We canât feel Earthâs rotation or spin because weâre all moving with it, at the same constant speed. Earth spins on its axis once in every 24-hour day. At Earthâs equator, the speed of Earthâs spin is about 1,000 miles per hour (1,600 kph). The day-night has carried you around in a grand circle under the stars every day of your life, and yet you donât feel Earth spinning. Why not?
The earth rotates in about 24 hours, so the surface of the earth at the equator is moving due to earth rotation at about 900 nautical miles / hour (knots) so about 1,035.7 mph. If the atmosphere didn't rotate with the earth then the earths surface would be moving past the atmosphere at the equator at 1,035 mph. The effect of the atmosphere travelling across the earths surface is that thing we know so well called wind.
