1. What’s going on ?

2. 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.

3. 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.

5. What features do we get?

6. 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.

14. 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.

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