5 Written questions

5 Matching questions

  1. braided streams
  2. gullies, canyons, and gorges
  3. base level
  4. divide
  5. bed load
  1. a down cutting occurs when stream has more energy than is required to carry its sediment load
  2. b larger material that moves along the bottom of the stream
  3. c stream will cut channel down to base level (ultimate base level is sea level); local base level could be larger than stream or lake
  4. d result when stream is fully loaded with sediment
  5. e topographic feature separating water sheds

5 Multiple choice questions

  1. distance per unit time (i.e m/sec); varies greatly within and between streams
  2. braided streams, meandering streams, floodplain deposits, deltas, alluvial fans
  3. i.e. Delaware river water gap; stream cuts into pre-existing geologic structures such as anticlines
  4. 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. total area that drains into a particular stream

5 True/False questions

  1. hydrologic cyclepath water takes from ocean, evaporation, precipitation, surface flow, transpiration, groundwater flow, and return to ocean

          

  2. flow characteristicslevees

          

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

          

  4. streams - sources?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. transport of sedimentslope 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)
