The ocean stays blue because the water reflects and absorbs light. When sunlight hits the ocean, the blue light bounces around in the water and comes back to our eyes. The other colors get absorbed deeper down, so we only see blue from above. Imagine a big pool of blue paint, no matter how you look at it, it’s still blue.
Examples
- A clear swimming pool always looks blue, even if you’re standing by the edge.
- The sky is blue when it’s sunny, and the ocean is blue when you look at it from a boat.
- Even on cloudy days, the water still seems to be blue because of how light moves through it.
