Answer 2

The following three things are required for a shadow to form: a source of light,An opaque object, a screen.

Shadows are formed because light rays travels in a straight line, and they cannot bend round the corners of the objects. The shape of the shadow is also the same as the shape of the object because light travels in a straight line path. When a bird is on the ground, we can see its shadow which is formed by sunlight.
