Why is mountain water blue?

Answer 1

The water may be reflecting the color of the blue sky (or the reds of sunset, or the gray of clouds), but an intrinsic blue color is caused by the refraction and scattering of visible light by the water. Different water qualities and depth can change the particular hue of blue. Very shallow water, as in streams, appears transparent.

Visible light is composed of all colors and the ocean water breaks the light into its different components (think of a prism). The colors on the red end of the spectrum (longer wavelength) are absorbed and the blue reflected. A similar principle (called the Rayleigh Effect) makes the sky appear blue in daylight.

Answer 2

Water looks blue because of the selective absorption in the red part of its visible spectrum.

This subject is a bit complicated and there are other factors, such as the colour of the sky. There's even disagreement sometimesbetween "reliable" sources.

Answer 3

Mountain water can appear blue due to the reflection of the sky's color mixed with the water's clarity and depth. The reflection of the sky can make the water appear blue, especially in mountainous regions where the water is typically cleaner and less polluted, allowing the blue color to be more pronounced.

Answer 4

The water in quarries are blue because of the surrounding limestone leeching into the water. These Blue hole as they are sometimes called are deadly and not for recreational swimming.

Answer 5

When mountain water is blue due to the way that it absorbs the sun's light. This is true for all water, the color depends on the sun's light.
