Uses of the Sun

Uses of the Sun. The Seasons on Earth. The combined effect of the Earth's annual motion around the Sun and the tilt of its axis cause the seasons. The length of time the Sun is above the horizon (daylight) changes. The path the Sun follows across the sky varies; the Sun's declination changes.
