Greenhouse gases include
water vapour, carbon dioxide, methane, nitrous oxide, ozone
and some artificial chemicals such as chlorofluorocarbons
What gas has the greatest effect on greenhouse?
Water vapor
Encyclopædia Britannica, Inc. Water vapor is the most potent of the greenhouse gases in Earth’s atmosphere, and it’s sort of a unique player among the greenhouse gases.
What are the 5 main gases that contribute to increasing the greenhouse effect?
The main gases responsible for the greenhouse effect include
carbon dioxide, methane, nitrous oxide, and water vapor
(which all occur naturally), and fluorinated gases (which are synthetic).
What are the 6 main greenhouse gases?
- Water vapor.
- Carbon dioxide.
- Methane.
- Ozone.
- Nitrous oxide.
- Chlorofluorocarbons.

Which two gases are primarily responsible for the greenhouse effect?
greenhouse gas, any gas that has the property of absorbing infrared radiation (net heat energy) emitted from Earth’s surface and reradiating it back to Earth’s surface, thus contributing to the greenhouse effect.
Carbon dioxide, methane, and water vapour
are the most important greenhouse gases.
Why CO2 is a greenhouse gas?
As CO2 soaks up this infrared energy,
it vibrates and re-emits the infrared energy back in all directions
. About half of that energy goes out into space, and about half of it returns to Earth as heat, contributing to the ‘greenhouse effect.
What gases have the highest global warming potential?
Chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs), hydrochlorofluorocarbons (HCFCs)
, perfluorocarbons (PFCs), and sulfur hexafluoride (SF

) are sometimes called high-GWP gases because, for a given amount of mass, they trap substantially more heat than CO

.
Is NOx a greenhouse gas?
Nitrogen oxides (NOx) act
as indirect greenhouse gases
by producing the tropospheric greenhouse gas ‘ozone’ via photochemical reactions in the atmosphere. … Sources of NOx include fossil fuel burning, biomass burning and emission from soils.
Are VOCs greenhouse gases?
VOC compounds
VOCs have a direct effect by absorbing heat radiation from the ground, but their indirect contribution is more significant. They react with hydroxyl radicals (OH-) in the air, forming tropospheric ozone, which is a
greenhouse
gas.
Which of the following gases is not responsible for the greenhouse effect?
Solution: (d)
Nitrogen
is not a greenhouse gas.
What causes greenhouse effect?
Burning fossil fuels
produces huge quantities of carbon dioxide (CO
2
) which is a greenhouse gas. Carbon dioxide along with other greenhouse gasses such as methane, nitrous oxide and chlorofluorocarbons (CFCs) are changing the composition of the atmosphere and are adding to the greenhouse effect.
Which two gases are most responsible for the greenhouse effect quizlet?
The
carbon dioxide
traps the Earth’s heat like a blanket. *Carbon dioxide is an important greenhouse gas that helps to trap heat in our atmosphere.
Which two gases are primarily responsible for the greenhouse effect because of their ability to absorb thermal energy?
Major greenhouse gases include
carbon dioxide, methane, nitrous oxide
, and various synthetic chemicals. Carbon dioxide is widely reported as the most important anthropogenic greenhouse gas because it currently accounts for the greatest portion of the warming associated with human activities.
How does carbon dioxide affect greenhouse effect?
Carbon dioxide
controls the amount of water vapor in the atmosphere
and thus the size of the greenhouse effect. Rising carbon dioxide concentrations are already causing the planet to heat up.
