Rocky coasts may be composed of any rock type (i.e., sedimentary, igneous, or metamorphic) and are usually the site of complex tectonic landforms such as faults, folds, and igneous intrusions and extrusions. Depending on climate, topography, and amount of snowfall over time, tidewater glaciers may periodically experience rapid retreat, creating many large icebergs. The altering rate of erosion of hard and soft rock is known as differential erosion. Tidewater glaciers are usually bright whitish-blue due to ice density and the tendency of calving (breaking into the sea).
