Im taking a test today

if you are on a clockwise spinning object then a projectile fired across it would appear to swerve to the left (visa versa for anticlockwise). This is why tropical storms spin and water spirals down plugholes.

If I stand on the equator I have a eastward velocity of about 1000 miles per hour due to the rotation of the Earth. If I then begin to fly north (or south), I maintain that eastward 1000 mph through conservation of momentum. The ground, however, moves slower as one moves toward a pole because the distance one is from the Earth's axis decreases making for a smaller circle of rotation.
At the tip of Florida, at 25° north, the ground below me is only moving eastward at 935 mph. I now appear to be moving at 65 mph westward relative to the surface of the Earth where I was stationary at the Equator. This is the Coriolis effect. The force that accelerated me from 0 to 65 mph was the Coriolis force.

Imagine a spinning carousel. The whole thing spins at the same rate, but different speeds depending on distance from the center. The edge spins faster than halfway between the center and the edge, for example. If you walk from the edge toward the center, you'lll retain your original momentum as you do, making you go faster than that part of the carousel. You'll tend to fall over. If you walk from the middle to the edge, you'll also retain your original momentum, which is slower than everything at the edge. Again you'll tend to fall over. The same thing occurs with winds blowing to or from the equator. The wind encounters different speeds of the earth's spin, which is about 1,000 mph at the equator but zero at the poles. The wind tends to conserve its original energy, which results in a change of wind direction in order to retain its original speed.

On the rotating earth, the effect tends to deflect moving objects to the right in the Northern Hemisphere and to the left in the Southern Hemisphere and is important in the formation of cyclonic weather systems. The coriolis effect is also an important factor on the movement and direction of major ocean currents.

Throw a ball towards the equator and it lands slightly to one side of where you'd think it would. The Earth moved beneath it while it was in the air.

is it pronounced AUriolis ?? i read / herd some where that it is a dazzling light effect on northern hemisphere ...if am wrong ...let me know what do you mean by coriolis ??
