Snow is a good absorber of radiation, especially in the infrared range. This is because snow is made up of tiny ice crystals that are very efficient at scattering and absorbing light. When light hits a snow crystal, it is scattered in many different directions. Some of the light is scattered back into space, but some of it is absorbed by the ice crystal. The absorbed energy is then converted into heat, which can melt the snow.
The amount of radiation that snow can absorb depends on the size and shape of the ice crystals, as well as the wavelength of the radiation. In general, smaller ice crystals absorb more radiation than larger ice crystals. This is because smaller ice crystals have a larger surface area to volume ratio, which means that they have more surface area to absorb radiation. The wavelength of the radiation also affects how much snow can absorb. Snow absorbs more radiation in the infrared range than it does in the visible range. This is because the infrared range of light has longer wavelengths than the visible range of light, and longer wavelengths of light are more easily scattered and absorbed by ice crystals.
Snow can melt at 2 degrees Celsius.
The melting point of water is 0 degrees Celsius, but snow can melt at temperatures above 0 degrees Celsius. This is because snow is made up of tiny ice crystals that are not perfectly arranged. The imperfections in the ice crystals allow water molecules to escape from the snow and evaporate into the air. This evaporation process causes the snow to cool, which can slow down or even stop the melting process. However, if the temperature is above 0 degrees Celsius, the evaporation process will eventually cause the snow to melt.
The thickest ice in the world is found in the East Antarctic Ice Sheet.
The East Antarctic Ice Sheet is the largest ice sheet on Earth, and it contains about 70% of the world's freshwater. The ice sheet is up to 4,800 meters (15,700 feet) thick in some places. This is because the ice sheet has been accumulating for millions of years, and it has been compressed by the weight of the ice above it. The ice sheet is also very cold, with temperatures that can reach -90 degrees Celsius (-130 degrees Fahrenheit). This cold temperature helps to preserve the ice sheet, as it slows down the rate of melting.

East Antarctic Ice Sheet
The thickness of the East Antarctic Ice Sheet is not uniform throughout the ice sheet. The ice sheet is thinnest near the coast, where it is exposed to warmer temperatures and ocean currents. The ice sheet is thickest in the interior of the continent, where it is protected from the elements.
The East Antarctic Ice Sheet is a very important part of the Earth's climate system. The ice sheet reflects a lot of solar radiation back into space, which helps to keep the Earth cool. The ice sheet also stores a lot of freshwater, which is important for the Earth's water cycle. If the East Antarctic Ice Sheet were to melt, it would have a significant impact on the Earth's climate.
Yes, radiation emitted by the clouds and sky: the emissivity of snow is very close to one, therefore it absorbs almost all incoming infrared radiation in fact it is the infrared component in the solar radiation that explains why snow melts under bright sunlight when the air temperature is just. Snowfall as 'slight,' 'moderate' or 'heavy' when combined with strong winds, a snowfall can create blizzards and drifts. If the temperature is warmer than 2 °C then the snowflake will melt and fall as sleet rather than snow, and if it's warmer still, it will be rain.Snow is fancy looking ice that fell as individuals, but took a larger form as a whole when they landed and possibly accumulated. Ice is the solid state of water, which changes states at 0°C or 32°F. With that, the snow will melt above 32°, or freeze below 32°.The melting point at which ice — a solid — turns to water — a liquid — is 32°F (0°C). Invite the children to record their responses in their Ice Investigator Journals. A 2-degree rise in global temperatures is considered a critical threshold above which dangerous and cascading effects of human-generated climate change will occur. Freezing or frost occurs when the air temperature falls below the freezing point of water (0 °C, 32 °F, 273 K). The Antarctic Ice Sheet measures nearly 4.9 kilometers (3 miles) at its thickest point and contains about 30 million cubic kilometers (7.2 million cubic miles) of ice. If the entire Antarctic Ice Sheet melted, sea level would rise about 60 meters (200 feet). The EAIS is the driest, windiest, and coldest place on Earth, with temperatures reported down to nearly −100 °C. The EAIS holds the thickest ice on Earth, at 4,800 m (15,700 ft). It is home to the geographic South Pole and the Amundsen–Scott South Pole Station. At temperatures below 32°F (0°C), liquid water freezes; 32°F (0°C) is the freezing point of water. At temperatures above 32°F (0°C), pure water ice melts and changes state from a solid to a liquid (water); 32°F (0°C) is the melting point. The net-radiation intensity at seven other places on Cornwallis Island averaged about 150 W/m2 during the first week after melt started, which would melt 38 mm/day in rainfall equivalent. In this case net radiation alone would melt a one meter snow layer in ten days. Precipitation falls as snow when the air temperature is below 2 °C. It is a myth that it needs to be below zero to snow. In fact, in this country, the heaviest snowfalls tend to occur when the air temperature is between zero and 2 °C. Absorption of visible and near-ultraviolet radiation by ice is so weak that absorption of sunlight at these wavelengths in natural snow is dominated by trace amounts of light-absorbing impurities such as dust and soot.
