season
Sign in to saveA season is a division of the year based on changes in weather, ecology, and the number of daylight hours in a given region. On Earth, seasons are the result of the axial parallelism of Earth's tilted orbit around the Sun. In temperate and polar regions, the seasons are marked by changes in the intensity of sunlight that reaches the Earth's surface, variations of which may cause animals to undergo hibernation or to migrate, and plants to be dormant. Various cultures define the number and nature of seasons based on regional variations, and as such there are a number of both modern and historica
AI overview
A season is a period of the year defined by distinctive weather patterns, changes in plant and animal life, and varying amounts of daylight, caused by Earth's tilted orbit around the Sun. Seasons matter because they trigger important natural cycles—like animal migration and hibernation, plant dormancy—and different cultures recognize seasons differently based on their local environment.
