Why are shadows cast on the ground?
A shadow is a place where direct light has been blocked from reaching in the presence of direct light around it. Because most direct light is received from the sun, the shadow is cast on the ground. The light would normally have reached the ground, but something (a person, a building, a cloud, etc.) blocked the light between the sun and the ground resulting in a shadow.
Why the shadow of flying bird is not seen on the ground even though it is opaque?
If you see a bird but do not see a shadow on the ground, it is probably because of the angle the light is coming from. If you drew an imaginary line form the source of light, (probably the sun) through the bird, you would find the shadow of the bird where the line touched the ground. If there is no light, the bird cannot make a shadow.
Where does the light come from that causes the shadow of the umbra and penumbra?

as there is no sunlight at 8pm,and shadow is formed when light can not pass through that object casting shadow and if u throw light on tree it will not cast shadow on the ground as it only can happen before sunset.....
How according to the position of light source does the size of shadow differ?
It's hard to explain this in words but here goes.There are two ways a shadow changes size based on the position of the light source.If the light is just above and in front of the object the shadow is long, but as the light moves above the object the shadow gets shorter and shorter and shorter until when the light is directly above the object there is little to no shadow at all.If the light is directly in front of an object, like a person, as the light gets closer the light rays can only get past the object at a wider and wider angle (out to the sides) so the area with no light (the shadow) becomes wider and wider.
What causes a shadow to change shapes?
the object blocking the light or the light source are moved or changed. A shadow is created when an object is placed in the path of light. If the object remains unchanged then the movement of the light that is casting the shadow will alter the shape.
Why is your shadow sometimes in front of you and sometimes. behind you?
Your shadow will fall in the direction opposite the source of light - with you between the light source and the shadow. The direction of your shadow relative to you will depend on what direction you are facing.If you are facing toward the light source, the shadow will be behind you.If you are facing away from the light source, it will be in front of you.If you have the light source to your right, the shadow will be to your left.If you have the light source to your left, the shadow will be to your right.If the light source is directly above you, the shadow will be directly under you.If you move past a light source, your shadow will move from behind you to beside you and then to in front of you.
Why do we have shadow?
Shadows are caused when an object is blocking the light causing the shape to appear on the ground in the opposite direction of the source of the light. A shadow only appears in the light or when any shining object faces them. All objects in the way of the light will appear with a shadow in the opposite direction of the source of the light.
How does the length of a shadow get longer?
The light source moves strait above the object
Why can't you step on your shadow's head?
