Green House Gases

What is meant by green house gases when we are discussing global warming? Please name as many as you can find.  Do we need these gases?

Yes we need green house gasses. Green house gasses beet up the sun rays.

Green house gasses trap the sun rays making the atmosphere warm therefore heating our earth creating global warming.

Casey K said...

We need Green House Gases so it won't be hot all of the time.

Leslie K said...

greenhouse gases are gases that we cause like emissions from cars. We need them and don't particular need them but they are useful in getting to where we go and they keep out earth temperature livable.

Mya N said...

We need greenhouse gasses so it won't be hot all year round.

Brendan S said...

Yes we do need green house gasses and here's why, they make it so that it is not always hot.

Ben S. said...

No, we don't need greenhouse gases because they are the reason there is global warming. Greenhouse Gases beat up Sun Beams!!!!!

Water vapor (H
2O)
Carbon dioxide (CO2)
Methane (CH
4)
Nitrous oxide (N
2O)
Ozone (O
3)
CFCs

Are some of the names.

Well Green House Gases trap the sun rays, it heats up the Earth making global warming. Global warming's bad. So I don't think we need green house gases.

Katie N. said...

Water Vapor, methane, and that's all I could find.

Leslie K said...

other gases are nitrous oxide, methane, and fluorinated gases

Blaze said...

Green House gasses are caused by car emissions and the o-zone layer allows more sun beams to enter and the green house gases traps in the infered beams heating up the Earth.

Green house gasses, are gasses that come from the sun, and stay trapped into the surface. Yes we do need green house gasses for extra warmth.

Green house gases are getting trapped in the Earth's atmosphere, causing global warming. I think we need them so it won't be hot year-round.

Greenhouse gasses are the things that thicken our atmosphere. The primary gasses in the atmosphere are Co2, water vapor, and methane. We don't need too much or too little.

keeps the earth nice and warm

Green houses trap the harmful rays which causes global warming. It is bad (global warming).

Ella T. said...

Green house gases causes global warming. Co2, No2, various compounds, Sf6, H2o (gas) O3, and probably more. (I obviously got this from the internet.) And yes we would need greenhouse gases, but at the moment, we have too much, and too much is a problem.

The most significant greenhouse gas is actually water vapor, not something produced directly by humankind in significant amounts. However, even slight increases in atmospheric levels of carbon dioxide (CO2) can cause a substantial increase in temperature.

Why is this? There are two reasons: First, although the concentrations of these gases are not nearly as large as that of oxygen and nitrogen (the main constituents of the atmosphere), neither oxygen or nitrogen are greenhouse gases. This is because neither has more than two atoms per molecule (i.e. their molecular forms are O2 and N2, respectively), and so they lack the internal vibrational modes that molecules with more than two atoms have. Both water and CO2, for example, have these "internal vibrational modes", and these vibrational modes can absorb and reradiate infrared radiation, which causes the greenhouse effect.

Secondly, CO2 tends to remain in the atmosphere for a very long time (time scales in the hundreds of years). Water vapor, on the other hand, can easily condense or evaporate, depending on local conditions. Water vapor levels therefore tend to adjust quickly to the prevailing conditions, such that the energy flows from the Sun and re-radiation from the Earth achieve a balance. CO2 tends to remain fairly constant and therefore behave as a controlling factor, rather than a reacting factor. More CO2 means that the balance occurs at higher temperatures and water vapor levels.

we need some but not to many so that we do not have global warming.

Carbon dioxide (CO2),Methane (CH4),Nitrous oxide (N2O),Fluorinated gases For each greenhouse gas, a Global Warming Potential (GWP) has been calculated to reflect how long it remains in the atmosphere, on average, and how strongly it absorbs energy.

Green house gases are carbon dioxide which comes from burning fossil fuels. We do not need green house gases in such large amounts as we have now. For that causes global warming and glaciers to melt leading to more water that also can possibly dry out.

john p said...

we may need some but only a little so the sun beams dont get killed and we have rotting corpses around the sun and so daddy doesent get mad when he puts a ice cube in his drink.

methane (CH4), which is nothing else than the cooking gas we use in our stoves,

Nitous oxyde (N2O), the scholarly name for..... laughing gas (which is not so much amusing here),

ozone (O3), which molecule comprises 3 oxygen atoms (the molecules of the "regular" oxygen gas have only 2 atoms of oxygen).

Green house gases are mad from co2 we think we may need some but only a little since the amount we have now are trapping to many uv rays.

green house grasses trap rase in the earth making global warming some gasses are cols co2 ch2 h2o and n2o !
