Most surface waves are caused by which factor?

Explanation:
Wind is the main force generating most surface waves. When wind blows across the water, friction transfers energy from the air into the surface, creating waves. The size of these wind waves grows with stronger wind, longer wind duration, and a longer fetch (the distance wind travels over open water). Tides come from gravitational forces and don’t create the bulk of surface waves; currents and seafloor features can alter how waves move and break, but they’re not the primary source of the waves themselves. So the primary cause of most surface waves is wind.
