A season is one of four periods in a year defined by changes in temperature, weather, and daylight hours. Seasons are caused by the earth's position relative to the sun, changing as the earth moves closer or farther from the sun. However, places near the equator do not experience seasons because their position does not change relative to the sun. The four seasons are autumn, winter, spring, and summer, each with characteristic weather patterns and events.
