Step 1: Understanding the Concept:
The Coriolis Effect is an apparent deflection of moving objects (like wind and ocean currents) when viewed from a rotating reference frame, such as the Earth.
Step 2: Detailed Explanation:
Because the Earth rotates on its axis from west to east, different latitudes travel at different linear speeds. The equator spins much faster than regions near the poles.
As air or water moves freely across the globe, the ground beneath it rotates.
This rotation causes freely moving fluids to deflect to the right of their path in the Northern Hemisphere and to the left in the Southern Hemisphere.
Earth's revolution around the sun causes seasons.
The Moon's gravity primarily causes ocean tides.
Uneven heating of the Earth creates pressure gradients, which initiate the wind, but it does not cause the deflection (Coriolis).
Step 3: Final Answer:
The primary cause of the Coriolis Effect is the Earth's rotation on its axis.
