Snow

A:

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.

  • 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.

  • 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.

  • 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.

  • 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 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 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 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.

  • Q: How are snowflakes formed?

    A: Snowflakes form when a droplet of water vapor freezes onto a dust particle or pollen grain in the sky, creating an ice crystal. As the crystal falls, more water vapor freezes onto the original crystal, creating new crystals, which form the six arms of the snowflake.

  • 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.

  • 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.

  • 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: What problems are common with Toro snow blowers?

    A: Some common problems with Toro snow blowers include unresponsive engines, the engine running but not moving and spark plug failures. Some of these problems occur as a result of human error, while others are caused by mechanical failures.

  • 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: What sort of substance can you put on a sidewalk to make ice melt?

    A: Salt and de-icers are substances that can be used to melt ice on a sidewalk. Salt can melt ice at temperatures up to 15 degrees Fahrenheit. For temperatures lower than 15 degrees Fahrenheit, specially formulated low-temperature de-icers can be used.

  • Q: Does it snow over the ocean ?

    A: Any major body of water, including the ocean, can experience snow. If temperatures are cold enough, snow forms over warm bodies of water as cold air moves into the area.

  • Q: Where does snow come from?

    A: 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.
