The position of the sun through out the day?
The Earth's rotation changes the angle of the sun as the day passes, so the shadows change based on the position of the sun in the sky. If the sun is up high (around noon), the shadows will be short or not appear to exist (they are under or nearly under the objects). As it gets later in the day, the shadows get longer.
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.
The lower the sun is behind you, the longer your shadow will stretch before you.
Yes it does change, eventually the further away you go the lighter the shadow gets. And depending on if you move a couple of centimetres off, the shadow might start to contour!
Use polarized light.
The length of an object's shadow is determined by ... -- the length of the object, -- the angle between the object's length and the surface on which its shadow appears, -- the distance between the object and the surface on which its shadow appears, -- the angular size of the light source as seen from the object, -- the angle between the direction to the light source and the normal to the object.
when you change the object that creates the shadow by blocking the light, its' shadow will change. or there is another light source shining from a different direction on the object will affect the shadow too.
the position of the sun
when you move and when the sun angle changes
The shadow is caused by the earth blocking the path of the light from the sun casting shadow on the moon. When the earth is not in between the sun and the moon then we have a "full moon."
it is not a shadow
It is simply the shadow of the earth over the moon. When none of the earth's shadow covers the moon, it is a full moon.
Shadows change when the sun moves in the sky because it hits objects from different directions, which causes them to cast a different shadow.
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.
the shape of the moon is caused by the movement of the earth. Earth's shadow causes the shapes. As the earth moves, so does its shadow, creating different shapes (phases).
lunar eclipse
The sun and the earth cast a shadow over the moon while they revolve so the shadow will decrease and increase over the moon by which part of the moon is visible by the sun.
