1. Geologic Features of the Ocean Shore Landforms Unit Indicator 5-3.4 5 th Grade

2. Beaches Waves: Can wear away land and expose rocky shore Can deposit new sand Currents: Move sand from one location to another Tides: Bring in sand, shells, and ocean sediments

3. What are beaches?

4. Effects of tides on Shore Line These logs were washed ashore by tides after a storm. What are some things that you have seen on the beach before that are an effect of tides on our shore line?

5. Barrier Islands Waves: Deposit sand on beaches and change the shape of barrier islands Currents: Move sand from one end of the island to the other Barrier Island before and after a hurricane.

6. What are barrier islands?

7. Estuaries All rivers flow into the ocean. The area where a river meets the ocean is an estuary. Waves: Deposit sand in the estuaries At high tide, ocean water brings in sediments and sea life that feed and nourish life in the estuary.

8. What are estuaries?

9. Inlets Tides: As tides change the amount of water will change Currents and Storms: Change the shape of an inlet opening Inlet opening before and after a hurricane.

10. Important Points Currents along the shoreline can move sand from one location to another. These are known as longshore currents. Barrier Islands are naturally occurring and function to protect the mainland from the effects of waves on its shore. Estuaries have a mixture of freshwater and saltwater. Inlets are the water filled spaces between the barrier islands.
