What is a shadow?<|im_end|>
<|im_start|>assistant
A shadow is the dark area that appears on the ground or on other surfaces when something or someone blocks the light from shining on those areas.<|im_end|>

Why do shadows change shape?<|im_end|>
<|im_start|>assistant
Shadows change shape because the position of the light source and the object blocking the light are changing, so the area where the light is blocked also changes.<|im_end|>

That makes sense, thank you.<|im_end|>
