Thatâs because the Earth tilts in relation to the sun. That is what creates the differences in the seasons and the annual warming and cooling cycles of the Earthâs Northern and Southern Hemispheres. The Earth is tilted 23.5 degrees on its axis, a straight line through the planet from the North Pole to the South Pole. The Earth spins around, or rotates, on this axis as it orbits the sun. The key here is that as the Earth orbits the sun, different regions on Earth tilt both towards and away from the sun, depending on the regionâs respective hemisphere.
