A headland, also known as a head, is a coastal landform, a point of land usually high and often with a sheer drop, that extends into a body of water. Erosion characterizes these high-energy environments, which are typically located on active margins with narrow continental shelves (on account of subduction). The coastline was all once straight and didn't have bit sticking The formation of the coastal landscape depends on many factors, including the type of rock these processes are acting on, how much energy is in the system, sea currents, waves, and tides.

A collapsed volcanic crater is flooded leaving a sheltered area. The outcome of this downward movement is apparent along shoreline cliffs where the sea currents hit the base of the cliffs and the dented slope to cause an ultimate collapse of the rock in the seawater.
