The work of waves

The work of wavesWaves erode

Waves transport

Waves deposit

Waves do three main jobs:

1. ………………………………

2………………………………

3. ………………………………

1. Waves Erode•Hydraulic action – as waves hit rocks, air is trapped and compressed in the cracks and when waves retreat, air expands violently. This breaks off bits of rocks (mini explosions)

•Abrasion – waves throw rocks against cliffs

•Attrition – rock fragments are smashed against each other and further break down

•Solution – some minerals in rocks slowly dissolve in water

Mini Task:In your exercise books draw an annotated diagram to explain the process of longshore drift

Dance Routine for Longshore Drift! Watch from 2 mins up to 4mins

3. Waves Deposit

• Material is dropped by waves once they lose energy as they roll up a beach,

• Or where there is an obstacle.

• Or where there is shelter from the wind.

TASK

• In small groups create your own dance routine that shows the processes of;– erosion, – transportation and – deposition.

• The best group will get a merit and will be filmed for the Geography blog.
