Questions
1. Explain the movement of water molecules within a wave.
> they move by going in a circle
2. What do waves transmit across the sea?
> waves transmit energy
3. Explain wave anatomy (make sure to label all parts)
> the parts are the wavelength, the amplitude, the crest, the trough, and the height
4. What are most waves generated by? Explain.
> waves are generated by wind, waves are produced by wind moving over the ocean
5. When do waves reach their maximum size?
> when they match the speed of the wind
6. Where are the largest waves on earth found? Why?
> empty stretch between Antarctica and the Indian ocean
7. What is a wave train? What happens when there is interference of wave trains?
> 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.
8. What is a rouge wave? How are they created? How big can they get?
> a wave focused on wave trains and currents to produce a large wave, they can reach 100ft
9. What happens to waves in shallow water? Explain.
> it's behavior changes dramatically, they go 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?
> 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.
> largest and strongest wave on earth, a 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.
> 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 power 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?
> 1,000,000
4. What can be done about tsunamis to help protect people and property?
> we can install 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 include surface buoys, button pressure recorder, sensors, DART System, tsunami evacuation route, tsunami hazard zone, and evacuation shelter.
