Waves
1. Explain the movement of water molecules within a wave.
- The water molecules move in circles and smaller when it gets in more depth
2. What do waves transmit across the sea?
- energy
3. Explain wave anatomy (make sure to label all parts)
- The parts are the wavelength, amplitude, crest, trough, and the height.4. What are most waves generated by? Explain.
- Most waves are generated by wind. Waves in the ocean are produced by wind moving over the water.
5. When do waves reach their maximum size?
- Waves reach their maximum size when they match the winds speed
6. Where are the largest waves on earth found? Why?
- The largest waves on earth are found on the outstretch between Antarctica and the Indian Ocean.
7. What is a wave train? What happens when there is interference of wave trains?
- Wave train is a group of wind driven in deep water, and develops into swells. When there is an interference of wave trains, it can produce a confused highly irregular sea.

. What is a rouge wave? How are they created? How big can they get?
- Rogue wave is a wave focused on wave trains and currents to produce a large wave. They can reach up to 100ft. and cause many shipwrecks.
9. What happens to waves in shallow water? Explain.
- When waves move into shallow water, it's behavior changes dramatically. Waves move into shallow water, because the water molecules come into contact with the seafloor.
10. What is swash? What does it do? How is it involved in erosion?
- Swash is when waves roll up and down the beach shore in foaming sheets of water. Swash is involved in erosion by the waves which are caused by the wind and generates strong currents.
11. What is a tsunami? Explain how they are different than wind generated waves.
- A tsunami is the largest and strongest wave on earth. Tsunami is different from a generated wind, because they travel very fast, low height, and the wave crests are miles apart.
12. What are some of the causes of tsunamis? Explain.
- Causes of tsunamis are underwater landslides, volcanic eruptions, asteroids falling into the sea, and mostly caused by earthquakes.
Global Impact
1. How can we generate electricity from wave power? Explain.
- We can generate electricity from wave powers by, relying on the movement of the waves to turn the turbine for electricity.
2. How much possible electricity could wave power generate?
- Wave power can generate electricity two times the world's current electricity.
3. How many people have been killed by tsunamis?
- One million people in history died from tsunamis.
4. What can be done about tsunamis to help protect people and property?
- To help protect people and property by installing warning systems, and rebuild coastal barriers.
DO: Activities- Breaking Waves
Tsunami Warning Systems
1. Describe the different types of warning systems that are in place for tsunamis (including animals, people and instincts).
- The types of warning systems for tsunami are surface buoy, button pressure recorder, sensors, DART System, tsunami evacuation route, tsunami hazard zone, and evacuation shelter.
