  • FORMATION OF WATERFALLS
    • 1
      • The soft rock  erodes more quickly, undercutting the hard rock.
        • 2
          • The hard rock is left overhanging and because it isn’t supported, it eventually collapses.
    • 3
      • The fallen rocks crash into the plunge pool. They swirl around, causing more erosion.
        • 4
          • Over time, this process is repeated and the waterfall moves upstream.
            • 5
              • A steep-sided gorge is formed as the waterfall retreats.
