Winds and gravity start water moving across the globe, but the currents that form do not flow parallel to the wind or in a straight line. Instead, the currents move at an angle or curve as they move in easterly or westerly directions. What causes this curving pattern?
A) the Coriolis effect
B) changes in water density
C) Earth's tilt on its axis
D) unequal heating between the equator and the poles
