As Earth journeys through its 365-day orbit, different parts of the planet receive varying amounts of direct sunlight.
The transition between these seasons relies entirely on astronomical mechanics. Understanding the four seasons requires looking at the science behind Earth's movement, the unique characteristics of each season, and how geography dictates how they are experienced worldwide. The Science Behind Seasonal Shifts what are the four seasons
Earth rotates on an axis that is tilted at an angle of 23.5 degrees relative to its orbital plane. This tilt remains fixed in space as Earth circles the Sun. As Earth journeys through its 365-day orbit, different
