What’s going on ?

Lesson Outcomes To be able to define different types of erosion, and explain how they shape the coastline. By the end of the lesson you: MUST be able to define the different types of erosion. SHOULD be able to explain how this shapes the coastline. COULD begin to explain how features of erosion are formed.

How do waves shape the coastline? There are 4 types of coastal erosion: Abrasion - Bits of rock and sand in waves grind down cliff surfaces like sandpaper. Attrition - Waves smash rocks and pebbles on the shore into each other, and they break and become smoother. Hydraulic action - Air may become trapped in joints and cracks on a cliff face. When a wave breaks, the trapped air is compressed which weakens the cliff. Solution - Acids contained in sea water will dissolve some types of rock such as chalk or limestone.

What features do we get?

Features Dominoes Complete the features dominoes . Each domino has a key word and definition on it, you have to match the key word with its definition on another domino.

Coast Headland Crack Cave Arch Stack Stump Erosion Weathering Where the land meets the sea An outcrop of coastline A small opening in the cliff caused by erosion A large crack in the cliff that is big enough to walk into A cave that has eroded right through the headland The roof of an arch collapses, leaving a pillar of rock The stack collapses, leaving a smaller amount of rock The wearing away of rock material The breakdown of rock material Coast Headland Crack Cave Arch Stack Stump Erosion Weathering

Your task is to create a coastal feature with play-doh! Model features Your task is to create a coastal feature with play-doh! Create your landform on a piece of paper so you can label it, You need to explain how it was formed.

Include: Name of the landform (E.g. Arch) What erosional process is acting on it (think back to your Kung Fu)
