5 Written questions

5 Matching questions

  1. discharge
  2. suspended load
  3. gradient
  4. alluvial fans
  5. meandering streams
  1. a point bars, oxbow lakes
  2. b smaller particles that move with the water- too small to settle out. Whether a particular particle is transported or not and how it is transported depends on the energy level of the stream and the size and shape of the particle
  3. c slope over which the stream flows (i.e. if the headwaters are at 1000 meters and the stream flows 500 km to the sea, the gradient is 1000m/500km= 2m/km)
  4. d lobe-shaped deposits similar to deltas but adjacent to highlands; typically arid to semi-arid conditions
  5. e total volume of water moving past a particular point over a given period of time (to calculate, need the channel dimensions to calculate area and the stream velocity: Q (discharge)= V* A

5 Multiple choice questions

  1. larger material that moves along the bottom of the stream
  2. direct rain, surface run-off, soil moisture, and groundwater
  3. base level, gullies/canyons/gorges, superposed streams, antecedent streams, steam terraces, incised meanders
  4. i.e. Delaware river water gap; stream cuts into pre-existing geologic structures such as anticlines
  5. bed load, suspended load, dissolved load

5 True/False questions

  1. base levellarger material that moves along the bottom of the stream

          

  2. floodplain depositsgradient, velocity, discharge

          

  3. divideform when the stream flows into larger body of calm water and sediment load is deposited

          

  4. incised meandersresult when stream is fully loaded with sediment

          

  5. antecedent streamsstream cuts deep channel as land is uplifted (i.e. stream channel is maintained as an anticline is forming resulting in the stream cutting through the structure instead of following beside it)
