Coriolis Effect Activity How does Earth’s rotation affect wind?   If the earth was not spinning, the wind would always blow straight from the south in the Southern Hemisphere, and from the north in the Northern Hemisphere pushing the surface ocean currents straight as well. However, the earth DOES spin (rotate). This turning of the earth has a very important effect […]
