The change of seasons is mainly the result of the tilt of Earth's invisible spin axis, which is inclined 23.5 degrees in comparison to the axis of the Sun. Sometimes Earth's axis is tilted toward the Sun and sometimes away from it -- and somewhere in between for the rest of the year. It is this tilt combined with the motion of the Earth around the Sun that causes more or less light to fall on one hemisphere or the other during each of the seasons. This means that the amount of sunlight falling directly on a parcel of Earth changes throughout the year. It also means that days get longer or shorter, causing the Sun to warm part of the Earth for longer and shorter periods of each day.
