I've searched and searched, but I have yet to find information on the location of greenhouse gases (what layer of the atmosphere). I would also like to know if they are located at the bottom or top of that layer. (example= the ozone is mainly in the top of the stratosphere). The only information that I could find is regarding the composition of the "greenhouse gases" but not the actual location. Thanks.

Isn't water vapor technically a "greenhouse" gas? I would think greenhouse gases would concentrate at all levels of the atmosphere depending on its properties and how they react with other natural gases in those areas.

I don't think scientists really know where they are. They dont even have direct proof they exist.

They have direct proof look at this recent news article:

I hate the fact that the media does not publish their sources in details as I'd really like to find the journal that this research was originaly published in detail.

"Direct observational evidence", not 'proof'.

 

Ozone is formed by lightning, why don't we pass electricity into the atmosphere (O2) and get some ozone for preventing too much ultraviolet radiation?

Well, ozone is unstable as well. Even though we can make it, it would break down quickly. Also, the cost of electricity would be too much to make enough so that it would block the UV rays. Not a stupid question at all, I might add

there is a place in the USA (I don`t rem the name, but it`s close to a big city) in a valley, and they have very long thin wires that stretch for miles around, and they pass an electrical current through them to do exactly what you suggest on a local level, apparently the smog in that area claims many lives weekly and is extremely toxic, since these wires were put into use the smog levels droped as did the mortality rate

wind direction and other weather conditions are taken into consideration during use so that they know when and which wire arrays to activate, but yes, it DOES work )

Also, isn't ozone generated from car fumes? That was what I read in my sister's science book!

not that I`m aware of? NOx gasses sure and CO2 and water. O3 on the other hand???

if there were to be any, it would only be minimal trace generated by the spark plug discharge, but then alot of that would be used in combustion as O3 is alot more reactive than O2.

hmmm.... that's what I read. Must be pretty accurate though. Is it possible?

about O3 being emitted? we`ll chemicaly there would be trace amounts, but not in significant amounts to be an issue, the NOx gasses are the real PITA

would the book actually mention that O3 was produced as a result? Even though it is a trace?

to be honest, it would be very unlikely, but then again I don`t know what book or just how thourough it covers subjects? so that would be impossible to determine, I`de have thought it wouldn`t though.

Well, she is in year 5, and studies "discover the wonder". Could that help?

I`de be surprised if it mentioned Ozone (O3) outside of the context "Ozone Layer depletion"

Well, beleive it or not, she actually is learning that a poisonous gs is emitted from car fumes (along with the other gasses) and it is called ozone!

cool

she`ll be able to teach me about polycyclic hydrocarbons soon! (I still don`t beleive all that scare monger stuff about them with regards to BBQs) Paaahhh Foooey!

LOl! At the moment, she is with me right now and is reading the thread! She is asking me what polycyclic hydrocarbons are!

carcinogenics, apparently when meat fat hits the coals on a BBQ it gives off these polycyclic hydrocarbons and contaminates your food (we call it flavour, LOL).

tell her not to worry her head about it just yet, I`m more than sure she will learn about them sooner or later

LOL! Ok! Why do we call it flavour?

alot of these polycyclics are also aromatic "smokey" flavours that we can only get from a good BBQ most of the time

 

anyway, we`re drifting off topic a bit

yeah! So what have we decided about that ozone thing she is studying?

well. if you`re refering to your post #15 then yes in small amounts O3 is emitted, but I AM surprised that a year 5 book would go into such detail

 

(a pleasant surprise btw)
