The rhythm of the Northern Hemisphere is dictated by a dramatic cycle of four distinct seasons: Spring, Summer, Autumn (Fall), and Winter. Unlike the more stable tropical belts, the Northern Hemisphere experiences extreme swings in temperature, daylight, and weather due to the tilt of Earth’s axis (approximately 23.5 degrees) relative to its orbit around the sun.
