How do you use shadows to measure?
You can use shadows to measure the heights of trees, or buildings, as long as you can make two separate measurements at exactly the same time of day. While one person or group measures the length of the shadow of the tree or other object, another person or group carefully measures the length of the shadow cast by a smaller object, such as a person, sign, or pole.The ratio of the length of the shadow to the height of the object will be the same for almost every object casting a shadow at that particular moment of the day. So divide the known or measured height of a person by the length of his shadow to find this ratio, then multiply the other shadow length by this amount, to give a good estimate of the height of the taller object.Example:A tree's shadow at 5 PM is found to stretch 80 feet from the base of the tree.A boy is known to be 5 feet tall, his shadow at 5 PM is 10 feet long.(So the shadow length of other objects, measured at 5 PM, will all be twice their height.)5 ft/ 10 ft = 0.5 and 0.5 x 80 = 40 tells us the tree itself is about 40 feet tall.
What is the tree that has no shadow?
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 woman stands next to a tree ans she is 5 feet tall her shadow is 3feet the trees shadow is 7.5 feet long how tall is the tree?
4.5 ft
Who was the swift shadow that Hannah remembered racing into the dark trees the night before?
Hey does anyone know what chapter, and page this was on.
Two trees stand side-by-side The shorter tree is 4 feet tall Its shadow is 9 feet long The taller tree is 18 feet tall How long is its shadow?
Let the shadow be x and use trigonometry and the tangent ratio: 18/x = 4/9 x = 40.5 feet

Why do trees not tend to grow well under trees?
Because of the shadow.

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.
How can you measured controle of the ozone layer depletion?
The ozone is measured in Dobson Units. It can be controlled by planting more trees.
What movement of earth cause the trees shadow to move during the day?
wind
What are the release dates for Shadow in the Trees - 2007?

If a tree is 12 feet tall and has a 16 ft shadow how tall is a tree that casts a 20 ft shadow?
Assuming the shadows are measured at the same time of day and that the trees are on level ground, the tree with a 20-foot shadow is a quarter longer than the tree with a 16-foot shadow. Adding a quarter of the height to 12 feet makes it 15 feet tall. Alternatively use the tangent ratio which will be opposite (height of 1st tree) over adjacent (its shadow) and multiply it by the adjacent of the 2nd tree: (12/16)*20 = 15 feet tall.
Do you measure a tree in meters or kilometers?
Most trees are measured in metres or feet.
Instrument used for measurement the length of trees?
dendrometer

How do trees shade and cool?
They shade and cool by blocking the sun which creates a shadow and makes it shade and cool
