Why is the Sky blue?

Answer 1

Long ago when the world was being made, an evil sorcery began to take hold and soon darkness and rage consumed the new land; corruption ran free in pursuit of those true of heart. It hounded even the most altruistic souls and damned them to an abyss of depravity and perversion. All seemed loss to a world that had once seemed so promising. Until one day, a mighty warrior came forth to challenge the vile forces of malevolence. This warrior known to the others as Rowan, was among the bravest of the denizens of the new world and carried himself with a stoic and yet honorable visage that many of the other warriors envied. And so Rowan stood before the land and called out:
"I dare to oppose the force that has driven our land into a cradle of pestilence I wish to defeat he who has exiled the righteousness from the very souls of my people May he step forth and face me with the same audacity that fueled his unholy crusade darkness against our land!" As Rowan spoke these final words the ground began to rupture with cataclysms, the sky began to swirl with the intensity of a fierce storm, and suddenly a great voice bellowed, and it seemed as though the very land itself was speaking:
"Who dares to challenge I, the great Mektos?" The deep voice rattled the land as it spoke. The display of power, however, did not phase Rowan nor deter him form his goal, for he spoke back to it with the same courage and resolve as before:
"I Rowan, son of Allon, oppose your wickedness and vow to cleanse these lands of the evil you have brought forth upon them."
"Foolish mortal!", The voice began with a hint of amusement at the warriors brash act, "You haven't the smallest chance of defeating me, you would be lucky to walk away with your life from such a battle! Be gone now and I shall spare you the agony of death."
"I wish to challenge you, or will your cowardice prevent you from facing me?" At that the groung shook fiercely and mighty thunder rattled.
"No mortal dares insult me! I was willing to allow you to walk away from here with your life, but your foolishness shall cost you dearly. I accept your naive challenge, but before I allow you to have the honor of facing me in battle you must prove yourself worthy. I shall give you two tasks- one of strength and one of mind, but be it known that failure to accomplish one of the tasks will result in death; should you complete the tasks then you may face me in battle, but I warn you your efforts will be in vain."
"I accept the challenge." the warrior declared
"Then so be it." The voice replied, and with that the ground became still and the sky returned to it's idle gloom. The die had been cast.
That night Rowan made camp in the spot where they had spoken. He laid awake for many hours contemplating what fate awaited him with the morning, these tasks that Mektos spoke of intrigued him, he found that his thoughts had drifted to what they might hold; soon he was able to put his mind to rest and found himself on the threshold of sleep.
“Rowan...” A gentle voice hummed, it softly echoed and faded; the warrior shot up and drew a dagger from beside him.
“Show yourself!” He commanded
“There is know need to fear me, Rowan” The voice answered with the same soothing calm as before, “I am your ally.” These words made the warrior feel slightly comforted, but he still however, remained on his guard.
“If you are my ally as you claim to be than show yourself.”
“Alas, it is beyond my power at this time to do such a thing, but you must trust what I tell you.” Rowan decided to believe the voice for the time being, after all, it wasn’t the first occasion that he had encountered a disembodied voice.
“If you cannot reveal yourself, than I request to know who or what you are.”
“Yes, “ the voice began “I am Azraea, guardian and creator of the sky.” The warrior was shocked to hear this, but he kept his calm and responded:
“I have heard stories of the ancient gods, but I had believed that the forces of evil that now plague the land had abolished the creators long ago when they began their corruption.”
“Indeed we were banished, and even now we hang on only by a thread, a flicker of hope. That is why it is up to you, Rowan, you are the strongest and most cunning warrior in the land, and one of few who has yet to succumb to the forces of darkness.” The warrior took in this information, still surprised at the strange turn of events and yearning to hear more.
“This information you give me is insufficient, if I am to trust you than I require more.”
“You are right”, she began, “But time is against us so I must be quick. I am one of six creators; when this world was being made we were summoned to create and protect the six realms: sea, forest, tundra, sky, desert, and mountains. However, I expect you to know naught of these things, for when we were busy creating our realms an ancient foe of the gods, Mektos, brought his evil to the land. At the time we were foolish, we did not perceive Mektos as a threat and so we had no defenses against him, this was our blunder. At the very hour of creation, Mektos snatched the world away form us, his power and armies rebuilt after many millennia of banishment. I and the other five are imprisoned within Mektos’ magical stronghold, it is taking all the energy I have to communicate with you now. The only way to release us and cure the land is to injure Mektos in battle, that will weaken his magical grasp over the land allowing us to mend its wounds and vanquish the evil. But first, you must complete the tasks that have been delivered to you; unfortunately, I am unable to aide you in their completion, but I can however give you this.....” Suddenly a small, blue, glowing shard floated down into Rowan’s outstretched hands, he examined it with awe, never had he seen something so bright, so pure.
“What is this?” He inquired, his eyes still locked on the enigmatic trinket.
“A shard of my power, it is all I have left until Mektos is defeated, then all my power shall return, but until then this is all I have, and it is of more use to you than I right now. I must go now, but remember you are our last hope, Rowan, if you fail than our cause may be lost forever.” As Azraea’s voice dissipated, Rowan found the soothing calm of it had also disappeared, and he was once again alone. However, he found the company of the information he now possessed to be quite comforting.
The next morning the warrior awoke to the ground rattling and a voice calling from the sky:
“Come mortal and face your first challenge!” Mektos’ mighty voice commanded. Rowan walked outside of his small animal skin tent and saw two jars before him. “And now you shall prove your worth!” The deep voice bellowed, the warrior walked closer to the jars to further examine them, but as he reached out to touch the first a dark mist leaped out at his hand. Rowan leapt back and clutched his hand, he looked at it and saw that a small portion of his fleshed had been seared away. “A foolish blunder” Mektos said with some amusement, “One of these jars contains Illose leaf, a magical planet with the power to heal any wound, you must open the jar with the Illose leaf; should you choose correctly and burns you incur form the task shall be healed and you may move on to the next, should you choose incorrectly than the mist will consume your entire body at once and you will slowly burn to death with the intensity of ten thousands fires. And make your decision quickly, I am an impatient man.” Rowan pondered his choices, he knew he had nothing to go on, his decision would have to be completely random. He felt the shard glowing in his pocket, and felt it’s power coarse though his veins, the wisdom and cunning of it’s owner becoming his own; and an idea came to him. He reached out cautiously to the jar on the right ( the one he had not attempted to examine earlier) and put his hand over the lid, but did not open it, as he suspected nothing happened. Rowan caught on to the puzzle and reluctancy reached over to the jar on the left where he had be burned earlier and opened it as his hand was consumed by the black mist. He screamed out in anguish as he lifted the lid, and as he did the mist vanished and he saw the Illose leaf sitting in the bottom of the jar, but as he reached down to claim his prize he felt himself being sucked into the jar by some sort of arcane magic.
Rowan found himself on the dark, stormy, black shores of the ocean. He stood up and examined his surroundings curious and somewhat fearful of what might await him here- the final task, the task of strength.
“You may have proven yourself at the simple task I presented to you earlier” Mektos called from the air, ” I suppose I underestimated you in that regard-a mistake I do not intend to duplicate. But now we shall see how you fare against something of more challenge.” The warrior suddenly felt himself being lifted high into the air, and was thrust into the icy black waters, as he gained his balance and began treading the water he saw air bubbles on the water a few yards away and then a mighty Leviathan rose from the sea, covered in sleek scales blacker than the ocean and fierce yellow eyes, the beast bellowed as it saw the prey that had disturbed the surface.
Rowan gazed up at the ferocious monster, never in his life had he bore witness to something so nightmarish, so grotesque. He quickly drew his sword as he continued to keep his head above the surface, the warrior knew that he had no hope of injuring the beast- he would need to strike a fatal blow. Rowan dove beneath the surface and the extraordinary sea monster followed suit; it elegantly dove and twisted around the warrior as if it was taunting him, daring him to make the first move. The warrior knew it would not be long before he would have to return to the surface to get a breath of air, he would need to attack now or never. As the Leviathan continued to twist and slither through the water Rowan gauged the opportune moment and began to swim quickly toward the beast, as he approached he thrust his sword at the monster, as he landed the blow he realized that he was too late. His aim for the creatures throat had fell short of but a few inches, and the Leviathan, now irate at the human’s nerve, brought its gargantuan tail around and slammed it into Rowan, hurling him to the ocean’s floor. As he regained his balance he reached for his sword that laid barely within his grasp, the creature realized this and quickly made its way to the sword and knocked it far out of sight into the blackness of the water. Then, it lunged, mouth open and ready to strike at the warrior; Rowan felt dizzy form lack of oxygen, everything began to seem so surreal as he slipped into submission. As he was losing consciousness he felt the shard glow again, and again he felt it give him power beyond any he had ever felt before, he dodged the Leviathan’s unforgiving jaws and in an act of valor and bravery grabbed onto it’s large neck. The creature was taken by surprise and began violently writhing to shake off its attacker; the warrior knew that he would soon lose hold and if he did, he would most likely not find himself with this opportunity again. Rowan desperately reached for his dagger but quickly realized that it was missing from its scabbard, so he seized the only option he had left to him: he took the shard in his hand and thrust it into the Leviathan’s thick flesh. The creature cried out in agony, and the warrior lost his grasp and began sinking to the ocean floor, but before he hit the bottom of the icy depths, a flash of light exploded and he once more felt the arcane forces transporting him.
Rowan now found himself laying on a barren stretch of land, one that was equally disturbing as it was unfamiliar.
“So we meet once more.” Mektos’ now familiar voice resounded, “I admit, I did not expect you to make it this far, you are indeed a worthy adversary; but this is where it ends.” A crash of thunder shook the heavens, the clouds began to swirl down to the ground to a singular point; as abruptly as it had begun, the thunder ceased and the clouds lifted themselves back to the sky. But where they had gathered now stood something more frightening than death itself. Over twenty feet high, stood Mektos; his fearsome dark colored armor was accented by razor sharp thorns and had large metal spike protruding from the elbows and shoulders as well, and his back covered with lurid blades, his gruesome weapon was salient as any Rowan had ever seen, with its jagged edges and distinctness, it seemed to mock any other weapon ever forged. His face was but a mere shadow behind the mask he wore, but even still was enough to strike fear into the hearts of all who gazed upon him.
“Now foolish human, do not be so naive as to believe that your success in the minuscule tasks that I gave you will prove to be you ally in our battle. I am far stronger than any man or beast ever to walk this earth, do not be so credulous to think that you have even the remotest chance of besting me here today. However, I am not entirely without mercy, it would be a shame to lose a warrior such as yourself, so I shall offer you the unique opportunity to serve me and pledge yourself to the forces of enormity and cruelness forever. With this I shall grant you immortality making you even more powerful than you could have ever fathomed. What say you?” Rowan considered the tempting offer, but remembered Azraea’s words to him, he thought of her voice that had revealed the truth to him. All I must do is injure him the warrior thought to himself
“I shall never join you so long as the ancient ones live, and as long as I call myself a warrior.” Mektos looked shocked at the mention of the gods he held captive but kept his same face.
“Those whom you speak of are naught but cowards who surrendered their pathetic world to me when their demise was imminent. You no nothing of what they truly are.”
“I know that they a force goodness and nobility” Rowan declared with pride, “I know the truth, that you snatched the world form them before it was ever complete. But I intend to change that here today, I shall end your rule and bring the path of righteousness back to our lands.” Mektos chuckled at this seeming somewhat amused, but he spoke back abruptly:
“And what do you know of this altruism that you hold in such high esteem? What gives you the knowledge and wisdom to proclaim something evil? You proclaim my actions evil merely because you do not agree with them; our intentions, human, are not so dissimilar.”
“Enough of this delay!” Rowan interjected, knowing that Mektos was trying to sway his decision, “We shall fight now!”
“You only condemn yourself.” Mektos replied with a hint of dark humor in his words.
Rowan noticed that his sword had appeared at his side, of which he was thankful for, but the sense of gratuity vanished as the earth began to rumble and small yet fierce creatures began rising form the ground. The creatures had tarnished crimson skin and resembled some sort of reptilian monster, these were servants of Mektos, and the realization of his adversary’s sorcery hit him swiftly. Rowan began to fight of the hellish creatures with little difficulty, and a wave of confidence washed over him as their numbers dwindled, until they were gone. Mektos seemed more amused than put out by this and raised his hands high into the air and then thrust them forward, and suddenly hundreds of knife-like objects began hurling themselves at the warrior; but Rowan simply dodged them, with the occasional projectile grazing his arm, and made his way over to the dark sorcerer. The warrior felt insignificant standing before Mektos, but he still knew what must be done. Even if I die accomplishing it, he thought.
“You truly are foolish. “ Meaktos declared as he raised his mighty sword and hurled toward Rowan. The warrior evaded the blow and ran to the left; Mektos again attempted to strike him but Rowan dodged it again. The warrior’s plan was to strike low and hard, he knew that just one hit would damage the sorcerer’s power enough to allow the guardians to escape, but as he was formulating his attack, Rowan felt something painful hit him in his right side, Mektos’ blade had stuck him and the wound it inflicted burned with the white-hot intensity of any the warrior had ever felt. He cringed and cried out in torment, Mektos seized the opportunity to land a final blow, but Rowan was the quicker and attempted to ignore the pain; but it was to great to overcome and he found himself falling back to the ground.
“I shall give you one last chance, surrender or die!”
“Never!” Rowan yelled with all his strength.
“Asinine human! Look what you pride and valor has rewarded you with! I shall most enjoy disposing of you.” Mektos raised his blade high above Rowan and hurled it downward at him, however, the warrior would not give up and he quickly rolled toward the sorcerer and drove his sword into Mektos’ ankle with enough strength to fell even the mightiest of warriors. His opponent staggered backwards a few paces shocked that he had been wounded by a mere human, but he regained his balance and stepped forward toward Rowan who was lying there in anguish.
“You still seem to have that fatuous notion that I can be defeated by a mortal such as yourself! This mistake shall cost you your life!” And again Mektos raised his sword this time confident that Rowan was too incapacitated to strike him again, but like before he was unable to finish the task, this time for a different reason. Mektos turned slowly only to see the six gods he had held captive for millennia, standing before him.
“Now I see.” Mektos said in a calm tone, although fear, an emotion he had not felt in years was slowly taking hold of him, “Now I see where this human’s resolve originated, and now I understand how he came to know of the ancient ones.”
“And now we are at last free to stop you” Azraea interjected, “Your evil grip over this land expires today.”
“If only it were that simple” Mektos began, “You know as well as I that my power has grown considerably since your imprisonment, you should also know that not one of us standing here can die.”
“Death is not the only outcome.”
“An eternal battle, then?”
“No, we intend to banish you again, this time more permanently.”
“As you wish.” Mektos said with disgust, and the fight between them began.
Rowan heard the noise of their battle, but it all seemed like a blur to him, a faint whisper; their was another sound eclipsing that of the combat, a familiar and soothing voice that spoke gently to him
“The shard...” The voice uttered “You must cast the shard into the sky, Rowan. Only then can the wickedness be forever vanquished” Rowan understood. He grasped the entirety of the situation, here he was at the very apex of his quest, he struggled to find the strength to move, and slowly he crawled over to the glowing shard that had escaped from his pocket during the battle with Mektos. He grabbed the shard and thrust it into the dark sky above him, and with that the shard collided with the swirling clouds and in a flash of pale blue light its power blanketed the sky, it was the first time in his entire life Rowan had seen light. The derelict and destroyed land suddenly became alive with life and began returning to the state the gods had created it to be.
“No! This cannot be! I am immortal!” Mektos screamed, but his words were lost as the magnificent light took hold of him and with that he was gone, exiled forever.
In those last few moments of his life Rowan the great warrior had accomplished the goal he had set out to attain for years, and that children is why the sky is blue.

Answer 2

It has to do with the spectrum of colour on Earth, the oxygen in the air and the angle at which you view the sky.

To be precise:

Blue Sky is an Optical Phenomenon.

It is an event that can be observed which results from the interaction of light and matter.

The blue in the sky we see is scattered blue light.

The blue colour of the sky is due to Rayleigh scattering.

As light moves through the atmosphere most of the longer wavelengths pass straight through.

Shorter wavelength light is scattered by the gas molecules.

The scattered blue light is then radiated in different directions. It gets scattered all around the sky.

Answer 3

kcarter has it about right.
Also, you can have a quantum level explanation:
atmospheric gas atoms will accept the energy level in photons of blue light only. These electrons are boosted by the photon energy to an excited but unstable state. The electrons release the extra energy as a photon of blue light which is emitted in random directions. So, wherever you are you see these scattered photons giving the appearance of a blue sky.
This also gives the earth a blue colour when viewed from space.
As you have posted this on the religion page: doesn't this show how great is our creator God!

Answer 4

It's blue because we have evolved enough to see it that color. Go check history and the fact the sky was previously not blue and there were only 3-4 colors seen in a rainbow at one point in our development.

Next it will appear purple as we enter the new age. Enjoy!

Answer 5

the blue color of the sky is as a results of Rayleigh scattering. As gentle strikes through the ambience, various the longer wavelengths bypass instantly through. Little of the purple, orange and yellow gentle is bothered through the air. even if, many of the shorter wavelength gentle is absorbed through the gas molecules. The absorbed blue gentle is then radiated in diverse instructions. It receives scattered all around the sky. Whichever route you seem, a number of this scattered blue gentle reaches you. because you be conscious the blue gentle from everywhere overhead, the sky seems blue.

Answer 6

Sun light is a mixture of all the colors of the rainbow. The atmosphere is full of particles smaller than the wavelength of light. Lights is scatter from these particles in fact the shorter the wavelength the more it is scattered, blue and purple has shorter wavelengths than red and orange. That is why at sunsets the sun appears red because all the blue and purple light is removed by this scattering. While away from the sun at mid-day you only see blue because this is the light scattered from the sun in the atmosphere.
Hippoterry is confused between radiated emission and scattering, this is purely a scattering phemona.

Answer 7

Because light goes through the atmosphere and gets trapped in our atmostphere it than spreads into billions of particles on its way back out of the atmosphere. The blue light gets spread out and the other colors go through the atmosphere. Therefore reflecting a blue image and making it seem like the sky is blue when your really seeing blue light beams being spread out. neat huh?

Answer 8

The blue portion of the visible light spectrum is least refracted as it passes through the atmosphere.

Being that there is thus more blue light coming rather straight down (while the other visible light is more dispersed to hither and yon), the sky appears blue to us.

:-)

Answer 9

The sky is blue because of light filtering in the atmosphere but I think God made purty

Answer 10

The sky is blue because of Rayleigh scattering.

Answer 11

when the ultra-violet rays of the sun pass through the ozone layer, the sky looks blue,otherwise it is all black out there in the space.
