5 True/False Questions
thermal inversion → a departure from the normal temperature distribution in the atmosphere, in which a pocket of relavitevly cold air occurs near the ground, with warmer air above it.
photochemical smog → When coal or oil is burned, some portion is completly combusted, forming CO2
convective circulation → A circular current driven by temperature differences, in the air warm air rises into regiona of lower atmospheric pressure, where it expands and cools and then descends and becomes denser.
Lead → A highly toxic, radioactive, colorless gas that seeps up from the ground in areas with certin types of bedrock and can build up inside basements and homes with poor air circulation
Tropospheric ozone → the bottomost layer, blankets earths surface and provides us the air we need to live
