Geography (coasts)

• Gravitational pull forms waves
• ConstructI’ve waves create the beach and destructive waves break the beach down
• Weathering is the process of rocks breaking down due to diffe weather conditions
• Erosion effect the coast when it breaks down and erodes the cliff and beaches
• beaches are formed by the deposit of sediment from the sea which is carried by the wind
• spits are created by the wind blowing the current in a different direction
• headland are cliffs that stick out into the sea and are formed by erosion
• bays are a body of water surrounded by land
• caves,arches,stacks and stumps form from erosion
• the main threats to facing coastlines are global warming and factorise that lead the co2 i to the sea which causes sea levels rising,storm surges which lead to losing land
• coastlines can be managed with rock armour,sea walls ,groynes sand others
• groynes are wooden structures used to trap sediment so it doesn't move down the beach
• rock armour is large rocks placed on top of each other to protect against waves
• seawalls are built along the shoreline to prevent flooding
• hard engineering is where man made materials are used to control coastal change
• soft engineering is when natural processes are allowed to happen but they are controlled by humans
• beaches are formed by longshore drift
