Why do seasons change throughout the year on Earth?
The tilt of the Earth's axis
The Earth's axis is tilted at about 23.5° to the perpendicular of its orbital plane, and this tilt stays in the same direction as the Earth revolves around the Sun.
Because of this, each hemisphere is tilted towards the Sun for part of the year (longer days, more direct rays – summer) and away for the other part (shorter days, slanting rays – winter).
The Moon's pull causes tides, the Earth–Sun distance changes only slightly (the Earth is actually nearest the Sun in January), and rotation causes day and night, not seasons.
Hence, The tilt of the Earth's axis.
