Essential Questions:
What are sea waves?
The waves or sea waves are deformations of the ocean surface.
There are diferent types of sea waves?
There are three types of sea waves, these are wind waves, tsunamis and Tides.

Why they are formed?
Wind Waves are formed by wind (air pressure), these waves are the most frequent and communes, usually these are short waves (100 m). Tsunamis are formed by earthquakes, landslides or volcanic eruptions, in most cases when a strong earthquake occurs somewhere that has sea near, it is probvable that a tsunami is formed. These waves are long waves. (100 Km). Tides are formed by the astronomical forcing; these are always long waves. (10,000 Km)
Key Terms:
Wavelength is the distance that a wave travels at a given time. This time is the time between two consecutive maxima of some physical property of the wave. In the case of the sea waves, these may be the position of the molecules relative to sea level. When there is a disturbance, is advanced at a given speed. If we measure what moves in a given time taken by one of its molecules to pass two consecutive times, we obtain the wavelength (waves). In this case, the distance is the distance between two consecutive peaks. The speed of propagation of the tsunami depends on the depth of the ocean and can be calculated according to her. Thus, if the depth of water decreases, speed decreases tsunami. Approaching shallow waters, waves and refraction phenomena suffer decrease its velocity and wavelength, increasing its height.

Unit Overview And Interesting Facts
- In deep seas these waves may go unnoticed because you only have amplitudes bordering the meter; yet to reach the coast may exceptionally reach up to 20 meters high.
- When the depths are very large tsunami wave can reach high speed.
- Tsunamis typically have wavelengths in excess of 50 kilometers and can reach up to 1000 kilometers.
- A wave generated by wind and only in major storms can reach 300 meters wavelength.
- The tallest wave ever measured was 1719 feet at Lituya Bay, Alaska.
- The tallest wave recorded in the open ocean was 95 feet during a storm near Scotland.
- The moon and the sun cause the most gravitational pull in waves.
