Snow

A:

As of 2014, the book of Guinness World Records reports the largest snowflake to have been 15 inches wide and 18 inches deep, based on an eyewitness report in 1887. The report has not been proven, and scientists confirm that large snowflakes usually range from 2 to 6 inches wide.

  • How Much Does Snow Weigh?

    Q: How Much Does Snow Weigh?

    A: 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.

  • How Do Avalanches Happen?

    Q: How Do Avalanches Happen?

    A: Avalanches occur when snow builds up to unstable levels on a steep surface, causing it to slide and fall. This can be due to a lack of vegetation supporting the snow, multiple layers of snow or ice, an increase in temperature or too heavy a snowfall over a short period.

  • What Causes It to Snow?

    Q: What Causes It to Snow?

    A: Snow occurs when water droplets in clouds freeze, and these droplets then act as a nucleus onto which molecules of water vapor adhere, forming larger ice crystals. Once the growing snowflake is too heavy for the movement of air in the clouds to support, it falls to the ground. Snow can form in any clouds that are below freezing temperature but only does so under the right conditions.

  • What Causes a Snowstorm?

    Q: What Causes a Snowstorm?

    A: Snowstorms occur when the moisture in clouds freezes and falls to the ground, causing precipitation. The temperature at ground level must also be below freezing.

  • What Shape Is a Snowflake?

    Q: What Shape Is a Snowflake?

    A: While each and every snowflake can be generally said to be a hexagonal (six-sided) crystal, snowflakes come in many forms, from simple prisms and solid columns that look like rock crystals to the iconic and intricate flakes like stellar dendrites and simple stars. There are a variety of factors in play when it comes to the shape of each individual snowflake, including temperature, humidity and atmospheric pressure. A temperature difference of just a few degrees can mean the difference between one type of snowflake shape, such as a columnar needle, and another, such as a stellar plate.

  • What Percentage of Fresh Snow Is Composed of Air?

    Q: What Percentage of Fresh Snow Is Composed of Air?

    A: Fresh snow is generally comprised of between 90 and 95 percent air. The presence of trapped air makes snow a good insulator, so animals often construct snow caves in which to hibernate. The snow closest to the ground is warmest and stays insulated by the air composition.

  • How Many Sides Does a Snowflake Have?

    Q: How Many Sides Does a Snowflake Have?

    A: Though their crystalline structure may manifest in a variety of unique shapes and patterns, all snowflakes have six sides. Because the molecules that build up to form a snowflake are made of water, these molecules fit together in a specific and predictable way that will always result in a six-sided crystal. Water molecules may occasionally form 12-sided ice crystals, but this multiple of six is the only known exception to the six-side rule, according to NPR.org.

  • What Is "onion Snow"?

    Q: What Is "onion Snow"?

    A: "Onion snow" refers to the last snowfall of the winter season and is said to mark the beginning of spring. It received its name because onions are planted in early spring, and the later snow fall covers them, providing small portions of beneficial moisture.

  • Q: Why Do Snowflakes Have Six Sides?

    A: The six-sided shape of snowflakes is caused by the way water molecules bond with each other in cold temperatures. The water molecules attract each other so that they form a type of hexagon shape. When they hit a certain temperature, they expand and make a larger hexagon shape.

  • Why Are Blizzards Dangerous?

    Q: Why Are Blizzards Dangerous?

    A: Blizzards are dangerous because of freezing temperatures that are exacerbated by high wind, difficulties getting through heavy snow and the possibility of getting lost in blinding flurries. A person caught outside in a blizzard needs to seek shelter immediately.

  • Q: Can You List Five Kinds of Snow Crystals?

    A: Five kinds of snow crystals are simple prisms, stellar plates, stellar dendrites, sectored plates and rimed crystals. Snowflakes are formed when water vapor freezes in clouds then falls through cold air to the ground. Snowflakes are almost always six-sided.

  • Q: How Do You Cut a Snowflake?

    A: You can cut paper snowflakes into an endless number of designs by folding paper and cutting notches around the edges. Make holiday snowflakes with plain office paper, construction paper, card stock or designer paper. You need a pair of scissors and, if desired, glitter, sequins or other decorations.

  • What Happens When Snow Melts?

    Q: What Happens When Snow Melts?

    A: When the weather begins to get warm after it has snowed and the snow begins to melt, there are actually a number of complex and important physical processes taking place. Heat is absorbed and converts the snow particles into water, which then makes its way to the ground. A number of different important factors can determine the rate at which this snow melting process takes place.

  • How Do Snowstorms Form?

    Q: How Do Snowstorms Form?

    A: Snowstorms form when different temperatures and moisture levels mix in the air. When a mass of warm moist air moves over a mass of cold dry air, a front is formed, which results in rain. When the air chills to temperatures below freezing (0ºC, or 32ºF), the rain turns into ice crystals. As the ice crystals fall, the air temperature increases, causing the crystals to turn to snow.

  • Q: What Are Truck Plows Used For?

    A: Truck plows are used for private snowplowing, a necessary part of life in any area where municipal plowing services are not timely or a private driveway is too long to shovel alone. Truck plows are large, complex machines mounted on the front end of a pickup truck and adjusted via hydraulics.
