why the sea color is appears as in blue color?

Answer 1

Because of the sea salt.

Answer 2

Sometimes, when the sky is overcast, the water appears more gray than blue. At least when I look at it. I believe that most of the abov e answers are correct and further propose that there are two reasons that water appears in the colors that it does. Many times in science we find that there are two competing answers to the same question only to find out later that both were right--it's a combination!

Some areas of the sea are more green than blue, some more blue, and the red sea is supposedly red! The water near Tahqumenon(sp?) Falls is like Tea, and many times when you fly over lakes and ponds on clear days you can see right to the bottom.

So here's why.

1. Water is reflective and reflects whatever color the sky over it is.

2. Water can contain impurities, like tanins or plankton, or have colorful dyes added to it, the list goes on.

When both are taken into account, we can explain why a tropical beach can go from being a brilliant sea green on a beautiful day to a maudlin grey once a storm hits.

Answer 3

You can ask that question is another way which is:why does the color of the sky appear blue??
The reason is because Light consists of 7 colors which are called the spectrum colors and when these colors are mixed together and are reflected to the sea's surface they give the color that you see.The sea is like a large water container so when you come to take a shower and you fill up the shower bed it becomes a large water container why does its color remain the same?( cos the spectrum colors are not reflected on it )

Answer 4

Below is a website about water that explains halfway down why water looks blue. Here also is an excerpt from that article:
http://en.wikipedia.org/wiki/Water

"Color
. . . This results in pure water appearing slightly blue when seen in mass quantities such as a lake or ocean. The blue color can easily be seen as one sees the blue color of the sea or a clear lake under an overcast sky, which means that it is not a reflection of the sky. In practice, the color of water can vary greatly, depending on impurities. Limestone turns bodies of water turquoise, while iron compounds turn it red/brown and copper compounds create an intense blue. Algae commonly colors water green."

Answer 5

the colour of the sea relies upon on the colour of the photons emitted by making use of the sea on your eye. that's a internet result. it is going to count on your distance from the sea and the attitude of the sea and solar on your eye (at the same time with time of day). solar astounding the sea is the two meditated or absorbed. mirrored image might ensue on the floor or after the sunshine has penetrated quite a few depths earlier being meditated. the quantity (and shade) meditated will count on the intensity reached and any tiny plant or animal life in the sea or sediment that has effects on absorption. If the sky is amazingly blue (cloudless?) the sea will mirror blue. It the sky is overcast the sea might seem greater greenish.

Answer 6

It is blue because of the pressure and the depth of the water. When the sea is very deep it affects the pressure and changes color.

Answer 7

The reflection of sky. Sky is blue is it not? The blue color of sky is due to the scattering of light. Why is it blue when observed from the space? The same scattering of light is the reason. Light can do miracles and illusions.

Answer 8

Because the light that reflects most is the blue color.

Answer 9

I liked of all the answers, but, there are places where the ocean color is GREEN. This could be because the organic composition (or contents) of the water (e.g. - near the Amazon River)...

So, arguments like reflection etc. are not good to explain what I can see in Fortaleza Iracema's beach! The water is (beautifull) green.

Answer 10

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.

Answer 11

The sea colour usually reflects the colour of the sky
