Shouldn't snow and ice be clear?

This has to do with the optical properties of water as it enters a new so-called phase; from liquid to solid. The liquid and solid state of water are two macroscopic phases, which means that the collective behaviour of the water molecules changes drastically as the temperature, in this case, drops below T = 0 degrees Celsius. As the molecules behave differently in the solid state than in the liquid state, e.g. they reflect light in a different manner due to their structural arrangement, it is not surprising that water has a different color when it freezes compared to when it is a liquid.

Probably just the weather changing quickly ? We had a thunderstorm a few weeks ago, except it was snowing with it. Really warm before it and really cold afterwards... I'm sure it's nothing to alarm yourself over.

Yes it will, until the molecules in the ice stop moving, then it will stay the same. This is called absolute zero, and is some ridiculously low temperature that nobody has ever been able to quite achieve yet.

At 10pm the snow was x + 8 is less than 24 inches.\nAt 7pm the snow was x inches, so it had to be less than 16 inches.

Clouds must form containing ice crystals which combine to form snowflakes - which means the relative humidity is 100% there and the temperature significantly below freezing (0 °C, 32 °F), -10 °C or colder usually. The relative humidity does not have to be anywhere near 100% at the surface (though will increase as snow falls thru the atmosphere), nor must the surface temperature be below freezing - in very favorable conditions can be 45-50 °F (I saw snow at 45° after a cold front October 12 this year, and have seen it as high as 49°). Yet surface temperatures close to or below freezing minimize melting, and if the air is too dry the snowflakes will sublime or melt & evaporate before they reach the ground.\n\nEven if those conditions are met, a significant above freezing  layer - especially in the clouds where the precipitation is developing - is usually sufficient to prevent snow. Even if the surface temperature is well below freezing in such a case, precipitation will usually be freezing rain &/or sleet.\n\nHere is an example from this morning of snow with relative humidity less than 100%:\n\nASUS45 KTFX 301519\nRWRMT \nMONTANA HOURLY WEATHER ROUNDUP\nNATIONAL WEATHER SERVICE GREAT FALLS MT\n819 AM MST THU NOV 30 2006\n\nNOTE: "FAIR" INDICATES FEW OR NO CLOUDS BELOW 12000 FEET WITH NO\nSIGNIFICANT WEATHER AND/OR OBSTRUCTIONS TO VISIBILITY.\n\n* THESE STATIONS ARE NOT UNDER NWS QUALITY CONTROL.

snow is formed by God while ice is formed by us surely there has to be a difference

Google Earth images have all been taken within the last three years.  Not all of the earth has been covered in high resolution images so some areas will be blurry.

i've never seen snow = (\n\nIt's rainy down here in florida.  the temperature has been fluxuating the past week...freezing cold one day and hot the next.  sux

I've heard that the sky turns a type of dirty greenish greyish colour before a severe hailstorm, or a tornado.  But I'd like to think that the sky would do that because of the types of clouds, and the absorption and reflection of light.  I've never seen it myself to say for sure. \n\nI've also been told that there are green flashes that apprear on the sea (but the sea level has to be right) around sunset.  I've never seen one of those either. Apparently, it's one of those must-see things.\n\nAnd then again, another place where greens exist is in the northern lights (Aurora Borealis)...  There are greens and they're gorgeous.  Now I've witnessed that, and it's simply GORGEOUS!!\n\nlike you said, there's always the good old rainbow!  I've seen that too :p\n\ncheers!!

We have definately seen Water and Carbon Dioxide ices on both the Northern and Southern poles of Mars, some ice may form in shadowed craters, particularly in the heavily cratered southern hemisphere of the planet.  Conditions may be right in some places to have an icy frost just in the subsurface, but more investigation is needed.

Could be an early sign of retinal detachment, glaucoma, or other serious eye disease. Have you been to the eye doctor? I'd say that would be your best bet. Start writing down when you experience the snow and try to pay attention to what happens just before & after the experience. This may give you clues as to if it's a precursor to something or maybe a reaction to something.

skin is primarily water so it stands to reason if too cold it will freeze as water does

an updraft of cold air freezes water droplets into crystle. All of them are 6 sided, and EVERY ONE of them is different - amazing eh.\n\nyou can go to http://snowflakebentley.com/snowflakes.htm for cool pics and \nhttp://www.kidzworld.com/site/p1587.htm\nto see how snow is formed.

Here in Canada the bikes are put up for the season since snow is around. Fall is only now getting cool which is unusual for us.Normally we would be under a foot of snow, but not yet. We normally clean the house Saturdays, and on sundays relax, walk the dog, have a drink by the fireplace, welcome friends who drop over and perhaps watch a movie all curled up together. Can`t wait for the snow so snowmen and snow forts can be built. We love tons of snow...hopefully we will see some soon...hey gotta have a white christmas right.

ttocsewol is sort of right but off by a little bit. The ice is anaerobic, meaning it has little or no air in its structure compared to regular ice. But the ice is actually only scattering blue light and absorbing the larger wavelengths (green through to red). The higher frequency blue wavelengths become more scattered the farther into the ice they travel, so the ice has to be thick to appear blue. If you chipped a piece off, it would be almost perfectly clear. Much clearer than normal ice, and this is becase as the ice crystals are compressed, they actually grow in size, which causes visible light to have a greater chance of passing straight through without being scattered.\n\nBoulder dust within the ice can also contribute to its colour.\n\nI live only a few hours drive from the Columbia Icefield, and I spent a day last summer walking up the Saskatchewan Glacier, which was awesome. Glaciers are one of my favourite things to visit. In fact, I spent all of last summer in the Rocky Mountains, and saw at least 50 or more large glaciers. Even flew over a bunch in a helicopter.\n\nI put a picture of me on the Saskatchewan glacier here:\n\nwww.8008rocks.com/DSCN2519.jpg

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

Salt will lower the freezing point of water. That is why the use in on the roads in winter.
