What causes the seasons?
? 2014 Pearson Education, Inc.
Axis tilt changes directness of sunlight during the year.

Sun's altitude also changes with seasons
Sun's position at noon in summer: Higher altitude means more direct sunlight.
Sun's position at noon in winter: Lower altitude means less direct sunlight.
Summary: The Real Reason for Seasons
? Earth's axis points in the same direction (to Polaris) all year round, so its orientation relative to the Sun changes as Earth orbits the Sun.
? Summer occurs in your hemisphere when sunlight hits it more directly; winter occurs when the sunlight is less direct.
? AXIS TILT is the key to the seasons; without it, we would not have seasons on Earth.
