Depending on where you are, the ocean/sea/pond/pool of water can be a beautiful clear blue.
While in some instances, it is green in colour.
This simple question came up in a middle while out with friends in the zoo today. I vaguely remembered this being covered in primary/secondary school science, but thought it was a good time for a refresher.
Why is the ocean blue in some places and green in some other?
Hint: wavelengths.
The ocean is blue because water absorbs the wavelengths of other colours and reflect only blue wavelengths into our eyes.
The ocean is green in some places due to the presence of algae and plant life, which reflect green wavelengths into our eyes.
Just a small refresher tidbit from middle school if you have forgotten!

Or the ocean is blue as it reflects the colour of the blue sky.
ReplyDeletewavelengths? so green oceans have smaller waves than blue oceans?? seriously...
