Winter occurs when a hemisphere is tilted away from the sun. It is characterized by cold temperatures, frost, and, in many regions, snow.

In tropical regions near the equator, the four-season model often shifts to two: the and the dry season , driven by rainfall patterns rather than temperature shifts. Why the Seasons Matter Winter occurs when a hemisphere is tilted away from the sun
The equinoxes and solstices mark the turning points of this cycle. In tropical regions near the equator, the four-season
The four seasons—spring, summer, autumn (fall), and winter—are a fundamental rhythm of life on Earth for most of its inhabited surface. Far from being a simple calendar division, each season is a distinct chapter defined by predictable changes in weather, daylight, and ecological behavior. This cycle is not caused by Earth’s distance from the Sun, but by a more elegant celestial mechanism: the planet’s axial tilt.
Summer is the hottest season of the year. It occurs when that hemisphere is tilted most directly toward the Sun.
