5 Matching Questions

  1. gradient
  2. hydrologic cycle
  3. base level
  4. alluvial fans
  5. meandering streams
  1. a path water takes from ocean, evaporation, precipitation, surface flow, transpiration, groundwater flow, and return to ocean
  2. b point bars, oxbow lakes
  3. c lobe-shaped deposits similar to deltas but adjacent to highlands; typically arid to semi-arid conditions
  4. d 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)
  5. e stream will cut channel down to base level (ultimate base level is sea level); local base level could be larger than stream or lake

5 Multiple Choice Questions

  1. down cutting occurs when stream has more energy than is required to carry its sediment load
  2. bed load, suspended load, dissolved load
  3. levees
  4. direct rain, surface run-off, soil moisture, and groundwater
  5. remnants 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 True/False Questions

  1. depositionbraided streams, meandering streams, floodplain deposits, deltas, alluvial fans

          

  2. incised meanderslarger material that moves along the bottom of the stream

          

  3. geomorphologydistance per unit time (i.e m/sec); varies greatly within and between streams

          

  4. erosionphysical removal of particles by either abrasion, movement, or dissolution
