The coriolis effect causes surface ocean currents to flow in straight lines between the poles bend and curve around the planet move more quickly than deep ocean currents sink toward the ocean floor, then rise again to the surface

Bend and curve around the planet.
The Coriolis effect causes the surface ocean currents to bend and curve around the planet. This effect is named after the French mathematician and engineer Gustav Gaspard Coriolis who discovered it. It explains why the winds or the currents in the oceans curve instead of travelling straight. The cause of the phenomenon is the rotation of the earth. It describes why the objects deflect while in motion.
