Ekman spiral continued....
The deeper water does not feel the wind, but it does feel the water above moving. So the same thing happens again, except this time the water goes in a direction even further from that of the wind, and so on, turning as we go deeper. At each step, we lose a bit of force, so we have less and less as we go down.

When there is wind over water, the water's direction is normal to that of the wind. Whether it goes left or right is decided by the side of the mother ball we are on. Since the mother ball turns, the water closest to the middle goes the fastest. So when wind carries water further away from the middle, the water keeps its force, and that's why it doesn't move in the same direction as the wind. Continued....
