Why is snow white?
Frequently Asked Questions about Snow CrystalsNo, it's not a white dye. Snow is made of ice crystals, and up close the individual crystals look clear, like glass. A large pile of snow crystals looks white for the same reason a pile of crushed glass looks white. Incident light is partially reflected by an ice surface, again just as it is from a glass surface. When you have a lot of partially reflecting surfaces, which you do in a snow bank, then incident light bounces around and eventually scatters back out.
Related QuestionsQ & AVisible sunlight is white. Most natural materials absorb some sunlight which gives them their color. Snow, however, reflects most of the sunlight. The complex structure of snow crystals results in countless tiny surfaces from which visible light is efficiently reflected. What little sunlight is absorbed by snow is absorbed uniformly over the wavelengths of visible light thus giving snow its white appearance.Related Questions
Hardrock Hundred FAQ (Frequently Asked Questions)was the driest year of the three previous runnings, and there were short snowbanks to cross over most of the major passes, with a substantial amount (thigh deep) below Virginus Pass. In '95 almost the entire course was under snow, and the run was cancelled because of it. Expect anything in between. We'll post periodic snow reports here, as the season progresses. You can also check them yourself. There are unseasonable bare spots on the peaks above Silverton.Related Questions
WHY NOT WHITE?
Frequently Asked QuestionsThe Miniature Schnauzer was developed to be an identical version of the Standard Schnauzer. The Standard Schnauzer has never come in the white color. Our history of the evolvement of the breed indicate that there probably were introductions of other breeds to reduce the size of the original breed. The originators of the breed recommended not breeding the whites and parti-colors that appeared. This was to preserve the breed as it was intended.

Online CookingWhile USDA bureaucrats drag their feet on closing key loopholes in national organic organic standards, retailers, wholesalers and major "organic" brands are continuing to sell milk and dairy products labeled as "USDA Organic", even though most or all of their milk is coming from factory farm feedlots where the animals have been brought in from conventional farms and are kept in intensive confinement, with little or no access to pasture.

TLC :: Little People, Big World :: FAQNo doubt some do. Many dwarfs, however, are proud of the role of dwarfs in history and in legend, going back as far as the art of ancient Egypt and Greece. What's important is that the average-size majority recognizes that LPs are fully capable people entitled to respect and equality.

Related QuestionsIs it ever too cold to snow?
Frequently Asked Questions about Snow CrystalsIn principle it can snow at any temperature below freezing. It snows at the South Pole even though the temperature is rarely above -40 C (-40 F). In more hospitable climates, however, it doesn't snow so much when the temperature is below around -20 C (-4 F). When a parcel of moist air cools, it starts producing snow before it gets that cold. By the time the temperature drops to -20 C, the snow has already fallen and the air is pretty dry.

Coconino National Forest - Frequently Asked Questions - Snow...Snowmaking occurs by producing a spray of water droplets that freeze before they hit the ground. Unlike natural snow that falls in crystals, machine-made snow is granular like lumps of sugar. Over time the particles bond to each other to create a texture that is similar to natural snow that has been weathered. The consistency of machine made snow depends on how much water flows through a snow nozzle.Related Questions

Frequently asked questions on snow sports injuriesI don't personally regard snow sports in general as "dangerous sports" at all and I don't think you should either - I hope once you have read through this website you will agree!

Related QuestionsWhy do snow crystals have six arms?
Frequently Asked Questions about Snow CrystalsThe six-fold symmetry of a snow crystal ultimately derives from the hexagonal geometry of the ice crystal lattice. But the lattice has molecular dimensions, so it's not trivial how this nano-scale symmetry is transferred to the structure of a large snow crystal. The way it works is through faceting. No long-range forces are necessary to form facets; they appear simply because of how the molecules hook up locally in the lattice (see Crystal Faceting for how this works).
