Question 1

A facilities manager is comparing the 100-year global warming potential (GWP) of gases emitted from site operations. Which of the following gases has the HIGHEST 100-year GWP?

Carbon dioxide (CO2) Methane (CH4) Nitrous oxide (N2O) Sulphur hexafluoride (SF6)

Correct Answer:

Sulphur hexafluoride (SF6)

Question 2

Within the nitrogen cycle, which process converts ammonium (NH4+) into nitrate (NO3-) that plants can readily take up?

Denitrification Nitrification Nitrogen fixation Ammonification

Correct Answer:

Nitrification

Question 3

What is the principal mechanism by which chlorofluorocarbons (CFCs) deplete the stratospheric ozone layer?

UV radiation breaks CFCs apart, releasing chlorine atoms that catalytically destroy ozone molecules CFCs absorb ozone directly and convert it to oxygen at ground level CFCs react with nitrogen oxides to form ozone-consuming acids CFCs increase stratospheric temperatures, causing thermal breakdown of ozone

Correct Answer:

UV radiation breaks CFCs apart, releasing chlorine atoms that catalytically destroy ozone molecules

Question 4

A coal-fired power plant is identified as a major contributor to acid deposition damaging forests and lakes downwind. Which pair of emitted gases is primarily responsible?

Carbon dioxide and methane Carbon monoxide and ammonia Sulphur dioxide and nitrogen oxides Hydrogen sulphide and ozone

Correct Answer:

Sulphur dioxide and nitrogen oxides

Question 5

A lake receiving run-off from intensive agriculture develops dense algal blooms followed by fish kills. Which sequence correctly describes this eutrophication process?

Pesticide accumulation poisons algae, decomposition releases toxins, fish are poisoned Nutrient (N and P) enrichment stimulates algal growth, algae die and decompose, microbial decomposition depletes dissolved oxygen Sediment run-off blocks sunlight, plants die, pH rises and kills fish Thermal pollution warms the water, oxygen solubility falls, algae proliferate in warm water

Correct Answer:

Nutrient (N and P) enrichment stimulates algal growth, algae die and decompose, microbial decomposition depletes dissolved oxygen
