PRESENTATION OUTLINE
Beach- An accumulation of sediment found along the landward margin of the ocean or a lake.
Wave- the movement of energy through a body of water
Abrasion- The grinding and scraping of a rock surface by the friction and impact of rock particles carried by water, wind, and ice.
Wave Refraction- A change in direction of waves as they enter shallow water. The portion of the wave in shallow water is slowed, which causes the waves to bend and align with the underwater contours.
Long shore Transport- Movement of sand along a beach
Wave cut Cliff- A seaward-facing cliff along a steep shoreline formed by wave erosion at its base and mass wasting.
Wave cut Platform- A bench or shelf along a shore at sea level, cut by wave erosion.
Sea Arch- An arch formed by wave erosion when caves on opposite sides of a headland unite.
Sea Stack- An isolated mass of rock standing just offshore, produced by wave erosion of a headland.
Spit- An elongate ridge of sand that projects from the land into the mouth of an adjacent bay.
Sandbar- sand that has been deposited on the shallow, underwater slope along a shoreline by the repetitive wave action on a sandy beach
Tombolo- A ridge of sand that connects an island to the mainland or to another island.
Barrier Islands- A low, elongate ridge of sand that parallels the coast.
Groin- A short wall built at a right angle to the seashore to trap moving sand.
Breakwater- A structure protecting a nearshore area from breaking waves.
Seawall- Process in which large quantities of sand are added to the beach system to offset losses caused by wave erosion. Building beaches seaward improves beach quality and storm protection.
Beach Nourishment- Process in which large quantities of sand are added to the beach system to offset losses caused by wave erosion. Building beaches seaward improves beach quality and storm protection.
