5 Multiple Choice Questions

  1. 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)
  2. path water takes from ocean, evaporation, precipitation, surface flow, transpiration, groundwater flow, and return to ocean
  3. distance per unit time (i.e m/sec); varies greatly within and between streams
  4. larger material that moves along the bottom of the stream
  5. base level, gullies/canyons/gorges, superposed streams, antecedent streams, steam terraces, incised meanders

5 True/False Questions

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

          

  2. superposed streamsi.e. Delaware river water gap; stream cuts into pre-existing geologic structures such as anticlines

          

  3. braided streamsresult when stream is fully loaded with sediment

          

  4. stream terracesremnants of floodplains from when stream was flowing at a higher level; flat surfaces above current stream valley / formed by slow uplift of land surface over which meandering streams with floodplains are flowin

          

  5. alluvial fansform when the stream flows into larger body of calm water and sediment load is deposited
