5 Matching questions

  1. erosion
  2. discharge
  3. alluvial fans
  4. gradient
  5. velocity
  1. a lobe-shaped deposits similar to deltas but adjacent to highlands; typically arid to semi-arid conditions
  2. b 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
  3. c distance per unit time (i.e m/sec); varies greatly within and between streams
  4. d physical removal of particles by either abrasion, movement, or dissolution
  5. e 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 Multiple choice questions

  1. topographic feature separating water sheds
  2. total area that drains into a particular stream
  3. 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
  4. gradient, velocity, discharge
  5. 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 True/False questions

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


  2. incised meanderspreviously established meanders in area that is being uplifted-
    form from deep downcutting of meandering stream through hard bedrock. Shape of meanders is
    preserved in river canyon shape


  3. dissolved loadsmaller 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


  4. braided streamsresult when stream is fully loaded with sediment


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