Answer 1

Shores are influenced by the topography of the surrounding landscape, as well as by water induced erosion, such as waves. The geological composition of rock and soil dictates 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 storm beach is a beach affected by particularly fierce waves, usually with a very long fetch. The effect is most often a very steep beach (up to 45°) made out of shingle or occasionally sand. The shingle variety usually has an obvious grading of pebbles, from large to small, along the beach.

A particularly famous textbook example is the 18-mile long Chesil Beach in Dorset, England. It is also a tombolo connecting the Isle of Portland to the mainland west of the resort of Weymouth.
