- Coasts
- What are the factors which infuence the waves?
- Swash, direction of the wash determined by the wind direction
- Backwash, movement of water, 90 degrees opposite the swash
- How do waves shape the land?
- Cliffs desolve in the sea water
- Hydralic Action, waves compress packets of air (in the cliffs) causing a crack to widen
- Abrasion, Eroded material breaking off the rock
- What are the processes that lead to the formation of a stack?
- Crack, the sea erodes some of the hard rock through hydraulic action.
- Cave, the sea eroded more rock to get a cave eroding through hydraulic action
- Arch, eroded fully through the cave, using hydraulic action
- Stack, the sea eroded through the arch making a stack
- Stump, sea eroded through the stack, making it fall and eroding until nothing is left
- What is longshore drift?
- the movement of sediment along the coastline in a zigzag motion
- What is a spit?
- A spit is a long, narrow finger of sand or shingle jutting out into the sea from land
- Untitled
- How do we prevent coastal erosion?
- Hard Engineering
- Human made structures that help manage coastal erosion
- Soft Engineering
- Adaptations that work with nature and manages coastal erosion
- Sea Wall
- A concrete wall which acts like a barrier that reflects the energy back into the sea
- Hard Engineering
- What are the factors which infuence the waves?
