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.
