Also I have been talking about this day here on the weather blog all month long and it is now HERE! Yes, it is the first day of Autumn! The air is fresh the trees are starting to change colors and I'M loving every minute of it. Oak so maybe I should calm down a little :-) So because it is the first day of Autumn I thought we would have a few quick Fun Facts about Autumn here on JIWB.~ What are leaves for?
A leaf is like a miniature factory. It takes the ingredients of sunlight, water, carbon dioxide, and chlorophyll to make food for itself.
~ Why do leaves fall off trees in the autumn?
In autumn, there is less sunlight because the days are shorter. Because sunlight is a crucial ingredient in the leaf "factory", the leaf is unable to sustain itself any longer. It becomes weak, breaks from the branch, and floats to the ground.
~ Why are leaves different colors in autumn than the rest of the year?
I'll bet you didn't know that leaves are really red, yellow, orange, and brown all year long; we just can't see it! The intense green pigment of chlorophyll actually blocks the pigments of the other colors. You could say that the other colors are "invisible". In the autumn, red, yellow, orange, and brown become visible and bright when the green chlorophyll weakens before the leaf falls off the tree.
To make things more fun here is a link you all can check out. http://www.quizmoz.com/quizzes/Trivia-Quizzes/a/Autumn-Trivia-Quiz.asp
