The reason that the sky is blue is because the sunshine/sunrays reacts with the nitrogen molecules in Earth's Atmosphere scattering it-creating the 'blue' we see in the sky. This is a cemical reaction. I wonder how safe is it really to be outdoors during the day and how long people should be exposed to sunlight? Of course everyone needs sunlight to live be how much is to much especially considering the fact that the human body emitts it's own light. According to a website the amount of sun that's acceptable depends on who you are, where you are and what time of year it is.
When sunlight makes daytime-the blue sky, by this chemical reaction it does release toxins (nitrates) but so far I haven't been able to gather info on how much toxins (nitrates) are release and how detrimintal it could be to the human body. But I have noticed that there are air filters that are available to help clean the nitrates/nitrogen from the air during the daytime.

So the Sun is actually white in color and not yellow. Now i know why the world is so crazy and chaotic.
http://www.physicsclassroom.com/class/light/u12l2a.cfm
Technically speaking, white is not a color at all - at least not in the sense that there is a light wave with a wavelength that is characteristic of white. Rather, white is the combination of all the colors of the visible light spectrum. If all the wavelengths of the visible light spectrum give the appearance of white, then none of the wavelengths would lead to the appearance of black. Once more, black is not actually a color. Technically speaking, black is merely the absence of the wavelengths of the visible light spectrum. So when you are in a room with no lights and everything around you appears black, it means that there are no wavelengths of visible light striking your eye as you sight at the surroundings.
http://www.sciencemadesimple.com/sky_blue.html
On Earth, the sun appears yellow. If you were out in space, or on the moon, the sun would look white. Why? In space, there is no atmosphere to scatter the sun's light.
In ancient times the sun was Black. I'm willing to bet that if the sun somehow turns back Black that the world would be a more happier peaceful place.
http://en.wikipedia.org/wiki/Black_Sun_(mythology)
The Black Sun in Mesoamerican mythology has many mystical meanings, among them it is connected to the ? Quetzalcoatl and his ? in the Underworld through the west door after his diurnal passage on the sky. For the Mexicas there were two suns, the young Day Sun and the ancient Dark Sun. Some scholars regard the mythological Black Sun as the ancient female origin of all, it is both tomb and ? . This way, it is the oneness that uniformly integrates unawareness, death, and yet an expectation of fecundity.[1]

This article says that early morning sunlight can affect/distrupt the sleeping patterns of kids that get up early to go to school.

Lack of short-wavelength light during the school day delays dim light melatonin onset (DLMO) in middle school students.
The human body produces its own melatonin
starting two hours before bedtime, provided
the lighting is dim. This natural action is
known as “dim light melatonin onset”
(DLMO) and helps keep the body on a regular
sleep-wake schedule.Today, DLMO is
considered the best test available, a “gold
standard”, for measuring Melatonin levels and
Circadian Rhythm Disorders.
http://www.sleepontario.com/pamphlets/melatonin.pdf
Therefore, taking the DLMO test is very helpful
for discovering and understanding disturbances
in the human biological clock.
Lack of short-wavelength light in the morning has been shown to delay the circadian clock in controlled laboratory conditions. The results presented here are the first to show, outside laboratory conditions, that removal of short-wavelength light in the morning hours can delay DLMO in 8th-grade students. These field data, consistent with results from controlled laboratory studies, are directly relevant to lighting practice in schools -
UV wavelenghts are longer than UVB wavelenghts. UVB wavelenghts are healthier than UV but some studies show that it can still be harmful.
Surface plasmons can shrink light.
Surface plasmons have great potential for shrinking light. Since
a surface plasmon polariton (SPP) has a wavelength that is
shorter than the wavelength of light in vacuum, SPPs allow for
the miniaturization of optics: they have the potential to bring
the dimensions of optical devices down to the dimensions of
modern electronic integrated circuits.
Typical metals that support surface plasmons are silver and gold
Another reason to wear gold.

The premise of this topic is incorrect. The scattering that makes the sky blue is not a chemical reaction. The light doesn't change the chemical composition of the atmosphere at all.

This is what NASA says...Sun hits molecules in the Earth's
atmosphere and scatters off in all directions. The blue color of the
sky is a result of this scattering process.
When the sun hits the molecules, the molecules changes or moves. That's not a reaction?
The same thing happens when you turn on a light bulb.
Nitrogen is a gas. They're even beginning to use it as an fuel alternative.
http://en.wikipedia.org/wiki/Liquid_nitrogen_vehicle
A liquid nitrogen vehicle is powered by liquid nitrogen, which is stored in a tank. Traditional nitrogen engine designs work by heating the liquid nitrogen in a heat exchanger, extracting heat from the ambient air and using the resulting pressurized gas to operate a piston or rotary engine. Vehicles propelled by liquid nitrogen have been demonstrated, but are not used commercially. -

chemical reaction - a process that involves rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction.
The light scatters off the molecules but it doesn't change their molecular structure. It's called Rayleigh Scattering and it's a completely physical process not a chemical one.

nitpicking. When the sun rises numerous things happens to plants, animals and physical materials. photochromism is one example.
http://en.wikipedia.org/wiki/Photochromism
Photochromism does not have a rigorous definition, but is usually used to describe compounds that undergo a reversible photochemical reaction where an absorption band in the visible part of the electromagnetic spectrum changes dramatically in strength or wavelength. In many cases, an absorbance band is present in only one form. The degree of change required for a photochemical reaction to be dubbed "photochromic" is that which appears dramatic by eye, but in essence there is no dividing line between photochromic reactions and other photochemistry. Therefore, while the trans-cis isomerization of azobenzene is considered a photochromic reaction, the analogous reaction of stilbene is not. Since photochromism is just a special case of a photochemical reaction, almost any photochemical reaction type may be used to produce photochromism with appropriate molecular design. Some of the most common processes involved in photochromism are pericyclic reactions, cis-trans isomerizations, intramolecular hydrogen transfer, intramolecular group transfers, dissociation processes and electron transfers (oxidation-reduction).
Some people also wear photochromatic sunglasses to block light.

What is Photochromism?
Photochromism is a reversible process through which a material changes colour when exposed to light.1 The process has been applied in the optical industry since the 1960s to create lenses that respond to ultra-violet (UV) light via a chemical reaction by changing colour. The colour change, or activation, provides comfort
and protection to the patient in the presence of glare and bright light. It fades back to the original state when the exposure to UV ceases. When exposed to UV, photochromic molecules change their structure, a process known as activation, which causes the lenses to darken.1 UV disrupts the chemical bond causing part of the molecule to rotate into a new configuration. The molecule’s new flat structure absorbs light, thus darkening the lens.1 Newer technology has also enabled the manufacture of photochromic lenses that activate in the presence of low wavelength visible light in addition to UV.2

I'm not nitpicking. You're simply making statements that are untrue and using terminology out of place.
Again, Rayleigh Scattering is what is responsible for the blue sky. The process by which the blue light is scattered has no chemical affect on the particles in the atmosphere. So, it's not a chemical reaction. It is a physical reaction.
Photochromism has absolutely nothing to do with this discussion. We are not talking about whether or not light can be used to catalyze a chemical reaction. Of course it can, that's how photography had worked for decades. The premise of this thread at least based on the title is that the reaction that causes the sky to be blue is a chemical reaction and that that chemical reaction is carcinogenic. That premise is false because it's not a chemical reaction.
Now if you want to change the premise and simply state that sunlight itself can have effects on organisms that can be dangerous, that's fine. Again, that's nothing novel everyone knows about skin cancer and the part excessive sunlight plays in that, but that's completely different from the concept you opened this thread with. -
c'mon bro you killing me. i based it on this website...
http://answers.google.com/answers/threadview/id/406675.html
The daytime sky is
blue because light from the nearby Sun hits molecules in the Earth's
atmosphere and scatters off in all directions.
If the sun did not hit the nitrogen molecule it would not scatter. there are other gases in the atmosphere but the sunlight only changes the nitrogen. But maybe this website is wrong? Who knows? Things do not move on their on. in Philosophy there is always a first mover. -

This is the key point that you don't seem to understand. Hitting a molecule doesn't constitute a chemical reaction. By your argument, a bat hitting a baseball is a chemical reaction because the molecules of the bat hit the molecules of the ball. However, I'd hope you know that's not the case. A chemical reaction is characterized by a change in the chemicals involved. So if the light hit the atmosphere and caused the oxygen molecules to bond with the nitrogen molecules causing our atmosphere to be composed of nitrate molecules, that would be a chemical reaction. That's not what happens though. All you really get is a mechanical scattering of photons off of larger air molecules. Similar to what would happen if rolled a bunch of marbles towards a bowling ball. -
well i guess we'll just going to have to agree to disagree. peace.
-
lol There isn't really any agreeing to disagree on a matter of fact. You either accept your wrong and refine the point you're trying to make or continue to live in ignorance. Whatever floats your boat though.

c'mon now. there's no need for name calling. You're saying that for a reaction to occur a physical change has to happen. I'm saying that for a reaction to occur a physical change doesn't necessary has to happen. if you're sitting in a restaurant for example and a mouse came across the floor and you jump up; is that not a reaction?
Also is nitrogen was not in our atmosphere then the sky would be dark both night and day...check out the first 17 seconds in this video...

That should read if nitrogen was not in the atmosphere.

No, I'm saying for a <b>chemical</b> reaction to occur, there must be some <b>chemical</b> change in some or all of the matter involved. That's not my philosophy or opinion. That's the definition of the term. There is no debating that, which is why all this back and forth is ridiculous.
You're misusing terminology and then drawing bad conclusions from that misuse. Thinking outside of the box is fine, but even when you do that, there are rules. You can't wrongly call a cat a spaceship and then conclude you can ride a tabby to Mars. -
Pseudoscientific ?

i understand what you're saying but I still disagree about the mainstream definition of a chemical reaction. A chemical and a stimuli is enough for me to call it a reaction. But if you disagree it's cool. It won't affect me one way or another. This youtube video shows a similar effect to how the sunlight scatters the nitrogen atoms at sunrise. instead of sunlight they use some type of heat bolt.

aaaaaaaaaaaaaahhhhhhhhhhhhhhhhhh. You almost got me to concede defeat until I realized that the sun is made up of chemicals too. Duh!!
The sun is also composed of about 26 percent helium and trace amounts of other elements — oxygen, carbon, neon, nitrogen, magnesium, iron and silicon. These elements are created in the sun's core, which makes up 25 percent of the sun.
http://www.ask.com/question/what-makes-up-the-sun
The sun is made of mostly hydrogen and some helium. If you look at pictures up close taken by scientist, it looks like a big ball of fire. You can find more information here: http://www.nasa.gov/worldbook/sun_worldbook.html
just because it's 92,960,000 miles away doesn't negate the fact that it's a chemical. I mean if you put a cake in a fire burning wood oven the levitating ingredients in the cake batter will react to the heat in the oven and rise and not the actual flames itself.
http://chemistry.about.com/od/firecombustionchemistry/f/What-Is-Fire-Made-Of.htm
Question: What Is Fire Made Of?
You know that fire generates heat and light, but have you ever wondered what it is made of? Here is a look at the chemical composition of fire.
Answer: Fire is the result of a chemical reaction, called combustion. At a certain point in the combustion reaction, called the ignition point, flames are produced. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. Fire emits heat and light. In order for combustion and fire to occur, three things must be present: fuel, oxygen and energy (usually in the form of heat). -
