Question

The major green house gases are
A. CH₄, N₂, O₃, H₂O
B. CO₂, CH₄, CFC, O₃
C. N₂, O₂, H₂O, CO₂
D. He, CH₄, N₂O, H₂

Answer 1

Answer:

co2, ch4 , cfc,o3 are green gasses

Answer 2

B. CO₂, CH₄, CFC, O₃

Explanation:

The primary greenhouse gases in Earth's atmosphere are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFC), perfluorocarbons (PFC) and sulphur hexafluoride (SF6). HFCs and PFCs are also CFCs. Of these six gases mentioned above, three are of primary concern because they are closely associated to human activities.

So option B is the answer as it lists out carbon dioxide, methane, chloroflurocarbons and ozone.
