Off Kilter

Dr. Forrester explains Earth's axis tilt and its impact on seasons. The tilt, possibly caused by a large impact billions of years ago, results in the four seasons: summer, fall, winter, and spring. Each season has distinct weather patterns affecting flora and fauna. The Earth's tilt towards or away from the sun influences sunlight angles, creating longer or shorter days. Equinoxes occur when day and night are equal, while solstices mark the longest and shortest days. The video concludes with the idea that Earth's tilt is crucial for seasonal changes.
