Here's why:
* Deciduous trees: Many trees in temperate climates are deciduous, meaning they lose their leaves seasonally.
* Preparing for winter: As days shorten and temperatures drop in autumn, deciduous trees prepare for winter by shedding their leaves. This helps conserve energy and prevents damage from cold and snow.
* Color change: The leaves often turn vibrant colors (red, orange, yellow) before falling, making autumn a beautiful time of year.
While some leaves may fall in other seasons due to factors like disease, insect damage, or extreme weather, the majority of leaf drop happens in autumn.
