6.1 – Introduction to the Atmosphere & 6.2 – Stratospheric Ozone by...

BEFORE YOU START... Save this document to your desktop with the name “6.3 & 6.4 – yourname” Upload it to the folder Ms. McCrindle shared with you Complete your progress in this uploaded folder, NOT the one you saved to yourselves. Ms. McCrindle needs access to monitor progress / assess the work.

TASK Instructions You are required to work through each of the slides, and give as much detail as possible. The best way to learn throughout this task will be: Use pictures. Use your own words! (research, but read and then rewrite) A sample assignment may or may not be posted on www.msmccrindle.weebly.com to help guide you. Do not copy off the posted completed assignment. You should aim to finish Task 1 by Thursday, March 8th.

6.3 – Photochemical Smog

Describe each of the following, including some examples As always, be sure to use your own words! Primary Pollutants – Secondary Pollutants – Define anthropogenic: Define photochemical reaction:

Primary and secondary pollutants

Tropospheric Ozone What is the global warming potential of ozone gas? (state as a relation to CO2) How is tropospheric ozone formed? Explain and include an image List 4 adverse effects of tropospheric ozone:

Particulate Why are particulates especially dangerous?

Photochemical smog formation – fill in the blank Click to highlight the desired box and start typing

Photochemical smog What are the most favorable conditions to create smog? (p289 AND 290) What time of day does smog reach a maximum concentration, and why? What is the biggest contributor to smog? What are: VOCs PANs

Thermal inversion Describe, using pictures, thermal inversion

Choose 2 examples of action from the table below and evaluate them on the next slide

Evaluation (Make an appraisal by weighing up the strengths and limitations of something) 1. 2.

6.4 Acid Deposition

Acidity What is acid deposition? Where does “acidity” fall on the pH scale? What pH value is neutral? What is the pH of acid rain?

Pollution & Acid Rain What pollutants lead to acid rain? How do they form? Provide several sources (if possible) for each of the following: Sulphur dioxide Nitrogen oxides

Acid rain formation Briefly describe how nitrogen oxides and sulfur dioxide produce acid rain Examine Figure 6.4.4. What happens to the acid after it falls as wet/dry deposition?

Effects of acid deposition List 3 effects on acid deposition on soil, plants, water, and/or coniferous forests:

Toxic effects of acid deposition – Summarize the following effects Aluminum ions effect on fish/aquatic organisms Lichens Nutrient removal from soil Buildings Peat bogs Human health

Pollution Management Strategies If acid deposition became a more pressing issue to Manitobans, which strategy for pollution reduction in figure 6.4.8 would you feel be the most effective, and why?

Reducing the effects of acid deposition List one criticism for each of the 4 methods listed on page 299 Liming lakes – Reducing emissions – Precombustion techniques – End of pipe measures –
