How far are greenhouse gases from the surface of the earth?
Greenhouse gasses are all around us. In fact, you breathe out carbon dioxide every time you exhale, and when you drink water, you're conusming H2O, which in vapor form is also a greenhouse gas.
What greenhouse gas stays in the atmosphere the longest?
Carbon dioxide, the most significant man-made greenhouse gas, is the most difficult to determine. Most of it is absorbed into the oceans, but that can take up to 200 years.Methane is more powerful than carbon dioxide, but methane breaks down after 12 years.Nitrous oxide remains in the atmosphere for more than 100 years.CFCs (chlorofluorocarbons) and similar gases (Compounds containing chlorine and/or fluorine (CFCs, HCFCs, HFCs, PFCs)) can remain in the atmosphere for many years. The IPCC has a list at this link.Water vapour remains in the atmosphere a very short time, from hours to at most several days, before it falls as some kind of precipitation.
Why do greenhouse gases warm the atmosphere but other gases do not?
Greenhouse gases don't "warm the atmosphere". What they do is trap heat.Why is because that's the definition of "greenhouse gas". Okay, a little more detail: they're transparent to high frequency radiation (visible light and UV) but largely opaque to lower frequency radiation (like IR). So energy in the form of visible light gets to the surface just fine, but when it's time to reradiate it as heat, greenhouse gases block the emission of the lower frequency IR "heat" radiation.
Why does all snow not melt in the mountains?
At high altitudes, the air is so thin that the greenhouse effect of the atmosphere is not sufficient to keep the air warm enough to melt the snow most of the time.
How does the addition of more greenhouse gases over time affect earths average temperature?
Greenhouse gases absorb heat rising from the suface of the earth. The more greenhouse gases there are, the more heat is absorbed. This is what is happening now. By burning fossil fuels (coal, oil and natural gas), we are adding extra carbon dioxide to the atmosphere and this is causing global warming.
Which has the longest residence time on continents?
Lakes
What is the residence time of water in the atmosphere?
.024 years or nine days
If the total mass of N2 in the atmosphere is 3.87e21 grams or 2.901 moles based on the denitrification rate of 310e12 grams year what is the residence time of N2 in the atmosphere?
Residence time = 3.87E21/310E12 = 1.25E7 years
At what time did humans start to add lots of greenhouse gases to the atmosphere?
industrial revolution
How does the atmosphere trap heat on earth?
The atmosphere uses 4 different temperate layers to trap heat. yeah because if it didn't than we would be cold all the time.

How does the atmosphere impact the biosphere?
first guh its the weather climate
Which type of pesticide has the longest residence time in the environment?
Organochlorine pesticides, such as DDT, have been known to have a long residence time in the environment. These compounds are resistant to breaking down and can persist in soil, water, and organisms for many years, causing potential harm to ecosystems and human health.

What is Difference between residence time and space time?
Residence time is the time it takes a particle to complete the cycle. Space time is volume of the reactor over the velocity. If the volume does not change and the velocity remains constant then Residence time = space time, however, if there is a disturbance in the reactor (i.e., change in pressure, temp, ect.), then residence time does not equal to space time.
