Seasons and Earth's Tilt in detail
Seasons are caused by the tilt of the Earth's axis, 23.5°, as it orbits the Sun once a year, not by distance from the Sun. When the northern hemisphere is tilted toward the Sun, it has summer, with longer days and more direct sunlight, and the southern hemisphere has winter.
At the equinoxes (around 21 March and 23 September), day and night are equal everywhere, and at the solstices (21 June and 21 December) the Sun is overhead at the Tropic of Cancer or Capricorn, giving the longest or shortest days. Seasons affect climate, farming and daily life, especially away from the tropics.
