Document Summary
Questions will be drawn equally from each chapter. In part b you need to answer 3 (three) of 5 (five) essay questions. Acid deposition is the process of depositing acids as solid or liquid forms on the earth"s surface that can be found in rain, snow, fog, etc. Most commonly, acid deposition is produced from the second pollutants that form from oxidation of nitrogen oxides or sulfur dioxide gases released into the atmosphere. These pollutants can fall to the ground simply as dry deposition, or as wet deposition of which is formed when nox and so2 are converted to nitric acid and sulfuric acid through oxidation and dissolution. It is dangerous because it influences the aquatic ecosystems by lowering the ph level. Also, it damages the vegetation and reduces the available nutrients in soil for plant growth because plants cannot grow below a ph 6. 0. Stratospheric ozone holes are the seasonal thinning of the ozone layer primarily at the.
