With the weather changing everyday, more and more leaves pile on my grass and in the streets. The wind has a huge effect on this, but I question why some trees still haven't lost as many leaves so far. My cherry tree is average height with many leaves and has only lost a couple that mostly end up on my grass. On the other hand, I have a small and tall tree in my front yard that has lost a lot of its leaves. The remaining leaves on it are already orange and crispy. A few days earlier I took a quick picture of a tree in front of the Lowes at Legends. It didn't look too much affected by the weather. Barely any of the leaves had a change of color. Looking at the three trees it could be because of their contrasting sizes,but I'm not sure.

I did research on why leaves change color and why they eventually fall off. It turns out the that leaves change color and fall off for the same reason. Based on the website
Asheville the leaves on trees are compared to human beings. Just like human beings have their own needs to prepare for the upcoming winter, trees do the same with their leaves. The tree knows that once the frost comes it will kill the leaves, so the tree itself gets rid of the leaves. First, the tree absorbs the "useful nutrients into the twigs" , then the leaves fall. This all depends on the weather. Once the tree feels like the weather is getting too cold it will do this process. Before the leaves fall they are still trying to gain energy. This is the cause of the change of color in leaves. All of this depends on the kind of tree.
This explains why all the trees I have observed all have different characteristics on the leaves they have. Each tree will eventually know when to lose their leaves before the cold and frost.
I really like how I found this out because I thought that trees just lost their leaves as a sign of the leaves dying. But the tree is actually protecting them and itself from the cold. Trees are, for example, like mothers, caring for themselves and their children. In this case the leaves would be the example of children.
