What you'll learn

Each question helps you build key knowledge and skills.

  • 1Waves are created by wind blowing over the sea, and their size depends on wind speed, duration and fetch, the distance of open water they travel across.
  • 2Erosion processes including hydraulic action, abrasion, attrition and solution gradually wear away the coastline, especially where rock is soft or heavily jointed.
  • 3Headlands and bays form on discordant coastlines where bands of hard and soft rock are eroded at different rates.
  • 4Longshore drift transports sediment along the coast in a zig zag pattern, caused by waves approaching at an angle driven by the prevailing wind.
  • 5Depositional landforms such as spits, bars and tombolos form where the coastline changes direction or where sediment supply is high.
