Stack
An isolated piece of rock detached from the mainland by wave erosion.
Wave-cut Notch

Wave-cut Platform
A gently sloping, rocky platform found at the foot of a retreating cliff and exposed at low tide.
Tombolo

Wave-cut Platform
Intertidal rock surfaces of low slope angle formed as a cliff retreats inland.
Beach
A coastal accumulation of varied types of sediment, usually of sand size or above.
Swash-aligned Beach
Wave crests arrive parallel to the coastline, creating a uniform shaped beach.
Drift-aligned Beach
Wave crests approach at an angle to the shoreline, encouraging drift of material from one end of the beach to the other.
Concordant Coastline
Rock types are laid down parallel to the coastline.
Discordant Coastline
Rock types are lard down perpendicular to the coastline, encouraging the formation of headlands and bays.
Sand Dune
