What Causes ‘Seasons’ and Why Do They Change?

Seasons happen because Earth moves around the sun, and its tilt changes how much sunlight we get. Imagine Earth is like a spinning top, it tilts as it goes around the sun. When one side of Earth leans toward the sun, that part gets more warmth and light, making summer. The other side leans away, getting less sunlight, which makes winter.

Examples

  1. Imagine Earth as a spinning top that leans one way when it's summer in your hemisphere and the other way when it's winter.
  2. If you live near the equator, seasons are less noticeable because both hemispheres get similar amounts of sunlight throughout the year.
  3. When it's springtime for you, it's autumn for someone on the opposite side of Earth.
