Coast

• Waves continuously erode and shape coastlines over time.
• Waves are caused by wind blowing over the surface of the ocean. The energy from the wind causes ripples which grow bigger as they travel further away from the source of the wind. These become waves that can carry large amounts of energy across the oceans.
• Waves are formed by wind blowing over the surface of the sea or ocean. The force of the wind causes ripples to form which grow larger as they move away from the source of the wind.
• Coastal erosion occurs when waves break on the shoreline, causing rocks to be moved along the beach or cliffs to collapse into the sea.
• Coastal erosion occurs when waves break on the shore, causing sediment to be moved along the beach or carried out into deeper water.
• Estuaries form where rivers meet the coast and deposit sediment, resulting in areas of low topography that are flooded by tides.
• Coastal sand dunes form where there is a sufficient supply of sand and the winds transport and deposit the sand on the shoreface.
• The coast is the area where land meets water
• The coast is the area where land meets water
• The coastal zone is the area between high tide mark and low tide mark.
• Coastal processes include wave action, weathering, mass movement, and deposition.
• Beaches are formed by waves depositing sediment on land.
• There are three main types of waves: transverse waves, longitudinal waves, and surface waves.
• The height, speed, length, and direction of waves depend on factors such as wind strength, distance travelled, water depth, and wave period (the amount of time between two successive crests).
• The height, speed, length, and direction of waves depend on factors such as the strength of the wind, distance travelled, depth of water, and direction of wave propagation.
• Wave height is determined by the amount of energy transferred into the wave by the wind.
• The movement of sediment is an important process in coastal erosion. Sediments such as sand, gravel, and pebbles are carried along the seabed by currents generated by wave action.
• Beaches are areas where sediment has been deposited by waves breaking against the shoreline.
