How was the sky made/  where did ALL of the atmosphere come from?

hi there i am glad you will explain the scientific way it is thought the earth was made. so here it goes from a biochem major to an awesome parent\nthe sky is blue because of light refraction that occurs when light from the sun penetrates through water droplets. these droplets are H2O and the bonds bend the light in such an angle that only the blue light is visible and the other 6 colors just are seen as white light. the earth's size actually made it have the proper gravitational pull on objects. thus keeps the molecules from excaping into space or from them falling to earth and liquifying or becoming low lying gases. the atmosphere actually came about when the first photosynthetic bacteria eavolved the ability to use light to "power" their energy cycle. they absorbed inorganic molecules like carbon dioxide and the by product was Oxygen. yes what we need is actually the waste of photosynthetic organisms. once the oceans became oxygen saturated the oxygen was able to make its way to the up since it was not inside of the water it became lighter and able to "float up" but not all the way out into space because of the gravity. this led to the development of the ozone layer and its protective properties. \n\nyeah i guess that science does take all the mystery and magice away from it but i think that knowing the actual way things came about brings more opportuinites to learn why these things happen. hope this helps any ?s email me at Rookiejc19@yahoo.com\n\nsorry about the bad grammer and such its pretty late and haha i should be sleeping.!!! goodluck

Atmosphere doesn't produce them it's just heated air rising up, and a very large area, like a desert, it's so dense that it create a mirror effect, look like water...

You guys got a lot of it, but the sun is actually green. The atmosphere absorbs much of the light to make it more of a yellowish white light. Pollution and the ozone layer trap and absorb the green light that the sun produces. Then you see what you see. (were you looking at the sun??? :)

The sky is (roughly) that part of the atmosphere or of outer space visible from the surface of the earth (or any other planet; see Skies of other planets). Birds, airplanes, and kites are often considered to fly in the sky. It is difficult to define precisely for several reasons. During daylight the sky has the appearance of an opaque blue surface, but this is the result of the air scattering sunlight. [1]There is no "blue object" above the earth in any normal sense, so it is hard to say what object the sky is. The sky is thus sometimes defined as the denser gaseous zone of a planet's atmosphere. At night the sky has the appearance of a black surface or region scattered with stars. But if we then say that the sky is the entire visible universe, it would not be the same thing we see during the day. The color of the sky is a result of diffuse sky radiation. On a sunny day the Earth sky usually looks as a blue gradient — dark in the zenith, light near the horizon (due to Rayleigh scattering). It turns orange and red during sunrise and sunset, and becomes black at night.\n\nDuring the day the Sun can be seen in the sky, unless covered by clouds. In the night sky (and to some extent during the day) the Moon, planets and stars are visible in the sky. Some of the natural phenomena seen in the sky are clouds, rainbows, and aurorae. Lightning can also be seen in the sky during storms. As a result of human activities, smog during the day and light radiance during the night are often seen above large cities (see also light pollution).\n\nIn the field of astronomy, the sky is also called the celestial sphere. This is an imaginary dome where the sun, stars, planets, and the moon are seen to be travelling. The celestial sphere is divided into regions called constellations.\n\n\nSky in religion\nMany cultures ascribed strong religious qualities to Earth's sky, believing it to be the home of the heavens and various deities. Among the Chinese, in certain situations, sky means god. For example, people may say "They became friends after several fights: this is the idea of the sky" or "Why does the sky always fool me?" Some religion and art historians believe that in Christianity, in particular, the connection between heaven and sky arose because of a medieval painting technique, where different places were drawn separately on the same picture. Heaven, a different and more important world, was usually painted above the earthly world and was separated from it by clouds.\n\n\nExpressions\nA pie in the sky is something that is wanted very badly but is unobtainable. \nWhen someone's assumptions or premises concerning a particular subject seem to be radically different from everything you know and recognize about the world, you wonder what color the sky is in their world. \nSimilarly, because the blue hue of the sky during daytime is such a universally observed and understood phenomenon, people say "as sure as the sky is blue" to mean that something is an indisputable fact. \nBlue skies are evoked as a symbol for good times, optimism and emotional peace. \nTo be sky-clad means to be in the nude. \nSimilarly, to go skying is a euphemism for stripping or streaking. \nTo show that there are no limits on what we can discover or accomplish, you can say, "The sky's the limit!" \n"Blue sky thinking" means coming up with a host of ideas without being restricted to what is practical (similar to brainstorming); in particular, an optimistic assumption is made that there will be no obstacles or opposition to implementation of the ideas. \n"The sky is falling" is a common expression that is used when any sort of disaster is occurring. This came from the fable Chicken Little

Without an atmosphere, our sky would be black witha bright sun in the middle. That is because all teh ligt comes from teh sun. When a planet has an atmosphere, the light scatters of teh nitrogen molecules in teh air. Thin of it as light hitting a molecule and bouncing off in all directions. That way light that is not directed towards us gets redirected by teh scatering so light seem sto be coming from all parts of the sky.\nScattering intensity increases with shorter wavelenght, so blue light gets scattered the most. (actually UV gets scattered even more so the sky is brighter at UV frequencies)\nAt sunset, the sunlight has to go through a lot more atmosphere then at noon. So scattering increases so much that only red light is left.\nTry it for yuorself:shine a flashlight at a glass of milk in teh dark and see the milk tunr blue or red

from trhe sampels of amber that was formed 100's years ago.some of it contained sampels of air of that age it is said that earth at that time had 30%oxygen in its compostion

The Earth's atmosphere has no definite boundary, slowly becoming thinner and fading into outer space. Three-quarters of the atmosphere's mass is contained within the first 11 km of the planet's surface. This lowest layer is called the troposphere. Further up, the atmosphere is usually divided into the stratosphere, mesosphere, and thermosphere. Beyond these, the exosphere thins out into the magnetosphere (where the Earth's magnetic fields interact with the solar wind). An important part of the atmosphere for life on Earth is the ozone layer.\n\nThe atmospheric pressure on the surface of the Earth averages 101.325 kPa, with a scale height of about 6 km. It is 78% nitrogen and 21% oxygen, with trace amounts of other gaseous molecules such as water vapor. The atmosphere protects the Earth's life forms by absorbing ultraviolet solar radiation, moderating temperature, transporting water vapor, and providing useful gases. The atmosphere is one of the principal components in determining weather and climate.\n\nBecause hydrogen gas is light and based on Earth's mean temperature, achieves escape velocity, unfixed hydrogen leaves the Earth. For this reason, the Earth's environment is oxidizing, with consequences for the chemical nature of life which developed on the planet.\n\nYou could get more information from the link below...

The Sun.\n\nEDIT: Yes, what other people have said about the Earth's tilt and whatnot are true in that they affect the atmosphere, but you asked for the source of energy. That is solely the Sun.

How scientific do you want it?\n\nBasically, air circulates the earth.\n\nThis air has different temperatures in different places.\n\nThe different temperatures cause different pressures of air masses.\n\nBecause of this air flows around air masses due to the pressure gradient between different masses.\n\nThis air flow drags air of even higher temperature differences into contact.\n\nDifferent air temperatures meet causing one to rise over the other, as this rising air goes up it cools and causes clouds (These areas where air masses join are the fronts on a weather map).\n\nThese clouds then produce rain.\n\nThat rain changes temperatures, more air masses are drawn into contact, and the cycle repeats.

Most of Earth's water condensed out of its early atmosphere, and that atmosphere came from world-wide volcanic eruptions. So, ultimately Earth's water resulted from volcanic activity, although much of it also comes from comets that entered our atmosphere.\n\nGod should be spelled B-I-G B-A-N-G\nPBrax@netscape.com

Mercury has no true atmosphere.  It only has trace amounts of whatever gases are present.  See the given link.

That's a good question. I'm quite sure "God made it" isn't the answer you're looking for, especially since you posted this in the science section. \n\nReligion seems to have all the answers, but those answers never satisfy the appetite of curiosity and learning. Below are several different worded versions of the same basic theory of how the Earth (and other planets) formed. \n\nBe sure to check out the sources.\n\n1. The planets formed from the material left over as a result of our sun's formation. As the nebulous cloud condensed and began to rotate, most of the gas condensed into what is now our sun. The remaining material formed what is now the planets and the other bodies in our solar system.\n\n2. The prevailing theory is that they are formed from those remnants of a nebula that do not condense under gravity to form a protostar. Instead, these remnants become a thin disc of dust and gas revolving around the protostar and begin to condense about local concentrations of mass within the disc. These concentrations become ever more dense until they collapse inward under gravity to form protoplanets. When the protostar has grown such that it ignites to form a star, its solar wind blows away most of the disc's remaining material. Thereafter there still may be many protoplanets orbiting the star or each other, but over time many will collide, either to form a single larger planet or release material for other larger protoplanets or planets to absorb. Meanwhile, protoplanets that have avoided collisions may become moons of larger planets.\n\n3. The most widely accepted model for the origin of the Solar System is called the  nebula theory. Most generally phrased, the theory states that the Solar System condensed from a large, lumpy cloud of cold gas and dust.\n\n4. Solar Nebula Theory

Our sun began forming within an immense interstellar cloud of drifting gas and dust. Inside this cloud (called a 'nebula') were regions of relatively high density where gravity began drawing together bits and pieces of the gas and dust. Over several million years, this spherical region became denser and denser which caused its central temperature to rise. Finally, some 4.5-billion years ago, the temperature was hot enough to start nuclear fusion. Our sun was born.\n\nGod should be spelled B-I-G B-A-N-G\nPBrax@netscape.com

The sun is only about 4.5 billion years old.  The cloud of gas and dust that it formed out of was probably huge, though.

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
