What causes the Coriolis effect?

The Coriolis effect happens because Earth spins as we move around it, like a giant spinning merry-go-round.

Think of Earth as a big, spinning ride. When you’re on a merry-go-round and you walk from the center to the edge, you feel like you're being pushed sideways, that's because the ride is spinning underneath you. Similarly, when something moves across Earth’s surface (like wind or ocean currents), it gets pushed sideways too, just like you on the ride.

Earth spins from west to east. If you’re in the Northern Hemisphere and moving forward, say, a bird flying from one place to another, it will seem like it's being pushed to your right. In the Southern Hemisphere, it gets pushed to your left. This sideways push is what we call the Coriolis effect.

So instead of going straight, things curve, just like when you run on a spinning ride and feel that fun little nudge! The Coriolis effect happens because Earth spins as we move around it, like a giant spinning merry-go-round.
