Question

Is the seas colour anything to do with the levels of salt or any other dissolved substance in it?

Answer 1

To know the answer to this question, you must first understand that sunlight is made up of different colours, from red, orange and yellow to green and blue. When sunlight falls on the sea, it is the colour blue that is reflected by the water most easily, giving the sea its blue colour.

Near the coast, sea water takes on a yellow or brownish tinge. This is due to the mud that rivers discharge into the sea, and the vast number of tiny plants and animals near the surface. When clouds hide the sun, the sea will look grey. Weather conditions can also change the colour of the sea.

Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.

Answer 2

From a distance on a clear day, the ocean does appear to be blue. However, this is only because water is so reflective, and it reflects the color of the sky. If you were to take a glass of sea water and hold it up, you would see it isn't blue, but somewhat grey. And yes, this has to do with the levels of salt and other substances in the ocean water. However, it isn't so much the salt as it is the other things in the water. And, indeed, there are lots and lots of substances in sea water. And, there is also lots of life in the water. Million or billions of different life forms exist in even a single glass of water. So, all together, this makes ocean water the color that it is.  

Answer 3

The seas' colour has mostly to do with the amount of plankton in them.

Answer 4

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.The Red Sea often looks red because of red algae that live in this sea. The Black Sea looks almost black because it has a high concentration of hydrogen sulfide (which appears black).

Answer 5

as far as i remember the sea gets its color from light that hits it

Answer 6

i don't know

Answer 7

The ocean appears blue because it is reflecting the light of the sky.  But if you grab a sample, it would look kind of hazy clear (it would not look crystal clear).  The haze is caused by dissolved salts and minerals, plankton, and other stuff found in the water.  If you go underwater, yes, the light turns blue because of all the stuff absorbing red light.  Pure water also absorb some red light as well.
