FLASHCARD QUESTION

Front

Carbon dioxide

Back

GHG that comes from the combustion of FFs and clearing of land (as organic matter decomposes). Single most important GHG because of its high atmospheric concentration, relative to other GHGs.

2.

FLASHCARD QUESTION

Front

Sulfur dioxide (SO2)

Back

A corrosive gas that comes primarily from combustion of FFs. Resp. Irritant, damages plant tissue, converts to sulfuric acid and acid rain.

3.

FLASHCARD QUESTION

Front

Particulate matter

Back

Solid or liquid particles suspended in air. Sources = combustion of pretty much all matter, construction, forest fires, volcanoes, roads. Resp. irritant, makes asthma worse, blocks sunlight (decreasing photosynthesis), and decreases visibility by creating haze.
