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


Coastal environments

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

CAVE


Coastal environments

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.


Stack

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


Blowhole

BLOWHOLE

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