5 True/False questions
low-input high-diversity biofuels → mixed polycultures of perennial native species with a lot of biomass
low-level wastes → the upper surface of underground water; the upper boundary of the zone of saturation
oligotrophic → a plastic made from cellulose (or a derivative of cellulose)
aerosol → Solid, waxy mixture of hydrocarbons found in oil shale rock. Heating the rock to high temperatures causes the kerogen to vaporize. The vapor is condensed, purified, and then sent to a refinery to produce gasoline, heating oil, and other products. See also oil shale, shale oil.
sinkhole → when the roof of an underground channel or cavern collapses, creating a large surface crater
