Why do glaciers sometimes have color?

Glaciers contain organic matter and minerals, experts have found that the substances in the glacier are the reason for the glacier's green color through spectroscopy and isotope measurement, and the various parts of the glacier contain different degrees of organic matter and minerals, there are no bubbles at the bottom of the glacier, so the density is small, sometimes it is knocked over, and the upper and lower parts almost absorb the strongest reflected blue light, so only green remains.

Glaciers are generally very large, just like the sea, and the sky is dyed blue. Volume or the angle of light has a big impact on its color, and it comes down to refraction.

It is mainly caused by the strong reflection of the glacier to the short blue-green light waves, and the relatively long light waves, such as red light and yellow light, are absorbed by it, and people turn blue-green when they look at it.

Color is the manifestation of the absorption of light by the substance, and the blue-green color may reflect blue light!

Glaciers are created by the recrystallization of snow, and the blue stuff of course reflects blue light.

Glaciers are inherently light blue.

The older the glacier, the bluer it gets.

Because the other colors are absorbed, only the blue is reflected.

Glacier white should be transparent, not pure white.

As soon as the snowflakes fall to the ground, they change, and as the external conditions and time change, the snowflakes will turn into spherical snow that completely loses its crystal characteristics, which is called granular snow, and this snow is the "raw material" of glaciers. After the snow becomes granular snow, over time, the hardness of the granular snow and the tightness between them increases, large and small particles of snow are pressed against each other, tightly inlaid together, and the pores between them continue to shrink so that they disappear, the brightness and transparency of the snow layer gradually weaken, and some air is also enclosed in it, so that glacial ice is formed.

The principle of glacial ice blue is the same as that of sky blue, both are light scattering effects, except that tiny bubbles in glacial ice replace gas molecules and small water droplets in the atmosphere. Imagine another "blue sky" hidden under an ancient glacier, and that's an amazing thing.

The ice we usually see is formed by the condensation of liquid water cooled below 0, butGlacial iceThe formation process is different, and its "previous life is not liquid water, but solid snow." In the polar and alpine regions, the cold climate means that precipitation throughout the year is solid, that is, only snow and no rain fall there.

The process of glacier formation.

Molecules actually absorb the light band very weakly, and the water looks transparent, for the water, when absorbing the red light in the sunlight is much more than absorbing the blue light, which is also due to the oxygen-hydrogen bonds in the water, so when the light passes through the ice, a lot of red light will be absorbed, and the blue light will be trapped outside, and the ice will become such a blue scene when the ice is thicker.

Glacial iceIt was milky white when it was first formed, and after a long period of timeGlacial iceIt becomes denser and harder, and the bubbles inside are gradually reduced, due to thisScattering of lightGlacial iceThere are tiny bubbles, and the red-orange light with a longer wavelength penetrates due to its strong diffraction ability, while the blue light has a shorter wavelength and is scattered, so that the wavelength of blue light is shorterGlacial icePresentBlue, which is presented in the sky and the seaBlueFor the same reason.

When the snow becomes a grain of snow, the particles of snow are pressed against each other over time, and the voids in it shrink and the air is enclosed in it, so it looks blue.

The reason why the ice of the glacier is blue is that the ice of the glacier is attached to the sea, which is a reflection of light, so it looks like the ice of the glacier is blue.

The ice of the glacier is transparent in nature, but because of the scattering of light, the glacier appears blue.

Because the ice of the glacier is very thick and refracted by the sun, it looks like the ice is blue, and this kind of ice is not the same as ordinary ice.

Glacier ice is blue because of the refraction of light.

The ice of a glacier is not formed by liquid water, but by solid snow.

As glacier ice forms, the small bubbles inside it become smaller and smaller, and when they are small enough to scatter sunlight. The longer wavelength of red orange light in sunlight is less easily scattered, while the shorter wavelength of blue and violet light is easily scattered, so that like the blue sky, the glacier ice turns a pleasant blue.

Glacial ice, pale blue, is due to the scattering of time due to the fact that over time, the glacial ice has become denser and harder, and the bubbles inside have gradually decreased. There are tiny bubbles in the glacier ice, and the longer wavelength of red and orange light penetrates due to its strong diffraction ability, while the blue light has a shorter wavelength and is scattered, giving the glacier ice a blue color.

The reason why glaciers will flow: glaciers are accumulated by snowflakes falling on the ground for many years, and because the snow will melt under the sun, but due to the influence of the surrounding low temperature, the melted snow will immediately condense into ice, and some snow will be compacted and condensed under the action of heavy pressure to form ice, when these ice continue to increase in volume and weight, and eventually form glacier ice, and because the glacier ice continues to develop, it will flow when the gravity is greater than the ground friction, but the flow speed of the glacier is very slow. It is usually only a few centimeters per day, and the most is only a few meters away.

Glaciers are a form of water that is transformed by snow through a series of changes. To form a glacier, there must first be a certain amount of solid precipitation, including snow, fog, hail, etc. Without enough solid precipitation as a "raw material", it is equivalent to "cooking without rice", and it cannot form a glacier at all.

In the high mountains, glaciers can develop, and in addition to a certain altitude, the mountains are not too steep. If the mountain peaks are too steep, the snow will fall down the slope and will not form snow and form glaciers.

As soon as the snowflakes fall to the ground, they change, and as the external conditions and time change, the snowflakes will turn into spherical snow that completely loses its crystal characteristics, which is called granular snow, and this snow is the "raw material" of glaciers.

Glacier ice is milky white when it first formed, and over time, the glacier ice becomes denser and harder, and the bubbles inside gradually decrease, slowly turning into crystal-like old glacier ice with a blue color.

Glacier ice is pale blue in color.

It is due to the fact that over time, the glacier ice becomes denser and harder, and the bubbles inside gradually decrease, which is the scattering of time. There are tiny bubbles in the glacier ice, and the red-orange light with a longer wavelength penetrates due to its strong diffraction ability, while the blue light has a shorter wavelength and is scattered, giving the glacier ice a blue color. This is the same reason why the sky and the sea are blue.

In other words, the perennial snow squeeze and snow water form a dense ice. Light with shorter wavelengths is reflected, so people see glaciers in a transparent blue color.

A glacier is a huge flowing solid, which is a huge glacier ice that is recrystallized and accumulated by snow in alpine regions, and the main factor of gravity makes the glacier ice flow and becomes a glacier. Glaciation involves erosion, transport, accumulation, etc., which create many terrains and form a variety of landforms in areas that have undergone glaciation. In addition, if the volume of glaciers is replaced by water, it accounts for all the amount of water on the planet except seawater.

In polar and alpine regions, the climate is very cold, and the snow is covered all year round, and when the snow accumulates on the ground, if the temperature drops below zero, it can be affected by its own pressure or recrystallized to produce snow particles, called granular snow (firn). When the snow layer increases, the snow particles are buried deeper, and the ice crystals become thicker and thicker, and the density of the snow particles increases due to the continuous decrease in the volume of air between the snow particles, making the snow particles more dense and forming blue glacial ice.
