Snow

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 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 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.

  • How big can snowflakes get?

    Q: How big can snowflakes get?

    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.

  • 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.

  • Where does it snow in November?

    Q: Where does it snow in November?

    A: It snows in Europe, America, Canada and Japan in November. In Europe, it snows in mid-November in France, Sweden, Austria, Switzerland and Italy. In America, November snow falls mostly in New York, Colorado, Utah, and Minnesota. In Canada, snow falls largely in Ontario, Alberta, British Columbia, New Brunswick, Newfoundland, Manitoba and Quebec. In Japan, snow season starts in November.

  • 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 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.

  • What are the types of snowflakes?

    Q: What are the types of snowflakes?

    A: Scientists classify snowflakes into many different categories: simple prisms, stellar plates, stellar dendrites, fernlike stellar dendrites, capped columns, double plates, 12-sided snowflakes and rimed crystals. Despite the fact that all of the flakes form a hexagonal shape, none of them appear to be exactly the same. Classifying snowflakes is a difficult task. Classifications of snowflakes have ranged from six types to 35 types.

  • Q: How does snow form?

    A: Snow forms when atmospheric water vapor freezes onto a pollen or dust particle, which creates an ice crystal. As it falls, more water vapor freezes onto the ice crystal to create snowflakes.

  • 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.

  • Q: How does snow occur?

    A: Snowflakes form in the atmosphere when extremely cold water droplets form frozen crystals around tiny particles of dust or pollen. When these ice crystals fall closer to the ground, water vapor freezes onto the primary crystal and snowflakes grow larger with more crystals. This frozen water creates six-sided crystals.

  • Q: What is the difference between hail and snow?

    A: Hail is a form of precipitation that consists of hard spheres of ice that range from 0.2 to 6 inches in diameter. Snow is water that has crystallized in the atmosphere before falling.

  • Q: Why does snow burn?

    A: Snow appears to burn because of the chemical properties of water and the physical makeup of snow. Snow is loosely packed and contains more air than water, which creates a cushion that slows down the rate at which the icy structure melts.

  • 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.

  • 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: 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: Can it snow above 32 degrees ?

    A: Snow forms only when the temperature in the atmosphere is at least 32 degrees Fahrenheit and the air has at least a bit of moisture. In general, snow does not occur if ground temperatures are at least 41 degrees Fahrenheit.
