Headlands are land bordered by either salt or fresh water on three sides; these lands are referred to as capes. Headlands and bays are features of coasts that are formed. In lower-energy pocket beaches, sediment transport is not able to carry sediment downshore except during increased wave, wind, and storm activity. Another type of weak zone is formed where dissimilar types of rocks are inter-bedded and one is weaker than the other. These areas are often subjected to changes in environmental forces such as cyclones, tsunami, earthquakes, and climate changes. With prolonged erosion, sea arches may collapse to form sea stackssteep pillars of rock a short distance from the mainland.

A number of stages are involved: All rocks have lines of weakness; the sea and its waves use hydraulic action, abrasion and solution to erode along any lines of weakness. Tidewater glaciers are usually bright whitish-blue due to ice density and the tendency of calving (breaking into the sea). The largest and most common caves are those formed by chemical reaction between circulating groundwater and bedrock composed of limestone or dolomite.
