Atmospheric Gases and Their Sources

The video discusses atmospheric CO2 and particulates, covering natural sources like lightning, forest fires, and volcanic eruptions. It explains cellular respiration, VOCs, and the role of oceans in CO2 levels. The Keeling Curve is introduced, showing seasonal CO2 fluctuations. Various sources of particulate matter are identified, and an FRQ practice is provided to explore the impact of road construction on air quality.
