  1. BY: Yonase Kidane and Brodie Hughes COASTAL Environments

  2. EROSION • -HYDRAULIC PRESSURE: • Compression of air and water • Causing cracks through • Increasing pressure • ABRASION (CORRASION): • When waves throws rocks colliding into the cliff causing it to break down and erode. • ATTRITION: • Rocks colliding within each other causing it tto break up into smaller peices

  3. Wave Pounding and Corrosion Wave Pounding: Immense force of waves causing the cliffs to weaken. Corrosion: The acid in water causes the cliffs to erode

  4. BY VAI CAVES, ARCHES, STACKS AND STUMPS

  5. Holes inside rocks by erosion causes it to become bigger and bigger until an arch is created. CAVE

  6. ARCh Arch: A large gap in a cliff created by erosion. Stack: When a part of the cliff grows too big to withhold it’s pressure and weight and breaks.

  7. STACK Stack: When the weight above exceeds what the arch can sustain and collapses causing a stack to remain Stump: The erosion made on stacks causing it to erode leaving a stump

  8. BLOWHOLE Created as sea caves grow landwards and upwards into vertical shafts and expose themselves towards the surface
