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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

4 - $400 n What is a looping bend in the path of a lowgradient stream called? n meander

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

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

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

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

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

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

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