The coastal zone: key processes - BBC Bitesize.
Seawater motions are the result of waves, tides, and currents. Ocean movements are the consequence of many separate factors: wind, tides, Coriolis effect, water density differences, and the shape of the ocean basins.
Caves, arches, stacks and stumps Weathering and erosion can create caves, arches, stacks and stumps along a headland. Caves occur when waves force their way into cracks in the cliff face.
Wave types - constructive and destructive. When the wind blows over the sea, it creates waves. The size and energy of the wave depends on certain factors.
IntroductionThe extent to which the shape of a beach or coast is altered depends largely on the action of waves upon it. Waves can be gentle and infrequent or larger, more frequent and more powerful.The formation of waves and their size and shape is a result of the exchange of energy from wind blowing over the sea. The longer the wind blows for, and the greater the distance it blows over, the.

Lake - Lake - Effects of wave and current action: In a lake’s early stages of existence, its shore is most susceptible to changes from wave and current action. As these changes occur, there is a tendency over time to an equilibrium condition—a balance between form and processes that depends upon the nature of the materials present (e.g., the size of sand and gravel present).
Wave energy is energy harnessed from the wavesof the ocean. Waves are formed by wind moving across the surface of the ocean. A large amount of energyis stored in waves. A wave power device.
