COASTS

• Constructive waves are more peaceful, harmless, are spread far from each other and have a strong swash but a weak backwash
• Destructive waves are more aggressive looking, taller and have a strong back wash but weak swash
• LONGSHORE DRIFT

  Longshore drift is when the wind pushes the waves at an angle. The swash carries the sand material along the beach and the backwash carries the material straight down
• STUMP FORMATION

  Water erodes at a cliff and cracks, that turns to a cave as the water erodes at the crack. The cave walls thin and weaken and that turns the cave into an arch. When the arch can no longer support itself, it falls creating a stack. The water erodes the base of the stack, creating a stump.
• Stump formation- what correlation it goes in

  cracks, caves, arches, stacks, stumps
• • Resistant and non-resistant rock meet the coast line.
  • Waves erode the rock at different rates
  • The non-resistant rock erodes faster creating a bay
  • The resistant rock erodes slower so it left jutting out at sea, creating a headland.
  • Inside sheltered bays, deposition occurs creating beaches
• HEADLANDS AND BAYS

  The water erodes the base of the headland, creating a wave cut notch at sea level. The notch deepens and the hangover cliff collapses, the cliff wall retreats. This process repeats over time, leaving a platform behind. We call that a wave-cut notch platform
