SNOW

Snow is water that falls from a frozen cloud to become solid and like rain. Snow consists of water vapor particles which then cool in the upper air and fall to the earth into white, soft and crystal-like pieces. Snow is a solid object made of frozen water so that we can call it ice. Usually the snow will fall when winter arrives. Snowfall means rain that occurs instead of lowering water but lowering snow. Snowfall is a phenomenon that rarely occurs in one year in a non-tropical region, of course. Snowfall does not come every time, but only comes when winter arrives. Snowfall can last long or briefly. The temperature when snowfall also varies.

The process of snowfall is the source of water that is on the earth exposed to sunlight so that it evaporates, the water vapor gathers into the Earth's atmosphere. The collection of water vapor cools to the point of condensation (the temperature at which gas turns into liquid or solid) and forms clouds. When cloud formation, the mass is much smaller than air mass so that the cloud floats in the air. Water vapor continues to increase so that the mass also increases, so that when the air is no longer strong, the cloud will break by spreading pure water particles (not contaminated by other particles). Pure water does not immediately freeze at 0 degrees Celsius. To make pure air frozen it takes a temperature lower than 0 degrees Celsius right below the cloud. To form snow, it turns out that not only low temperatures are needed, when the particles of pure water come into contact with air, the water will be polluted by other particles that function to accelerate freezing and adhesion between water vapor so that impure water particles will join the particles others form larger ice. If the air temperature does not melt the ice crystals then the ice crystals will be far to the ground, and this is what we call snow.

At a certain temperature (called the 0 degrees Celsius freezing point, 32 degrees Fahrenheit) snow can melt and disappear. The process when snow changes directly into water vapor without melting first is called sublime. Snow with ice. Snow usually looks white but is actually transparent snow. Unlike ice, snow cannot be put into drinks. But snow is often used in sports such as skiing or playing snow sheets and making snowman.
