Countries in temperate zones of the southern and northern hemispheres have four seasons. They are Spring, summer-fall, and cold winter but these are not that significant in countries that are near the equator!
The weather changes in the fall, making the air turn cold. During this time, many leaves also change colors. Why does this happen?
First, let's think about why some trees drop their leaves before winter. In the winter, it would take a lot of energy and water for plants to keep their leaves healthy. But winter is cold, dry, and usually, there isn't much sun (which helps give plants energy). So, instead of trying to keep their leaves, some plants drop their leaves and seal the spots on their branches where the leaves had been attached.
How is this related to what makes leaves colorful?
Chlorophyll is an important pigment for plants to make food using sunlight.
This is called Photosynthesis
During spring and summer when there is plenty of sunlight, plants make a lot of chlorophyll.
When it starts to get cold, some plants stop making chlorophyll. Instead, those plants break down chlorophyll into smaller molecules. As chlorophyll goes away, other pigments start to show their colors. This is why leaves turn yellow or red in fall.
