why is the sky blue?

Answer 1

The atmosphere has been kind enough to filter out all but the prettiest shade of pale blue for us to enjoy.

Wasn't that nice of Mother Gaia?

Answer 2

Well lucky for you we just covered this in my 7th grade Science Class this is pretty complicated so i suggest that you listen or read carefully.

Well to start it off us as humans we get basically all are energy from the Sun and that is put into the catergories of Infared, Visible Light (Colors of the Rainbow), Ultraviolet.

Now Infared can't be seen but is felt as heat, like of 3 heat transfers
Radiation: Means heat by electromagnetic waves; like a Heat Lamp or Transfer through the air.
Conduction: Is pretty much Heat Transfering by touch like touching a hot pot.
Convection: Is kinda complicated but it is Heat Transfer by fluid which could be getting heat from a furnace moves from place to place by gases or liquids. (sorry if this doesn't help much)
Visible light is the main answer to your question, well InfaRED has the longest wavelenghts and is close to RED which means it stays out on the earth longer but its not seen first, ulraVIOLET has the shortest wavelenghts but Blue has the shortest and that way blue is scattered throughout the Troposphere and is seen as blue unitl it soon fades leaving only half a sun and the colors red and orange *Hint* *Hint* Sunset.
Just know that i'm about 90% sure about there is indeed a low chance of me being wrong though.
P.S
The levels of the Atmosphere are
Troposphere 0-12km and that would be were the weather that we see comes to play.
Stratosphere 12-50km and thats were the Ozone Layer absorbs Ulraviloet radiation which is how people get sun burn
Mesosphere 50-80km this is were asteroids and meteoriods hit and start to brun up like in Star Wars 3 when they were in the crashing shuttle and it started to burn because it hit the Mesosphere
Thermosphere 80-to never ending, well the Thermpshere is just the place where the sun strike first so it gets everything we get first then slowly distributes it down the other atmospheres till it gets to us.
Ionosphere 80-550 km well the Ionosphere has Ions that reflects radio waves from satelites to Earth.
Exosphere Above 550 km this is were the Satelites are that's waves are reflected through the Ionosphere and down to Earth.

Oh Yeah and as for that little reflect off of water thing H*ll no its the opposite thats why your Kirkland or Aquafina are clear and not blue its because the Sun's rays hit the water spread out and once again blue is scattered causeing the sea to seme blue. There its doesn't have anything to do with the water reflecting to the sky oh and as proof the sky is some much bigger than all the oceans seas lakes in the world its impossible for them to reflect their little selves to the really big sky!

And for the guy who said dust particles he is right yet wrong thats for sunsets not for the sky being blue, but he really wasn't wrong he explained it better than i could.

Answer 3

I actually know that, African Sista, and so do ABC and Wesley B (if you cut away the excess).
The shorter wavelengths of light from the sun, ie. blue, get scattered more and the longer wavelengths (red) penetrate with less scattering. This is called the Rayleigh scattering effect. (See Wikipedia).
The scattered blue light gives the sky its ambient hue and the longer, penetrating red is why the sunset looks red. When the sun is setting, the light has to go through much more of the atmosphere than when it is more above us. This causes more of the blue light to be scattered, leaving proportionally more red light.

Answer 4

the reactions of the sun and how the sky reflects light

Answer 5

the sky is blue becausethe sunshine hits the ozon

Answer 6

If it were green we would not know if we were upside down or right side up.
But, as mentioned, the way light is refracted I guess.

Answer 7

dust in the air refracts sunlight, making it blue. when it sets, and the wavelengths are longer, it turns red/orange.

Answer 8

cuz it feels like it mannnn

dont be so sterotypical once the sky i saw was like yellowish mannn

Answer 9

cause the sky liked that colour....

Answer 10

Because it is the reflection of the ocean.
