What are greenhouse gases and its effects?
When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. Greenhouse gases include water vapour, carbon dioxide, methane, nitrous oxide, ozone and some artificial chemicals such as chlorofluorocarbons (CFCs).
What are the 4 gases that cause 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).

Naturally occurring greenhouse gases include water vapor, carbon dioxide, ozone, methane and nitrous oxide, and together create a natural greenhouse effect. The greenhouse gases have three or more atoms in their molecules. CO2, H2O, CFC all have three atoms, while O2 (Oxygen) and N2 (Nitrogen) only have two.
Does NO2 cause global warming?
Non-methane Volatile Organic Compounds (NMVOCs) and nitrogen monoxide and nitrogen dioxide (collectively known as NOx) released from biomass combustion contribute to global warming by aiding the formation of tropospheric ozone (also known as photochemical smog), which is a greenhouse gas.
What country produces the most carbon dioxide?
Which gas is not in greenhouse?
Examples for greenhouse gases: Carbon dioxides, Methane, Chlorofluorocarbon, sulphur dioxide. Whereas oxygen, nitrogen and argon are not examples of greenhouse gases.
Are humans contributing to global warming?
Yes, by increasing the abundance of greenhouse gases in the atmosphere, human activities are amplifying Earth's natural greenhouse effect.
Do humans breathe out carbon dioxide?
All cells in our body need oxygen to create energy efficiently. When the cells create energy, however, they make carbon dioxide. We get oxygen by breathing in fresh air, and we remove carbon dioxide from the body by breathing out stale air.
