Fall, also known as autumn, is the season that occurs between summer and winter. It typically spans from September to November in the Northern Hemisphere and from March to May in the Southern Hemisphere. During this time, temperatures begin to cool, and daylight hours shorten as the Earth tilts away from the sun. One of the most notable features of fall is the changing color of leaves on deciduous trees, such as maples and oaks. As chlorophyll breaks down, vibrant hues of red, orange, and yellow emerge. Additionally, many cultures celebrate harvest festivals during this season, highlighting the importance of agriculture and seasonal changes.
