A shadow is made when an object blocks out light coming from a light source. because there is less light particles in that area, surfaces don't reflect as much, making it darker in that area. that is why you can't see when there is no light source.
when a shadow is formed there should be an opaque object the picture can be formed on the screen.
shadow
A normal shadow.
By projecting imaginary lines from the light source to the object, you can explain this geometrically. The closer the light source, the wider the angle formed between the lines, and the wider the angle, the longer the line opposite will be.
because the tree is blocking the light source so it forms a shadow.

at noon the shadow is point sized {smaller} and in morning and evening the shadow is the longest.
The shadow formed would be tetrahedrons with an nostalgic way of cooperating with the society at that time.
