TED-Ed: Reasons for the seasons - Rebecca Kaplan

The video explores the concept of seasons, challenging common perceptions by explaining that distinct seasons occur only in specific regions. It delves into Johannes Kepler's discovery of elliptical planetary orbits and clarifies that Earth's orbit is nearly circular. The video highlights that Earth's axial tilt, not its distance from the sun, is the primary reason for seasonal changes. It explains how axial tilt affects daylight hours and solar energy distribution, influencing temperature variations across different regions.
