What forms as a result of the winds frictional force on water?

The correct answer is - waves.

The frictional force of the winds is the force with which the winds influence a surface. The smoother a surface is the lesser the friction, and vice versa. The water is a smooth surface, so the winds frictional force is not very big on it, but it is big enough to cause the occurrence of the waves. By constantly influencing the water with their frictional force the winds manage to move and disrupt the surface of the water, with the end result being the waves. Depending on the strength of the winds and the frictional force accordingly to that the waves can be very small, only few mm in height, or can be up to several meters in height.
