  • Erosional River Landforms
    • Waterfalls are found in the Upper Course of a river
    • Waterfalls forms when a river flows over an area of hard rock to and area of soft rock.
      • The soft rock is eroded more than the hard rock; this creates a 'step' in the river.
        • A steep drop is eventually created which creates a waterfall.
      • The hard rock eventually erodes and become undercut that makes it unsupported and collapses
        • The collapsed rocks are swirled to the bottom where they erode due to corrasion; this create deep plunge pool.
          • Overtime, the constant undercutting will cause more collapses. The waterfall will move back up the channel, leaving behind a gorge.
    • Interlocking Spurs:
      • As rivers erode they create steep sided, V-shapes vallleys
        • Rivers end up winding around hils and stick to their paths.
          • The hills that interlock with eachother as the river winds around them are called interlocking spurs.
  • Overtime, the constant undercutting will cause more collapses. The waterfall will move back up the channel, leaving behind a gorge.
