Effects Of Waves, Currents, Tides,

  1. 1. Effects of Waves, Currents, Tides, and Storms of the Ocean Shore Zone
  2. 2. Effects of Waves <ul><li>On Beaches waves can wear away the land (erosion). </li></ul><ul><li>Waves can also deposit sand along the shore (deposition). </li></ul><ul><li>If they come in on an angle they can move sand along the coast. </li></ul><ul><li>For Barrier Islands waves can deposit sand on the beaches. </li></ul><ul><li>Also, waves can change the shape of the barrier islands. </li></ul><ul><li>Waves can deposit sand in estuaries </li></ul>
  3. 3. Effects of Currents <ul><li>Longshore currents along the shoreline can move sand from one location to another. </li></ul><ul><li>On barrier islands currents can move sand from one end of the island to the other. </li></ul><ul><li>Ocean currents can change the shape of the opening of an inlet opening. </li></ul>
  4. 4. Effects of Tides <ul><li>On beaches tides can bring in sand, shells, and ocean sediments at high tide and leave them behind when the tide goes out. </li></ul><ul><li>In estuaries, at high tide ocean water brings in sediments and sea life that feed and nourish life. </li></ul><ul><li>The amount of water in inlets changes with the tides. </li></ul>
  5. 5. Effects of Storms <ul><li>Storms affect the movement of water, therefore affecting the ocean shore zone. </li></ul><ul><li>Storms will often intensify the affects of the waves, currents, and tides. </li></ul><ul><li>Storms often bring increased winds resulting in erosion and deposition. </li></ul>
