If the atmosphere of the Earth were several times thicker, would snowfall be white or a different color?

The colour of snow depends on the composition of the snow and not the thickness of the atmosphere. In some heavily polluted areas, black snow has been reported.

Snowball Earth is a term used to descirbe a situation in which the area of land on earth whihc is occupiued by ice increases to such.  The more ice there is the more reflection of the sun's energy there will be.  More reflection means the global temperature decreases, leading to more ice sheets and more reflection until... you guessed it, the entire surface is covered in ice.\n\nLandmass refers to the surface area occupied by land.  This may increase as fresh/sea water becomes ice and the sea levels decrease.  Not sure what else you are asking.\n\nBy the way, desertification is another procss by whish mre solar reflection occurs.  desertification if the cganging of farm/natural land into deserts, which are pale in colour and so reflect more light than the previous land type.

Well.. the sky would be all the area between the earth till what you would refine as outer space. so basicaly the hight of the gases around the earth would be the sky.. in other words the atmosphere.\n\nhave a look at the article below, devides the atmosphere into differnt stages, pick out what you belive to be the limit of the sky. and good luck to your Man :D

The whiteness of clouds is due to the tiny particles of water that make them up refracting the sunlight that enters them to make it appear brighter as it comes out. They are white because all wavelengths are allowed to pass through them; none are absorbed.\n\nThe fluffiness of some clouds is caused by the interactions of winds and pressures that force the water particles into a particular shape.

The answer IS NOT pressure. Pressure has nothing to do with temperatures at the north pole, or why polar bears are white!\n\nThe right answer is "NO"!\n\nSources:\nhttp://fun.egreetingsetc.com/2F/D/AI/index.shtml\nhttp://teensetc.com/0F/0D/BI/index.shtml\nhttp://phunpages.com/1F/D/AI/index.shtml

Why are clouds white, you say? Clouds are white because the rain and sleet inside of the clouds scatters all sunlight equally creating white light. The same is true for White Cloud toilet tissue. White light bounces off of the fibers of the tissue, which scatters light equally and absorbs next to none.

The atmosphere is the mixture of gas molecules and other materials surrounding the earth. It is made mostly of the gases nitrogen (78%), and oxygen (21%). Argon gas and water (in the form of vapor, droplets and ice crystals) are the next most common things. There are also small amounts of other gases, plus many small solid particles, like dust, soot and ashes, pollen, and salt from the oceans. The atmosphere is densest (thickest) at the bottom, near the Earth. It gradually thins out as you go higher and higher up. There is no sharp break between the atmosphere and space.\n\nThe blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by the air. \n\nHowever, much of the shorter wavelength light is absorbed by the gas molecules. The absorbed blue light is then radiated in different directions. It gets scattered all around the sky. Whichever direction you look, some of this scattered blue light reaches you. Since you see the blue light from everywhere overhead, the sky looks blue.\n\nAs you look closer to the horizon, the sky appears much paler in color. To reach you, the scattered blue light must pass through more air. Some of it gets scattered away again in other directions. Less blue light reaches your eyes. The color of the sky near the horizon appears paler or white.

It would be like Mars.  Mars has an atmosphere, enough that it has wind, dust devils and giant sandstorms.  However, there is not enough incoming solar radiation (aka insolation) trapped by the atmosphere to keep it warm.

it has to do with the refraction of light. as ice is denser that water vapour that makes up regular clouds it refreacts at differing angles and densities hence that is why it is green.

sorry but on earth our atmosphere acts like a lens (it magnifies)\nif in space, the sun itself would seem as a pale red star, if you could ask neil armstrong why the controversy, it would probably be because of what he saw ( or didnt see) that kept the hushh going. :)

clouds would be very pretty

Our atmosphere -- the gaseous envelope surrounding the Earth -- is composed of several gases, primarily nitrogen, oxygen, argon and carbon dioxide. Water vapor and minute bits of dust, salt and clay-silicate particles swirl about in the mixture.\nThe atmosphere has four vertical layers that radiate from Earth and vary by temperature and composition. Proceeding from the ground outward, they are the troposphere, stratosphere, mesosphere and thermosphere.\n\n\nAll of the “optical phenomena” – halos, sun dogs, sun pillars, coronas and rainbows – are produced at specific levels in the troposphere, which extends from the surface up to about 12 kilometers, eight miles or 42,000 feet depending on which measuring stick you pick. Here, the temperature decreases rapidly with altitude – averaging 59°F at the surface and a right chilly -69°F at 11 km. Commercial jets fly in the upper reaches of the troposphere.\n\n\nHigh-level cirrus clouds form in extremely cold air where water vapor condenses on tiny dust and salt particles to form ice \ncrystals.\nHence these are responsible for various phenomena circles aroound light emitting/reflecting bodies on the sky, and the rings are formed depending upon how the light gets scattered and the colours also depend on that.\nVR

Well snow is white because it is a frozen sliver of moisture.We christians accept white as a sign of purity.Interestingly if you watch snow falling,no two particles ever collide(till they reach the ground)If you stand underneath falling snow and look directly up,the falling snow won't look white(try it)

Both reasons are correct.  The UV rays have less "stuff" to travel through in the air and atmosphere, so they have a stronger effect.\n\nAlso the snow does have a reflective and intensifying quality that it passes to the UV rays.

It depends on the density of snow. New snowfall is typically between 7% and 12% of the density of water, which means 1 inch of snow is equivalent to 0.07" to 0.12" of rain; stated another way, it takes 8 to 14 inches of snow to equal 1 inch of rain.\nWind exposure often increases the density to 20% to 30% (1 inch of rain = 3 to 5 inches of snow). Higher density (heavier) snow typically results from warmer temperatures and/or winds while lower density (lighter snow) usually results from colder air with less wind.

That depends on how far they fall through the atmosphere, how moist the atmosphere is and the temperature gradient as it travels through the air. I've seen them so small they are barely visible, as balls of snow and as large as a half inch in diameter disks.

I agree! ‘More darker’. –10 points for grammar.\n\nAs far as the question, it’s all down to refraction and refractive indices.\nYou know snow? You know how it look white from a distance but when you look at it real close it’s made of clear ice? The snow look white because it’s made of lots of tiny ice particles. When light passes through snow it bounces off every which way instead of coming out straight. That bouncing around splits the light into its different colours, just like a prism or a rainbow. And because the light coming from the snow is every different colour it look white. \n\nSame deal with a tile. Putting it simply a tile is made up of lots of tiny clay particles all stuck together. On a fine scale it’s avery rough surface. When light strikes the rough surface it bounces off those clay particles in lots of different directions, producing a white light. White overlaying black produces a grey colour, which is of course not as dark as black.\n\nSo why does water (or polish) make it darker? Because water smooths out the rough edges. It’s like wall papering over all the cracks. Now when light strikes the tile it all bounces off in the one direction. No white light is produces and the tile appears to be black since less white light is emitted.\n\nYou can see the same thing when you wet peice of newpaer, which also goes a darker colour for the same reasons.\n\nYou can see the exact same effect in reverse when you scratch a polished or glazed black tile with steel wool. The scratched area becomes greyish in colour because the rough edges are splitting the light into white again. An application of polish will restore the original colour by making the surface smooth once again.\n\nIn short microscopic rough surface = white light, which makes a black object look grey. Water, polish, glaze etc. are transparent, but they coat the rough edges, thus removing them. No rough edges, no white light, no grey
