What are the main layers of Earth's atmosphere in order from the surface?1 / 10

Troposphere (0–12 km): contains 75% of atmospheric mass and all weather; temperature decreases with altitude (~6.5 °C/km lapse rate). Stratosphere (12–50 km): temperature increases with altitude due to ozone absorption of UV; location of the ozone layer. Mesosphere (50–80 km): temperature decreases again; meteors burn up here. Thermosphere (80–600+ km): temperature rises dramatically; very low density; aurora borealis/australis form here. Exosphere: outermost fringe, merging with interplanetary space.

State the Beer–Lambert law for monochromatic radiation passing through an absorbing medium.1 / 8

Radiation intensity I decays exponentially with optical depth τ traversed. I₀ is the incident intensity; τ integrates the absorber's extinction along the path.

What is potential evapotranspiration (PET)?1 / 9

The amount of water that would evaporate from soil and transpire from plants in a given location if water supply were unlimited — essentially the atmosphere's 'demand' for water, driven mainly by temperature, sunlight, humidity, and wind.

What is the single largest global driver of deforestation today?1 / 8

Agricultural expansion is the largest driver worldwide — clearing forest for cattle ranching, and for crops like soy and oil palm, accounts for a bigger share of global forest loss than logging or infrastructure combined.

What is a wet scrubber, and how does a limestone slurry scrubber remove SO2 from flue gas?1 / 8

A wet scrubber contacts flue gas with a liquid (often a limestone/water slurry) to dissolve or react out acid gases. For SO2: SO2 gas dissolves into the slurry and reacts with the limestone (CaCO3), ultimately forming solid calcium sulfate (gypsum, CaSO4) — this flue-gas desulfurization (FGD) reaction removes over 90% of SO2 in modern coal plants, and the gypsum byproduct is often sold commercially (e.g. to wallboard manufacturers).

How does a modern sanitary landfill differ from an open dump?1 / 8

A sanitary landfill engineers containment: a composite liner (compacted clay plus an HDPE geomembrane) beneath the waste stops leachate from reaching groundwater, a leachate collection system pipes percolate to treatment, daily soil (or alternative) cover controls odor/vectors/blowing litter, and landfill gas is actively collected. An open dump has none of these controls — waste is simply deposited on the ground with no liner, no leachate management, and no gas capture.
