• A season is a period of the year distinguished by special climate conditions. The most familiar seasons are winter, spring, summer, and fall. However, many cultures also have a monsoon season, and still others only recognize rainy seasons and dry seasons.

    Seasons occur because Earth is tilted on its axis as it rotates around the sun. Earth's axis is an invisible line that runs through its center from pole to pole. Places near the Equator experience little seasonal variation. They have about the same amount of daylight and darkness throughout the year. The angle of the sunlight also does not change much, so these places remain warm year-round.
