1. Water vapour, carbon dioxide, methane, ozone, nitrous oxide, CFCs and halons are responsible for global warming.

2. The largest sources of methane in the atmosphere are natural wetlands, rice paddies and livestock.

3. Nitrous oxides are released by the oceans, soils, biomass burning and the use of fertilizers.

Which of the statements given above are correct?

(a) 2 and 3

(b) 1 and 3

(c) 1 and 2

(d) All of these

Solution 1. (d) A greenhouses gas is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. The primary greenhouse gases in the Earth’s atmosphere are water vapor, carbon dioxide, methane, nitrous oxide and ozone.

Wetlands - Warm temperature and moist environments are ideal for methane production. Natural wetlands are important source of methane.

Rice Paddies - The warmer and moisture the rice field, the more methane is produced.

Animals - Microorganisms breaking down difficult to digest material in the guts of ruminant livestock and termites procure methane that is then released during defecation. Nitrous oxide is also released into atmosphere when fossil fuels and biomass are burnt. Nitrous oxide is emitted by bacteria in soils and oceans.
