Wind provides the energy to set waves in motion. This energy principle works the same way waves are created if you snap one end of a rope in the floor. An energy shockwave will create several waves until the other end.
The size of the wave is determined by:
-The speed of the wind
-The distance of the wind blowing over the water
-The lenght of time the wind is blowing
The top of the wave is the "crest", the bottom is the "trough", the difference between crest and trough is the "height". The distance from one crest to another is the "wave-lenght".
Once a wave height reaches a seventh of the wave-lenght it falls down making white caps.
Just for general knowledge: "Tsunamis" (huge waves) are not created by wind, but by underwater earthquakes |  Report
