In summer, flowers and trees are in full bloom. The leaves on trees are green.
Autumn is the fourth season of a new year.
Autumn is also called “fall” because the leaves change colors and fall off the trees.
Autumn weather can be chilly or cold, windy, and rainy.
Why do the seasons change?
The seasons change because
of the tilt of earth’s axis.
Why Are Leaves Green in Spring and Summer? Plants make their own food using sunlight and something called chlorophyll. Chlorophyll gives leaves their green color.
Why Do Leaves Change Color In The Fall? Many plants stop making food in the fall. The chlorophyll goes away. Then we can see orange and yellow colors. These colors were in the leaves all summer, but the green covered them up. Some leaves turn red. This color is made in the fall, from food trapped in the leaves. Brown colors are also made in the fall. They come from wastes left in the leaves.
