COASTAL Environments


Erosion
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


Wave pounding and corrosion
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


Caves arches stacks and stumps

BY VAI

CAVES, ARCHES, STACKS AND STUMPS



ARCh bigger until an arch is created.

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.


Stack
STACK bigger until an arch is created.

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


Blowhole
BLOWHOLE bigger until an arch is created.

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