LEAVES!!!!

Today i am going to tell you how leaves change color in this time of year and why the sunlight is less in the fall. I am also going to talk about how the seasons change.

Leaves change colors because this time of year has less sunlight so trees shut down and can not produce anymore chlorophyll then it fades away.In the summer or spring chlorophyll completely covers the leaves so really they have colors underneath them instead of green.  
   Chlorophyll
In this time of year there is less sunlight because the Earth is tilted more away from the sun. This process is the same as when the seasons change because the Earths is tilted on its axis.
