Why is water blue?
Wait. I know the answer. Ehh I'll just see wat u other ppl think it is >_<
Water is clear, but algae colours it.
It's not... waters clear.
2 me i tink its blue cause .................hmmmm i really dont no but good question doh
it's blue because the sky is blue. the water is actually clear but the reflection of the sky on the water makes it look blue. so during a cloudy day the sky is gray and so is the sea
Well, it has something to do with the spectrum, it is naturally blue IIRC. but light, particles, surrounding color(think pools,etc), depth, etc take into account as well. http://whyiswaterblue.com/
