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. Although a beach is a synonym for a shore, the term typically refers to shores which are sandy or pebbly, which can be produced by erosion of sedimentary soils.
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.
