difference between snow&frost?

Snow is water molecules clinging to each other in the atmosphere, then falling to earth. Frost is water molecules freezing (thus clinging) to a foriegn solid mater.

Neither, it's an urban myth\n\nThey have 4 main words for snow\n\nMany of the words claimed to mean snow are wrong .... for example, people say they have a word for the snow they use for igloos ....... this is rubbish, the word they use literally means "materials for house" nothing at all to do with snow.\n\nInterestingly though, they have no word for bear, you can say polar bear as one word, black bear as one word, but not just bear.\n\nFish is another example, they have words for trout, salmon etc but no word for fish as a whole.

The warm front is moving into colder air. The moisture at the leading edge of the front freezes when it hits the cold air causing snow. As the front moves through, the warm air is increasingly higher in altitude which causes the falling moisture to warm up in the form of sleet then freezing rain then rain.\n\nHope this helps!

The key word is "winter" time.  During the winter, outside air leaks into a house (it must to make up for any air that is used in a furnace and goes up the chimney).  The outside air is very cold and can hold very little moisture (any excess would turn to frost (like on your car windshield on a very cold morning.)  Once the air is inside the house and heats up it is very dry (unless you add moisture using a humidifier).  Dry air permits a static electric charge to build up, especially when generated by friction, for examply when shuffling across a carpet or just the moltion within our clothes as we walk.  When we touch a good conductor such as metal, the excess charge drains off to a less charged body such as a stove and is often strong enough to see and feel as a spark.  If you rub a dry comb with cloth (perhaps silk) while your hands are dry, it can build up a charge strong enough to pick up bits of paper, but if you wet the comb it will not build up a charge.  If you dampen your feet or shoes or slippers, you also will likely not build up a static charge - although that would not be very practical.  You can increase the moisture in your house with a humidifier, but too much will merely coat the windows with hoarfrost.  Finding clothes less prone to static may help as well as selecting shoes with soles that rid you of the charge better.  Good luck.

Water vapor that has frozen.\nTidbit: Snow doesn't melt - it vaporizes, turning back into vapor as it heats up.

Before it begins to snow, the system begins to cool the air down to ground level.  As this happens, moisture in the ground moves up into the weather system, and eventually mixes with the already cold water, ect within the cloud.  As the snow begins to fall, the temprature drops for a short period of time, and then stabilizes. \n\nThis stabilization happens so that the snow can continue to fall without turning into ice.  On average, winter snow will fall between 14 F and 30 F.  However, it is possible for snow to fall at lower tempratures, however you will see an increase in temprature to have snow fall.\n\nNot all snow falls, however, fall within that temprature range.  Area's such as alaska, greenland, siberia, ect, can have snow even when it is much much colder.  However, the general rule still applies:  snow fall equels an increase in temprature untill a stabilization point has been reached.\n\nSnow that falls within the normal range is usualy wet snow, ie it is snow that is mixed with a bit of melted snow (water vapor), thus causing it to be heavy snow.\n\nSnow that falls below the temprature range tends to be dry snow, ie, snow that has completely frozen over.\n\nDry snow can be a major problem as it doesn't allow for the stabilization to occure at a quick rate, instead, blizzards, huge snow storms, ect, can take effect before the storm system actually stabilizes.\n\nHope that made sens&#92;e

That is a fantastic question.\nIt is a matter of humidity. The cold weather\nthat allows snow means the air is not humid\nenough to allow an electric current to travel\n(along the water vapor in the air) over the differently\ncharged clouds and sky. People who say temp are\nsort of right, but it is the low temp that leads to the low\nhumidity that causes the "problem".\n\nThanks for asking such a good question.

It depends on what you mean by "does it get warm?". See below.\n\nIt can snow even at incredibly cold temperatures as long as there is some source of moisture and some way to lift or cool the air. It is true, however, that most heavy snowfalls occur with relatively warm air temperatures near the ground - typically 15 F or warmer since air can hold more water vapor at warmer temperatures.\n \nWhen is it too warm to snow?  How does snow form if the ground temperature is above freezing?  Snow forms when the atmospheric temperature is at or below freezing (0 C or 32 F) and there is a minimum amount of moisture in the air. If the ground temperature is at or below freezing, of course the snow will reach the ground.\n\nHowever, the snow can still reach the ground when the ground temperature is above freezing if the conditions are just right. In this case, snowflakes will begin to melt as they reach this warmer temperature layer; the melting creates evaporative cooling which cools the air immediately around the snow flake.This cooling retards melting. As a general rule, though, snow will not form if the ground temperature is 5 C (41 F).

Of course snow and ice are both composed of H2O, water.  They are two frozen forms of water that depend on different crystaline structures.  Snow flakes consist of six-sided symmetrical crystals (no two alike) that grow dendritically (like the branches of a pine tree).  Ice is formed when heat is removed from water (as in a refrigerator) slowing down the vibrations of the water molecules until they can join and bond together in solid chains that use space less efficently than liquid water.  Therefore the ice is less densly packed than water and floats.  We know that 90% of an iceberg is floating under water and 10% above because ice takes up more room than the water that formed it.

It takes time to transfer the thermal energy to the snow.  Snow also has an insulating effect on lower layers of snow, making it difficult to transfer heat there, making snow more persistent than would be expected.

im not sure what u mean by elements. but when a cold front passes warm air is cooled. warm air is able to hold more water than cold thus when it cools it releases it water in droplet form or rain. ussually since cold is heavier the liquid rain with is higher than the cold goes through the cold air and crystalizes and falls as snow. it the cooling effect is too fast ant the droplets fuse and fuse until their weight makes them fall as hail.

snow is a form of precipitation and ice is frozen precipitation.

Although snow is made of ice, their coefficients aren't exactly the same because snow is a crystalized form of ice; therefore, snow has a rougher surface. I found a number for a ski board (waxed wood) on snow, which is .14. Plastic is similar to waxed wood, in a sense. I hope this number is more accurate, and good luck on your physics project.

Ok, water, ice, and snow are the same things. They are the same element (depending if they are different mixtures. Are you pregnant? Ive only known pregnant people to like water ir anything frozen so much. But anyways, H2O whether ice or snow, are the same exact things.

Snow Shower - A short duration of light to moderate snowfall. Accumulations of snow are possible.\n\nFreezing Rain - Rain that falls in liquid form and then freezes upon impact with the ground or an item with a temperature of 32 degrees Fahrenheit or less, possibly producing a thin coating of ice. Even in small amounts, freezing rain can cause traveling problems. Large amounts can pull down power lines and tree branches.\n\nSleet - Precipitation consisting of transparent pellets of ice, 5 millimeters or less in diameter. Also called ice pellets. Forms when snow enters a warm layer of air above the surface and melts and then enters a deep layer of sub freezing air on the surface and refreezes.\n\nSnow Flurries - Intermittent snowfall of short duration. No measurable accumulation of snow occurs.\n\nYour HW i guess? ;)

Well, the first question should be "Why is snow white?"  \n\nA beam of white sunlight entering a snow bank is so quickly scattered by a zillion ice crystals and air pockets that most of it comes zinging right back out of the snow bank. No one wavelength is preferentially absorbed or reflected, so snow is essentially the color of the sunlight reflecting off it -- white. \n\nThen, when the snow melts...it's a clear(ish - depending on the purity of the snow) liquid, and is absorbed into the surroundings, or maybe it evaporates.  Voila!  No more color.

Well, it depends.  Are you talking ground temperature, air temperature, cloud temp.?  The ground temp doesn't have to be below freezing.  However, the temp in the clouds has to be.  This temp is often colder than ground temp, which means that snow will form even when the ground temp is above freezing.  If the snow isn't warmed much on the way down, it will still be snow when it gets to the ground.  Typically, according to Wikipedia.org, snow will fall at temps of 35-40 degrees F. and below.\n\nA good counter-example would be sleet, which is snow that has partially thawed on its descent to the earth.  Another good counter-example would be to tell the person to pay attention to the temp the next time it snows.  I live in Indiana, and we get snow all the time with temps around 40 degrees F.  It's not uncommon at all.
