1. Waves NOAA OCEAN WAVESOCEAN WAVES Snowball Fight View Strategy

2. I. Anatomy of a Wave  Illustrate the wave to the right.  Identify and label the following parts of a wave  Crest  Trough  Wavelength  Wave height

3. II. Wave Formation & Movement A. What causes waves?  For the most part waves form from wind.

4. B. Wave Movement 1. Ocean waves are energy traveling along between the ocean and atmosphere. 2. Energy traveling through a medium (water) 3. Water does not move with the energy. Animation of Wave Motion

5. III. Specifics of Wave Motion A. Wave period the time between the passage of two wave crests (or troughs) at a fixed point. B. Wave Speed NOAA Ocean Waves: Measure a Wave

6. IV. Types of Waves 1. Deep-water waves 2. Shallow-water waves

7. A. Deep-water waves  Deep-water waves are waves that move in water deeper than one-half their length.

8. B. Shallow-water Waves 1. Water shallower than one-half of their wavelength. 2. Waves increase in height as they approach the shore when they begin to interact with the ocean floor. NOAA: Ocean Waves: Breaking waves

9. V. Tsunami  A giant ocean wave that forms as result of a geologic event. NOAA: Ocean Waves:  2004 Indian Ocean Tsunami  Tsunami Warning System

10. VI. Tides  Tides The periodic rise and fall of the water level in the ocean and large bodies of water  Tides are caused by the interaction between the Earth, the moon, and the sun.
