A headland can also be much larger, forming a cape at one protruding end of an island or a continent. 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. Headlands form along discordant coastlines where bands of soft and hard rock outcrop at a right angle to the coastline (see image below). Some of these aerosol cans, such as engine enamel, are gasoline resistant, but the majority will not hold up, M stands for metre (length), K stands for kilogram (mass), and S stands for seconds (time) in the MKS system.

A flat coast is one in which the land gradually sinks into the sea. The constant erosion of rocky headlands may produce a variety of particular geomorphic structures, including sea arches and sea stacks. These are determined by geology, rates of erosion and beach profile. The primary characteristics of this landform are low-wave energy, strong offshore sediment influence, and a full continental shelf. This means that the bathymetry (the underwater elevation) of the ocean or sea bed also impacts the strength of waves. Bays are made up of soft rocks while headlands are made up of hard rocks. Badlands National Park features the unique topography characterized by sharply eroded buttes, gullies and ridges that has come to be known as badlands.
