    INTERLOCKING SPURS
    • river @ source is small w/ limited energy; flows naturally from side to side, spurs become interlocking
  • | landforms
    WATERFALLS
    • common where there’s lots of VERTICAL EROSION_ happens where there’s resistant rock on softer rock
    1. when hard rock overlays a soft rock; the softer rock erodes faster
    2. this means the river UNDERCUTS hard rock, leaving an OVERHANG
    3. PLUNGE POOL forms below waterfall
    4. overhanging rock falls into plunge pool which erodes it & makes it bigger
    5. waterfall retreats backwards
