Depositional coastal landforms
Lesson details
Learning outcome
I can explain depositional processes and describe the coastal landforms they create.
Key learning points
- Longshore drift is the lateral movement of sediment across the beach through swash and backwash.
- Longshore drift creates depositional landforms such as spits, bars and tombolos.
- Spits are long narrow ridges of sand or shingle which project from a coastline into the sea.
- Salt marshes may form behind spits, as these are low energy zones.
- Spits can change direction due to the prevailing wind, which makes them curve into a hook.
Keywords
Deposition - when material such as sand, mud or rocks is dropped by the water that was carrying it
Transportation - transportation is when water moves sand, mud and rocks
Swash - when a wave rushes up the beach
Backwash - when the water from a wave retreats back into the sea
Sediment - material that is moved by water or air and settles in another place
Common misconception
That the direction of the prevailing wind is the direction that the wind is blowing in at any particular time.
The prevailing wind is wind from a particular direction that is most frequently experienced in a location. Winds can come from other directions, especially in stormy conditions, but they are not the same as the prevailing wind.
Teacher tip
Use internet software to look at satellite images of spits and other depositional landforms around the UK, and in other places around the world. Ask students to compare them and talk about similarities and differences. This will help them to identify the features of the landforms.
