Question 1056Navigation General

70% to pass

The velocity of the wind, its steady direction, and the amount of time it has blown determines a wind driven current's _______________.

A density
B temperature
C deflection
D speed
AI Explanation

The correct answer is D) speed. The velocity of the wind, its steady direction, and the amount of time it has blown determine the speed of a wind-driven current. Wind blowing steadily over a body of water will create a surface current that moves in the direction of the wind. The speed of this wind-driven current is directly related to the wind speed, direction, and duration. The other options are incorrect because they do not directly determine the speed of the wind-driven current. Density and temperature are properties of the water, not the current itself, and deflection refers to the Coriolis effect, which influences the direction of the current rather than its speed.
