Answer 2

Why is water blue?
Water is faint blue. Although water appears clear in small quanities (like a glass of water), the blue color becomes visible the more water we look through. Thus, deep lakes and seas are bluer than a shallow river.

Other factors can affect the color we see:

Particles and solutes can absorb light, as in tea or coffee. Green algae in rivers and streams often lend a blue-green color. The red sea has occasional blooms of red Trichodesmium erythraeum algae.
Particles in water can scatter light. The Colorado river is often muddy red because of suspended reddish silt in the water. Some mountain lakes and streams with finely gound rock, such as glacial flour, are tourquise. Light scattering by suspended matter is required in order that the blue light produced by water's absorption can return to the surface and be observed. Such scattering can also shift the spectrum of the emerging photons toward the green, a color often seen when water laden with suspended particles is observed.
The surface of seas and lakes often reflect blue skylight, making them appear bluer. [[[ Montana reflection.]]] The relative contribution of reflected skylight and the light scattered back from the depths is strongly dependent on observation angle.
(The Mediterranean Sea off the coast of Southwest Spain. The sea is vibrant blue because the intrinsic blue color of water is reflected back from the light-colored sand.)

Answer 3

You're seeing a reflection of the sky in the water.

Answer 4

blue is the color lowest on the color spectum meaning it has the shortst rays or something. when the sunlight reachest the o-zone layer its the last to defuse thus making the sky look blue. from there it hits the waters surface and makes it appear blue.

Answer 5

i could think of that good judgment could impose the obtrusive in this one and enable you recognize that water isn't colorless. that is blue. only no longer an exceedingly reliable blue till there's a great sort of water.

Answer 6

As well as the sky, algae, micro-organisms, impurities and silt all play a part in colouring water.

Answer 7

because it is a reflection from the sky. something about the way the light comes in

Answer 8

it's a reflection of the sky
