Explain the difference between ground-level ozone and stratospheric ozone, in terms of formation, harmful/beneficial effects, and the influence of human activities. (6 points) a. what is meant by nox? what is the source of the nitrogen in nox that results from combustion? list two natural sources of nox? (3 points) b. describe the mechanism of anthropogenic global warming. in your explanation, be sure to distinguish between the actions of solar ultra-violet (uv) radiation and infrared (ir) radiation. how does a higher concentration of greenhouse gases result in a warmer planet? (4 marks) c. d. calculate the carbon dioxide equivalents of the following three emissions of gases: 0.040 mg of ch4, 3.36 kg of n20, and 43.8 kg of sf6. rank them in terms of their global warming potential.
