Potentially toxic gases emitted by certain organic solids and liquids and can evaporate readily from solid or liquid form.
New cards
43
Finite resources
Natural resources that can be worn out (all used up) and cannot be replaced. (i.e. coal)
New cards
44
Depletion time
the time it takes to use up a certain proportion of the reserves of a mineral at a given rate of use
New cards
45
Fractional distillation
A process of petroleum refining, by which a chemical mixture such as petroleum is separated into its components depending on the different boiling points of components.
New cards
46
shale oil
Slow-flowing, dark brown, heavy oil obtained when kerogen in oil shale is vaporized at high temperatures and then condensed. Shale oil can be refined to yield gasoline, heating oil, and other petroleum products.
