Waves
Ocean waves are caused by wind and transfer energy through water, but do not transfer water from place to place. Key characteristics of waves include wavelength, amplitude, height, and period. Wave movement involves an orbital pattern, with energy moving through water in a circular motion. Near shore, waves begin to break as their movement becomes disrupted. Breaking waves can come crashing ashore. Some surfers seek out large storm waves for challenges they present. There is potential to harness wave power as an energy source.

Ocean Currents, Waves,and Tides • Ocean currents, waves, and tides all influence water movement in the ocean • Ocean currents are different from ocean waves – Water moves (sort of like a river in the ocean) from place to place in the ocean as a result of ocean currents – Energy moves through the ocean as a result of ocean waves
- 4. Ocean Waves • Causedby the wind • Energy moves through the water, but the water does not move!!!! • http://eric.boissard.free.fr/waves.html • (remember, things are different near shore when waves start to “break”. More on this later)
