Earth’s seasons are not caused by how close we are to the Sun, but by the planet’s axial tilt. In this episode, we explore how Earth’s 23.5-degree tilt affects the angle and intensity of sunlight received across different regions throughout the year, creating the cycle of spring, summer, autumn, and winter.
You’ll learn how the tilt influences day length, solar energy distribution, and temperature changes, and why the Northern and Southern Hemispheres experience opposite seasons at the same time. We also clarify common misconceptions—such as why Earth is actually closest to the Sun during Northern Hemisphere winter—and examine how seasons differ near the equator and the poles.
This episode offers a clear, science-based explanation of one of Earth’s most familiar yet often misunderstood natural phenomena.
