Exploring Earth's Tilt and the Changing Seasons

The video explains how Earth's tilt and orbit around the Sun cause the seasons. It describes how the tilt results in different hemispheres receiving varying amounts of sunlight throughout the year, leading to seasonal changes. A flashlight demonstration illustrates how the angle of sunlight affects temperature. The video also uses a graph to show temperature variations in Toronto, Canada, across different months, reinforcing the concept of seasons.
