• The Earth's orbit around the Sun is elliptical, causing the distance between the Earth and the Sun to change throughout the year.

• The Earth's rotation on its axis causes the length of daylight to vary in different parts of the world.

• The Sun's rays hit the Earth's surface at different angles, depending on the time of year and the location on Earth.
