It reflects the sky. : D

I nicked this answers from some site.

1) You have probably noticed that the sea is not very blue-looking when the sky is overcast. Water reflects and scatters the light that strikes it; this is shown by the fact that you can see your reflection in puddles. When the sky is brilliant blue, the sea is also, because it reflects the blue of the sky.

2) Blue light is more easily bent, or refracted, than red light; thus, light refracted back from the surface of the sea appears blue. Furthermore, when you are underwater the water around you appears blue because more blue light is scattered back to your eye than red light.

actually, the blue sea happens not as simple as u guys thought... "reflecting the blue sky".... lol....
i've heard the same question before... but at the time, my teacher answer it in more scietifically answer....
i kinda remember what he said... but too confusing if i have to explain it in here..... just browse yahoo or goodle... hopefully u will get the answer there... but then again, it's not something that really important.... just enjoy the beauty of the sea.... any more question about it, will only make another confusion for u....

I think because when it's sunny the sky is blue so it reflects to the water. When it's raining and dark, the water is grayish right.?

isn't it because of the sun rays reflecting of of the ocean and water molecules/vapor??? (never was good in science....... )

but overall this is a very pointless thread......

A. The sea reflects the sky.
You have probably noticed that the sea is not very blue-looking when the sky is overcast. Water reflects and scatters the light that strikes it; this is shown by the fact that you can see your reflection in puddles. When the sky is brilliant blue, the sea is also, because it reflects the blue of the sky. A good answer to why the sky is blue has already been posted at MADSci.

B. The sea refracts light just as the sky does.
Blue light is more easily bent, or refracted, than red light; thus, light refracted back from the surface of the sea appears blue. Furthermore, when you are underwater the water around you appears blue because more blue light is scattered back to your eye than red light. Here are some professional shots to show what I mean.
The scattering of light by the air, or by water, is called Rayleigh scattering.

sorry if this sounds offensive, but it's really dumb to think the ocean is blue O.o. the ocean ain't blue. it's collourless, it's see through. it looks blue cuz of the reflection of the sky. that's why it's black at night and gray when it's clouded.


It's not really dumb IMO to think the ocean is blue. Cause when the sky is reflected on it, it IS blue.

Every colour you see is reflected, so saying the ocean is not blue just cause the colour's from the sky, kinda ironic.

One answer.

food coloring.

why one answer you ask?

food coloring would in turn color the water blue and route all the scientific ideas.

and then on the other hand, if one is stupid they would take me seriously and believe that the water is blue due to said food coloring.
