Weathering and Erosion

When you think of a beach, what images pop into your mind?

What makes a beach/shoreline?

1. weathering- the breakdown of rock2. erosion- the movement of weathered rock3. deposition- the dropping off of weathered rock

How does the process start?What do we need to begin the process of

weathering, erosion, and deposition?Wave EnergyThe stronger a wave is, the more W, E, and D can

take place.

Putting it all together.Waves break down rocks along shorelines.The stronger the waves, the more weathering

occurs.Waves transport weathered rock particles to

different locations.Waves deposit the rock particles along shorelines,

forming beaches.

Coastal ErosionWhat are the 4 ways that the sea erodes the

coast – the different types of erosion?

Don’t forget, weathering is also

at work on the coastline as well

THE LANDFORMS

What are they?How are they formed?

Headlands and Bays

Some Headlands

And Some Bays

Headlands and Bays Together

How are they formed?

Its all about differential erosion!!!!!!!!

Cliffs, Caves, Arches and Stacks.

The Headland is Attacked!!!

Besides beaches, what other features can waves create?

Sea CliffsMost Dramatic Sea Cliffs in the World |
