1. Ocean Movements

2. Ocean Movements Oceans are never motionless
The most obvious movements are waves
These are normally generated by wind

4. Wave Characteristics
Crest
Wavelength
Trough
Wave height

5. Wave Height This depends on 3 things
Wind speed, wind duration, and fetch
Fetch is how big the body of water is that the wind crosses

6. Breaking Waves
When waves approach the shore they lose energy because of friction with the ocean bottom
This friction causes the wave to slow down
Collapsing waves are called breakers
