Autumn foliage refers to the colorful leaves that appear on trees during the fall season. As temperatures drop and daylight decreases, chlorophyll—the pigment responsible for the green color in leaves—breaks down. This process reveals other pigments, such as carotenoids and anthocyanins, which produce vibrant shades of yellow, orange, and red. Different tree species, such as maple, oak, and birch, exhibit unique colors and patterns in their leaves. The intensity and duration of autumn foliage can vary based on factors like climate, soil conditions, and geographic location. This natural phenomenon attracts many people who enjoy viewing the stunning landscapes.
