WAVE ENERGY THE WIND THAT COMES FROM SEVERE WINTER STORMS AND SUMMER HURRICANES GENERALLY PRODUCES THE LARGE WAVES THATCAUSE SHORELINE EROSION.

WAVE EROSION. How do waves form? By wind that blows across the water’s surface. The wind causes water particles to move up and down as a wave goes by.

Coastal Features Headlands and Bays A headland is an area of land which juts out to sea and is surrounded by sea on three sides. Headlands form in coastlines.

Coastal Regions. Waves cause coastal features such as Arches, Caves and Inlets. Headlands (shorelines that project into the ocean) erode much faster compared.

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 rock 2. erosion- the movement of weathered rock 3. 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 Energy The 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 Erosion What 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 Cliffs Most Dramatic Sea Cliffs in the World |

The Stages of Erosion

Cracks Become Caves NOVA | How Caves Form NOVA | How Caves Form Cave formation on Ballintoy coast, Ireland

Caves Become Arches Bob's Arches - Sea Arches

Arches Become Stacks Spectacular Sea Stacks
