Question

All of the following are greenhouse gases except_____________.
(a) Methane
(b) Carbon dioxide
(c) Ammonia

Answer 1

(c) Ammonia

The primary greenhouse gases in Earth's atmosphere are water vapour, carbon dioxide, carbon monoxide, methane, nitrous oxide and ozone. Greenhouse gases absorb the infrared radiations and increase the temperature. Without greenhouse gases, the average temperature of Earth's surface could drop to as low as about $-{18}^{\circ }C\left(0^{\circ }F\right)$. At present it is about ${14}^{\circ }C\left({57}^{\circ }F\right)$.
