Why is it cooler near trees?

Question

So I am sure a lot of you have noticed that when you are in a grove or forest it is cooler than an area that has less dense vegitation. My husband and I have had this conversation for days- but we want the real scientific answer. I can't seem to find it through research- so some one just tell me already!

Answer 1

It is because of 2 reasons ;

1. Trees give shade and cut off sunlight and reduce the heating of air and soil below the,.

2. Trees transpire and give out water in the atmosphere which again reduces the temperature.

Answer 2

co2 is cooler than o2 and they give ya shade the sun light needed to heat ya up is blocked

Answer 3

Tree evaporate an enormous amount of water.  They are constantly pulling up water from their roots and expiring it through their leaves (mostly on the undersides).  

That how they transport nutrients from the soil to the rest of the plant.  It's sort of like their blood for animals.

When water evaporates from a liquid to a gas state it absorbs energy through evaporation.  (Like if you leave a wet towel out to dry it will feel cooler than the air.)  So the trees are like giant evaporative (or swamp) coolers.

Plus, they provide shade.   But mostly it's them acting like giant evaporative coolers (Sorry nothing to do with oxygen.)

Answer 4

I cant say it scientifically but I guess its because trees actully convert(if thats the right word) Carbon dioxide into oxygen so when your near them it can be cooler.
