PRESENTATION OUTLINE
Beach - a pebbly or sandy shore, especially by the ocean between high- and low-water marks.
Wave - a long body of water curling into an arched form and breaking on the shore.
Abrasion - the process of scraping or wearing away.
Wave Refraction - when waves approach a straight shoreline at an angle.
Longshore Transport - the process responsible for the movement of sand and sediment along the coastline.
Wave-cut Cliff - the steep edge along the side of a rock face, which was eroded by the waves.
Wave-cut Platform - the narrow flat area often found at the base of a sea cliff or along the shoreline of a lake, bay, or sea.
Sea Arch - a natural arch or bridge made of stone that has been created when water wears away the underside of a rock, leaving just the top behind.
Sea Stack - a column of rock standing in the sea, remaining after erosion of cliffs.
Spit - an extended stretch of beach material that projects out to sea and is joined to the mainland at one end.
Sandbar - a long, narrow sandbank, especially at the mouth of a river.
Tombolo - a bar of sand or shingle joining an island to the mainland.
Barrier Islands - a long narrow island lying parallel and close to the mainland, protecting the mainland from erosion and storms.
Groin - a long, narrow structure built out into the water from a beach in order to prevent beach erosion or to trap and accumulate sand.
Breakwater - a barrier built out into a body of water to protect a coast or harbor from the force of waves.
Seawall - a wall or embankment erected to prevent the sea from encroaching on or eroding an area of land.
Beach Nourishment - the process of dumping or pumping sand from elsewhere onto an eroding shoreline to create a new beach or to widen the existing beach.
