What are long shadows?

Long shadows are big, stretched-out shapes that appear on the ground when something blocks the light from a source like the sun or a lamp.

Imagine you're playing with your favorite toy in the afternoon. The sunlight is coming from one side, and your toy casts a shadow on the floor. Now picture it’s almost evening, the sun is low in the sky. That same toy now has a long shadow that stretches out far across the room! It looks like the toy is reaching for something or trying to run somewhere.

When the light source is close, like a lamp on your table, the shadows are short, just a little behind your toy. But when the light comes from high up and far away, like the sun in the sky, the shadow gets stretched out, making it look longer and thinner.

Think of a tree near your house. In the morning, its shadow is short and close to the tree. But by afternoon, the same tree casts a long, wiggly shadow that might even reach your driveway, just like a big, sleepy dragon stretching out on the ground!
