Snow forms in the atmosphere when the proper temperature and moisture conditions are met. For snow to materialize, temperatures must be below freezing, or around 32 degrees Fahrenheit, and there must be a slight amount of moisture present in the air. In order for snow to have the best chance of reaching the ground, temperatures must be at or below freezing.
Once snow crystals develop in Earth's atmosphere, they expand by merging with surrounding water droplets. Snow is much less likely to occur in areas that are dry and cold, since the formation of snow depends not only on the right cold weather conditions, but also on the presence of moisture in the air. The majority of snowflakes are less than 1/2-inch across, but they can form as large as 2 inches under the right conditions.Learn More
Snow, which is made up of millions of ice crystals and air pockets, reflects all of the wavelengths of light in the visible spectrum. When combined, the reflected light wavelengths create a white color. All objects in the world get their color based on which wavelengths of light they absorb and which ones they reflect.Full Answer >
Snow is made up of small ice crystals and is perfectly edible most of the time. The only time it is potentially dangerous to eat snow is when it is contaminated.Full Answer >
On average, snow weighs between 7 pounds per cubic foot and 20 pounds per cubic foot, according to North Dakota State University. The discrepancies can be attributed to the physical state of the ice, its depth and the atmospheric temperature; fluffy snow is light, while compacted snow is heavier.Full Answer >
