Headlands and bays form on discordant coastlines, where bands of rock of alternating resistance run perpendicular to the coast. Parts of the headland that jut out into the water slowly get eroded over time by the mechanical energy of winds and waves. First, it's important to understand the different types of rock that comprise a headland because not all rocks will erode at the same rate.

Differential erosion creates headlands and bays, in which rocks along the coast are formed in alternating bands of various rock types, such as sandstone and clay, that meet the coast at right angles. This leaves a section of land jutting out into the sea called a headland. Coastlines where the geology alternates between strata (or bands) of hard rock and soft rock are called discordant coastlines. 97 mph Fuel economy on a Can-Am Ryker 900? It is a type of promontory. Cape Sebastian and Humbug Mountain are ex-amples of rocky headlands in this area. On a discordant coastline the softer rock will be rapidly eroded away, leaving the harder rock to form headlands. 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. Measurements by geologists confirm that the Wall's surface is wearing away at an almost unbelievably fast pace; in some places, an inch or more is removed from the surface each year.
