Lesson details
Key learning points
- Climate (seasonality, storm frequency, prevailing winds) affects the rate of erosion along coastal landscapes.
- Marine processes (destructive waves) affect coastal landscapes and the rate of coastal retreat.
- Sub-aerial processes (mass movement, weathering) affect coastal landscapes and the rate of coastal retreat.
Keywords
Erosion - the wearing away of rocks along the coastline
Constructive wave - low-energy waves that result in the buildup of sediment along the coastline
Destructive wave - high-energy waves that result in the removal of sediment along the coastline
Weathering - the breaking down or dissolving of rocks through plants, animals and weather
Mass movement - downhill movement of sediment due to gravity
Common misconception
Swash is when a wave moves down the beach to the sea and backwash is when a wave moves up the beach from the sea.
The swash is the movement of the wave from the sea to the beach which brings sediment with it. Whereas the backwash is the movement of the wave from the beach to sea.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
