Why Do Oceans Sometimes Look Like Mirrors?

Imagine the ocean is a big puddle. When it's calm, it looks like glass because there are no waves to make ripples. Light bounces off the surface just like how light bounces off a mirror, that's why it looks so still and shiny!

How It Works

When the wind is gentle or not moving at all, the water doesn't move much. This makes the ocean look smooth and calm, creating a perfect reflection of the sky.
