How the sea water looks blue color and why its salty?

Answer 1

The sea looks blue becuase it's reflecting off the sky. And the sky is blue becuase it's made up of alot of Oxygen3 molecules and Nitrogen3 molecules, when light goes through the molecules it acts kindof like a crystal and bends the light so that only certain wavelenghts get through, in this case it's the wave length that looks blue to the naked eye. Salt water: here's a link.

Here's a link for the blue explnation too.

Answer 2

Water, like pretty much any substance, absorbs light. There really isn't anything that is truly transparent. However, some things have a chemical composition and structure (the semi orderly to orderly arrangement of the atoms) that allows a high percentage of the incoming light to pass through without absorption or reflection. Even though most passes, some is "captured". The energy of the bonds in water are equivalent to the red end of the spectrum, that is, the red end of the spectrum is preferentially absorbed by the substance. The blue end is preferentially reflected or transmitted (the energy relations of the substance does not cause those waves to be absorbed). Basically, water is a weak light filter that lets blue pass but not red. The colors of essentially any substance is produced in this way, although emission of light as a bond or electron drops down an energy level is also important in some cases. So, water is blue. It is the nature of the substance. Pure water rarely exists, and many other substances have stronger absorption and reflection characteristics, so it is easy to change the colour of water by adding other substances in relatively small proportions. That is why real water sometimes can appear with reddish to greenish tinge or even strong color. It really isn't the water that gives those colors, it is the stuff in it, the impurities or suspended solids, that gives those colors.

Answer 3

I am taking a guess here The water had minerals of the
Earth in it and fish and the natural salt licks are different all over the world salt is needed and different to region and climate
Food Network had a whole segment on salt in different parts of the world. You know the phrase Worth Your Weight IN Salt was the payment for Roman Soldiers. President Kennedy made a few statements about the Sea and how everything came from the sea. The thought taste of our bodies produce a need for salt.
It clouds water non so clear but oxygen and healing properties may give the blue color.

and why the sea water is salty.............as

As rainwater passes through soil and percolates through rocks, it dissolves some of the minerals, a process called weathering. This is the water we drink, and of course, we cannot taste the salt because its concentration is too low. Eventually, this water with its small load of dissolved minerals or salts reaches a stream and flows into lakes and the ocean. The annual addition of dissolved salts by rivers is only a tiny fraction of the total salt in the ocean. The dissolved salts carried by all the world’s rivers would equal the salt in the ocean in about 200 to 300 million years.
A second clue to how the sea became salty is the presence of salt lakes such as the Great Salt Lake and the Dead Sea. Both are about 10 times saltier than seawater. Why are these lakes salty while most of the world’s lakes are not? Lakes are temporary storage areas for water. Rivers and streams bring water to the lakes, and other rivers carry water out of lakes. Thus, lakes are really only wide depressions in a river channel that have filled with water. Water flows in one end and out the other.

A final process that provides salts to the oceans is submarine volcanism, the eruption of volcanoes under water. This is similar to the previous process in that seawater is reacting with hot rock and dissolving some of the mineral constituents.

Answer 5

Sunlight is made up of all the colors of the rainbow: red, orange, yellow, green, blue, and violet. Some of the sunlight is reflected off the surface of the water, reflecting the color of the sky. Some of the sunlight penetrates the water and is scattered by ripples and particles in the water (this tinges the appearance of the ocean with the color of the particles). In deep water, much of the sunlight is scattered by the oxygen in the water, and this scatters more of the blue light.

Water absorbs more of the red light in sunlight; the water also enhances the scattering of blue light.

Salt:
All water, even rain water, contains dissolved chemicals which scientists call "salts."

The two ions that are present most often in seawater are are chloride and sodium. These two make up over 90% of all dissolved ions in seawater. By the way, the concentration of salt in seawater (salinity) is about 35 parts per thousand. In other words, about 35 of 1,000 (3.5%) of the weight of seawater comes from the dissolved salts; in a cubic mile of seawater the weight of the salt, as sodium chloride, would be about 120 million tons.

Answer 6

Why Is The Water Blue

Answer 7

hai friend
the sky makes the sea water to look blue and it is because water is a transparent media and it is not having any colour,
the main reason for the salty is because of many metals are formed under the sea and it is because of mixture of all the water and reactions in the sea base.

Answer 8

blue due to sky's reflection
and salty coz when rain comes down from mountains into sea they take some chemicals with it
and salt is one of that NaCl and other
and the second reason is that shells of animals are made up of chamicals when they decompose they make water salty

Answer 9

i guess it reflects the sky... why is the sky blue? i think the light from the sun is polarized into color blue..

salty? from dissolved minerals from rocks. they get dissolved by the water that runs to the oceans from streams...etc

Answer 10

the reflection of the sunlight from the water and its salty because of certain chemicals like chloride and sodium and 97% of the world's water is salty.
