In waves nutrients are circulated and reused. Waves are formed by energy in wind. The energy in wind transforms itself into energy in the water, to form a wave. There are three factors into creating a wave, they are how fast the wind is blowing, how long the wind is blowing and the distance of the water in which the wind has been blowing over. The more these factors take place, the bigger the wave will become. The rougher the water is, the easier the wind can transfer itself. If you are on a calm a sea, he wind has practically no controll on the water. When ripples form in the water allowing the the wind a better grip. Depending on the wave, the movement is different. Bigger waves are found in areas of the earth were the wind consistenly blow in a constant direction. With waves having so many molecules, the height of the waves are unlimitted. Some waves only move up and down, and some can only more horozontally. There are three types of waves that are created when stress is released in earthquakes. There are primary waves (P waves), secondary waves (s waves), and surface waves. Primary waves are the fastest waves that are first detected by seismographs, they are fast, do to there ability to move through both liquid and rock. Suface waves are waves appearing after primary waves. These waves are ably to cut through rock as they travel in a sideways direction, at right angles. These waves are more hazardous waves due to their size, they are bigger than primary waves. The last, or slowest waves are surface waves, and they move cloesly to the surface of the ground. There are two types of suface waves, love, waves, which move like secondary waves, but only horozontally, and rayleigh waves, which move horozontally, and vertically. There are four differnet parts to a wave. There is the crest, which is the highest part of a wave. There is the trough, which is the slowest, and smallest part of the wave. The wavelenghth is the distance of two of the same parts of a wave, such as crest to crest, or trough to trough. Then there is the amplitude of a wave, which is the height of the wave. There are many different waves, the most common of them all, is a tsunami wave. A tsunami wave is a series of waves. A tsunami is caused by an underwater earthquake with the Ritcher Scale. Tsunami's travel at great speeds, an avergae tsunami travels about 600 mph. Are advances in technology allow us to now be able to detect a tsunami wave, there for saving many lives. Tsunami's are very rare, but when they strike they are devistating. Approximaltey six tsunami's hit the coast every century, many accuring in the Pacific.  Waves are a unique part of our world. They are fun, but at the same time has its risks. Waves are important to learn about for going into open water. You must know what a safe is and what isn’t, to make our oceans a safer place. WAVES:
