Shores are influenced by the topography of the surrounding landscape, as well as by erosion caused by water, such as waves. The geological makeup of rock and soil controls the type of shore which is created. Erosion of sedimentary soils can make a sandy or pebbly shore, usually called a beach.
A shore includes the intertidal zone that is alternately exposed and covered by waves and tides.
A shore will often have a lighthouse on it to help ships in the sea.
