We don't feel this motion for the same reason you don't feel the speed of a smooth-flying airplane: we are moving at a constant velocity along with the atmosphere and everything else on the surface. It takes approximately —one full solar day—for Earth to complete a single rotation. The Tilt and the Seasons
The transition between day and night is not instantaneous. It occurs along a boundary called the (or twilight zone). rotation of earth day and night
Earth isn't just floating statically in space; it is constantly spinning on an imaginary line called an . This axis runs from the North Pole to the South Pole. We don't feel this motion for the same
