True

9. 2 - $300 What are the components of soil?
Sand , silt or clay combined with decayed organic material (humus)

10. 2 - $400
What are the layers of soil called?
horizons

11. 2 - $500
What is the downhill movement of large masses of soil or rock under the influence of gravity called?
Mass wasting

12. 3 - $100 What factors influence the rate to mass wasting?
Slope of the land; vegetation of the area and presence of water.

13. 3 - $200
What rapid mass wasting involving detached pieces of bedrock called?
rockslide

14. 3 - $300 What are the 3 kinds of debris slides?
Earthflows, mudflows and avalanches

15. 3 - $400
What is the rate of drop of a stream called?
gradient

16. 3 - $500
What is the ultimate base level for most streams?
Sea-level

17. 4 - $100
What are smaller streams that flow into larger streams called?
tributaries

18. 4 - $200
What are streams that result from the subdivision of a larger stream called?
distributaries

19. 4 - $300
What is the main difference in energy contained in high-gradient and low-gradient streams?
More energy in high-gradient stream because its water is flowing faster.

20. 4 - $400
What is a looping bend in the path of a low-gradient stream called?
meander

21. 4 - $500
What form of erosion occurs when water dissolves minerals and removes them from the soil?
Solution erosion

22. 5 - $100 What is an alluvial fan?
Created when a high-gradient stream flows onto a level plain and deposits its load of sediment in a fanlike formation

23. 5 - $200
What is a delta?
Formed at a river’s mouth, where the river enters a large body of water.

24. 5 - $300
What confined body of water flows continuously or seasonally on the earth’s surface or underground.
stream

25. 5 - $400
True or False? Chemical weathering an result in both a change of composition and a change in shape?
True

26. 5 - $500 List 6 methods for controlling soil erosion
Cover crops (planting vegetation), crop rotation; contour plowing, no-till agriculture, strip-cropping, and terracing.

27. Final Jeopardy How are weathered rocks different unweathered rocks?
Weathered rocks are more rounded, pitted, and discolored compared to unweathered rocks.
