Earth's spin bends the path of anything that flies or flows far enough
A cannonball, a hurricane or an ocean current moving over a long distance drifts sideways from where it was aimed, because the ground underneath is also rotating, just at a different speed. Gaspard-Gustave de Coriolis worked out the mathematics in 1835 while studying waterwheels, not weather. It's why hurricanes rotate counterclockwise north of the equator and clockwise south of it.
