Quick-Fire Review: The Atmosphere and Air Pollution

Take a breath. The air you just pulled in has been drifting around this planet for billions of years, and in a city it arrives carrying whatever the last few kilometres pushed into it. This is Quick-Fire Review. Same format as always. A question, a moment to answer it yourself, then the answer and the reason.

0:00 / 9:23
This is a fast pass through the atmosphere and air-pollution material in Environmental Systems and Societies, with eleven questions, each one followed by the answer and the reasoning that earns the mark.

What this review covers

The air and its layers. Which layer holds the weather and why, why the temperature climbs as you go up through the stratosphere, and what an albedo of zero point two five does to the energy arriving at a square metre of ground.
How pollution builds. Why the smallest particles do the most damage, the sunlight chemistry that turns traffic fumes into photochemical smog, and why a city in a valley can sit under the same brown layer for a week.
Ozone, indoors and the response. How chlorofluorocarbons strip ozone out of the stratosphere from far below, why a cooking fire matters more than the street for much of the world, and what made the Montreal Protocol work.
Reading the numbers and cutting the source. A roadside-and-park nitrogen dioxide set to interpret, and the difference between a measure that removes pollution and one that only moves it.

How to use it

Answer each question before the host gives it away. The pause is there for exactly that. If you get one wrong, the reason that follows is the part worth repeating, because that is where the marks live.
The ones that catch people out are the layer that holds the weather, albedo as the share reflected rather than the share absorbed, and moving pollution against removing it. Each turns on a single distinction, so say the distinction out loud before you say the answer.
Replay the whole thing the night before, and once more on the way to the exam.
