Global Warming is the gradual increase in overall temperature of earth’s atmosphere caused by increased greenhouse gases.

Which are the primary greenhouse gases in Earth's atmosphere?

• water vapor (H 2O), carbon dioxide (CO 2), methane (CH 4) and nitrous oxide ( N 2O)

• methane (CH 4), nitrous oxide (N 2O), water vapor (H 2O) and ozone (O3)

• water vapor (H 2O), carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2O) and ozone (O3)

• water vapor (H 2O), ozone (O3) and carbon dioxide (CO 2)
