if you are under a big tree then the tree covers the sun and you get cooler becuase the sun makes you hotter
because the tree is blocking the light source so it forms a shadow.
The leaves give out water which vapourises absorbing some heat as latent heat
The (strong) tendency of light to travel in a straight line.
The tree (and any other solid object) blocks the path of the sunlight, because sunlight can not pass through, or go around an object(unless the object is trnsparent.
The air just close to the surface of hot earth will be less dense where as the air well above will be comparatively cooler and more dense. As light from a tree top travels towards the surface has to go right from denser to rarer and so total internal reflection takes place and reaches the observer as if the image of the tree top is seen on the surface of the earth. This is mirage.

A shadow
the answer is 25.
The kind of climate that is necessary to grow a lime tree is moderate to sunny climates though there are a few varieties such as the persian lime tree that can withstand a cooler climate.
You feel cool under a tree because it blocks out the sunlight (the heat and the light) so the area in the shade becomes cooler.
Well, no trees have a shadow if it is dark, or if they are shaded by a bigger tree. But a family tree may have no shadow.
A tree's shadow does not have light. Anytime you are in the shadow of another object your body has no shadow of its own.
The tree is 12.5 feet in height
because the tree is blocking the light source so it forms a shadow.
Light from the sun (or any other source) travels in particles, which strike objects and are often partially absorbed. A shadow forms behind a tree because when the particles hit the tree, they are absorbed and reflected, so that everything on the other side of the tree, where the light would have gone, receives no light. However, some light will bounce off of other objects and go behind the tree in the other particles' place. Since this other light will already have been partially absorbed, it will be more dim than direct light. Because of this, we are able to see in the shadow, but since the light there is not as strong, it is darker. This darker region behind the tree, is the shadow.
We can not tell because we do not know how straight the tree is or if the ground is perpendicular or level.
The man is twice as high as his shadow. Therefore, the tree must also be twice as high as its shadow, which would make the tree 40 feet tall.
