Abrasion

These rocks were rubbed away by abrasion. Abrasion is when waves bash against rocks, breaking pieces off them and then wearing those pieces down to be smoother and rounder. They are known as pebbles.

Page 2: Coastal processes2

Rocks are eroded by attrition. Attrition is when waves bash against cliffs and erode it away.

Page 3: Coastal processes2

This is also attrition. The waves have caused a hole in the cliff. The hole can be called an arch.

Page 4: Coastal processes2

This sculpture was formed by waves picking up sand particles and throwing them against the cliff. Do you see the different angles on the sculpture? That is because the wind was blowing in different directions.

Page 5: Coastal processes2

This was also formed by waves picking up sand particles and throwing them against the cliffs. I also put this picture in to tell you that it is February here and the sky is blue.

Page 6: Coastal processes2

This is also abrasion.

Page 7: Coastal processes2

This edge of this sand was washed away by the waves.

Page 8: Coastal processes2

Waves have eroded these rocks into layers. The waves crash against the rock with such a force, it erodes away the rock, layering it.

Page 9: Coastal processes2

These pillars mark where the eroding has been.

Page 10: Coastal processes2

This is a close – up of the pillar.

The pillars are numbered so that people can record the erosion. E.g. Number 470 is closer to the sea than it was 3 weeks ago because the sea has eroded the cliff away a lot.
