Why does a shadow form behind an opaque object?
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.

How does the surface behind a shadow affect the shape and size of an shadow?
If the shadow is on a convex surface, it will be bigger. On a concave surface it will be smaller. If the light source is at a low angle to the opaque object causing the shadow (e.g. you're casting a shadow from a flashlight behind you, to a sidewalk in front), the shadow will be relatively tall. If the angle of the light is high (e.g. sun nearly overhead), the shadow will be short. This will also depend on the angle of the shaded surface.
At what time is the shadow in front of you?
The shadow is in front of you when the sun is behind you, typically in the late morning or early afternoon. The length and direction of the shadow will vary depending on the position of the sun in the sky.
What five letter word is the name given to the shadow of Earth on the Moon?
There are two main shadows that Earth projects; one is called the 'umbra', which is the complete shadow where all direct light is blocked out, the other is the 'penumbra', which is a partial shadow. The effect is similar to standing in front of a light source and seeing both a dark shadow in the middle (the umbra) and a lighter shadow on the outer edge (the penumbra). During this eclipse the Moon will pass through both shadows.
