Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

surface fires
20. The finest soil - made up of particles that are less than 0.002 mm in diameter.
assimilation
gray smog (industrial smog)

natural resources
anthracite
law of conservation of matter
22. A symbiotic relationship in which one member is helped by the association and the other is harmed.
parasitism
chemical weathering
nuclear fusion
keystone species
23. Using strategies to reduce the amount of risk (the degree of likelihood that a person will become ill upon exposure to a toxin or pathogen).
Coriolis effect
risk management
solid waste
second growth forests
24. The phenomenon whereby the Earth's atmosphere traps solar radiation - caused by the presence in the atmosphere of gases such as carbon dioxide - water vapor - and methane that allow incoming sunlight to pass through - but absorb heat radiated back fr
