The "fetch"http://en.wikipedia.org/wiki/Fetch_%28geography%29
the wind!
The size of waves is primarily influenced by the wind speed and the distance (fetch) over which the wind has blown. Stronger winds and longer fetches tend to create larger waves.
ocean waves
It is the winds, often far out into the oceans, that create waves.
Winds blowing over a large area create powerful, high, and fast waves.
Wave size is determined by the energy and distance the wind travels over the water's surface. Factors such as wind speed, duration, and fetch (the distance the wind travels across the water) influence wave size. Stronger winds blowing over longer distances will create larger waves.
Big waves are typically created by strong winds blowing over a large distance of open water, called fetch. The longer the fetch and the stronger the winds, the bigger the waves. Other factors such as storms, tides, and underwater topography can also contribute to the formation of big waves.
The winds from a hurricane blowing across the water's surface creates waves. The stronger the wind, the bigger the waves. Put some water in a bowl and blow across the surface. You made waves.
Earthquake or Strong Winds
no, it is actually the other way around
Strong winds can create waves larger than normal.
Waves are created by the transfer of energy from winds blowing across the surface of the water. The friction between the wind and the surface of the water causes ripples to form, which can develop into waves as they travel across the ocean.
