Answer 2

It is just a reflection of the sky............

Answer 3

wow i have never thought of that!!!! nice question and i really dont no

Answer 4

The ocean appears blue because of scattering of the sky.

As I explain..

I'm sure at your age you'll know the atmosphere is divided into several layers and you're familiar with incoming radiation. Our atmosphere and clouds reflect about 40 percent of the incoming solar radiation back out into space. The remaining obviously is 60 percent. That is responsible for warming the earth and atmosphere. About 20 percent of the 60, the ozonosphere and ionosphere are responsible for most of this absorption of radiation penetrates the lower layers where air is dense, some scattering occurs. Scattering is the bending of light rays in all directions by gas molecules. Some light rays are lost back to space. Since blue light is most affected by scattering, the sky appears blue which would be a "reflection" but in a sun set the sky is a mixture of several colors and only the surface of the ocean is reflected from the sky. So it's not just a reflection it also has to do with a triangular prism, space, and like I've said before scattering. So the wonders of the world isn't just as simple as a reflection there's always much more than what it may appear. For there was an intelligent designer.

Answer 5

That's correct. Blue rays travel faster, red rays slower. That's how they can gauge the areas between planets, constellations etc.

Answer 6

the sky is not blue or green or any colour its clear its just the reflection of the sky and trees.

see for yourself get a bottle and scoop some in it and see what colour you see

Answer 7

among other things it is a reflection. Why is the ocean blue?

When sunlight hits the ocean it is scattered by the water molecules that make up the ocean. Sunlight is made up of all of the colors of the rainbow (red through violet). Water molecules scatter blue light the most. This makes the ocean look blue.

Sometimes the ocean doesn't appear blue! Many parts of the ocean look green. This is because the blue we would normally see is mixed with the yellow coloring of floating plants...blue and yellow make green!

Another example of water not looking blue is the Yellow Sea. It looks yellow because of the great amounts of yellow mud carried into the Sea by rivers.

Answer 8

The story behind this phenomena is truly beautiful.

Do you know that water is transparent in nature? Yes, you are spot on my friend.

The case is that sunlight comes to the earth through a layer of dust particles which distributes the spectrum and out of that spectrum, the blue color is the dominant. When the light reflects from the sky, the intensity of the color increases which mystifies us that the sky and the water is blue. Indeed, that is the beauty of Nature. The sky is black and we do not really see two different skies at night and during the day. Actually, thanks to light for creating a such brilliant environment, plus the particles in the air.

Answer 9

no the sea isnt blue it is a reflection of the sky but since some of the sea is deper than other bits that makes it darker.

Answer 10

its blue in as our eyes see the reflected sunlight from it , just as we see the grass is green , from space the sea is blue , apart from a few parts that are very rich in plankton which reflect green

Answer 11

Sometimes it looks greenish in color, a reflection.

Answer 12

its a reflection.

get a glass, take a scoop of seawater - its NOT blue.

Answer 13

Water is blue in sufficient volume and clarity, like swimming pools. I suggest you see http://www.dartmouth.edu/~etrnsfer/water...

To all those maintaining it's a reflection, what about indoor pools?
