Air Quality And Climate
Muhtasari
The air looks empty, but it is a carefully balanced mixture, mostly nitrogen and oxygen with a little carbon dioxide and the noble gases. Burn fuels, run engines and farm animals, and that balance shifts: pollutants build up, the air over cities turns hazy, and the planet slowly warms.
In this lesson you will learn the composition of clean air, the source and harmful effect of each major air pollutant, and how greenhouse gases such as carbon dioxide and methane trap heat to cause global warming and climate change. You will be able to match each pollutant to where it comes from and the damage it does.
Malengo
- [Core] State the composition of clean, dry air as approximately 78% nitrogen, N₂, 21% oxygen, O₂, and the remainder as a mixture of noble gases and carbon dioxide, CO₂
- [Core] State the source of each of these air pollutants, limited to: (a) carbon dioxide from the complete combustion of carbon-containing fuels (b) carbon monoxide and particulates from the incomplete combustion of carbon- containing fuels (c) methane from the decomposition of vegetation and waste gases from digestion in animals (d) oxides of nitrogen from car engines (e) sulfur dioxide from the combustion of fossil fuels which contain sulfur compounds
