|
|
what are the four main green house gases |
fluorinated gases,carbon dioxide,nitrous oxide and methane |
|
|
what are the three factors that determine a gas's effect on climate change |
how much there is how long they stay in the atmosphere how affective it is |
|
|
how do u measure the 3 factors of effectiveness |
parts per milli,trilli,billi measured in years and measured in GWP(global warming potential |
|
|
how is water vapor different from other GHG(green house gas) |
The amount of water vapor varies very quickly because it goes through it cycle very fast |
|
|
what is a GHG |
Gases that absorb and release heat into the atmosphere because of the amount there is |
|
|
how are GHG connected to global warming |
Earth absorbs visible sunlight and turns it into infrared light,that infrared light leaves slowly because it gets absorbed by GHG.The more GHGs' there are the slower the infrared light releases,the higher earth's temperature goes up. |
|
|
what is GWP(global warming potential) |
the amount of heat that a gas can release or retain in an atmosphere compared to the strength and GWP of carbon dioxide over a time usually measured in years |
