Why do seasons shift and reverse across the globe?
In short: This video explores the mechanics behind seasonal changes, examining how Earth's axial tilt and orbital shape dictate temperature variations and why the hemispheres experience opposite seasons.
The video examines how the Earth's tilt on its axis and the specific shape of its orbit around the Sun determine the intensity of sunlight reaching different regions. These factors explain why some areas endure constant heat while others face freezing temperatures and snow. Furthermore, it clarifies why the seasons are reversed between the northern and southern hemispheres.
