| Frage | Antworten |
| Constructive Waves | -Long Waves -Strong Swash -Weak Backwash |
| Destructive Waves | -Result of stormy activity -Waves break from a considerable height -Strong swash -Strong backwash |
| Attrition | Rocks and pebbles collide reducing the size of the material and smooths edges |
| Hydraulic Pressure | -Lack of beach materials causes cliffs to take force of the waves breaking -Force air into the joints this compression causes rocks to loosen |
| Abrasion/Corrasion | High energy allows waves to carry sediment and hurl it against the cliff face |
| Slumping | Sub-aerial processes attack the cliff top and is when the weak rocks (clay/chalk) become saturated the weight |
| Promontory Land | Highland area jutting out to sea (Headland) |
| How is a stack formed? | -High wave energy creates a promontory piece of land -Cave/Arch -Weight causes headland to fall leaving a solitary piece of rock |
| Swash-aligned Beaches | -Waves approach parallel to the beach and the swash and backwash move sediment up sand down the beach -Storms can result in offshore bars |
| Drift-aligned Beaches | -Waves approach the coast at an angle -Long-shore drift -Groynes can help but cut off supply further down |
| Tombolo | Deposition of sediment joining the mainland to an island |
| Spits | Depositional feature -Wave direction causes a bending (finger like) structure |
| SMP | Shoreline Management Plan |
| ICZM | Integrated Coastal Zoning Management |
| Hard Engineering | Man-made structures put to prevent erosion to the coastline -Sea wall/Groynes/Rock Bund/Gabions/Revetments/Offshore bars |
| Managed Retreat | -Abandoning existing defences and allow flooding -Defences implemented further in land |
| Soft Engineering | Work with natural processes to preserve the coastline -Replenishment/Reprofiling |
