Which rapid decline in air quality will result when a pyroclastic flow enters a densely forested ravine?

💡 Explanation

Pyroclastic flows instantly consume vegetation, resulting in particulate matter displacing breathable air, because intense burning and ash occur; therefore the limited oxygen causes asphyxiation rather than photochemical smog needing hours or acid rain derived after the event.
