QUESTIONS AND ANSWERS FULL REVIEW
●● Tragedy of the Commons
Answer: many common property and open access renewable resources
have been degraded due to lack of management
●● Ecological Footprint
Answer: the amount of biological productive land and water needed to
supply the people n a particular country or area with resources and to
absorb and recycle the wastes and pollution produced by such resource
use
●● Nonpoint Source Pollution
Answer: dispersed and often difficult to identify
Ex: pesticides blown from the land into the air and the runoff of
fertilizers and pesticides from farmlands, lawns, gardens, and golf
coerces into streams and lakes
●● Point Source Pollution
Answer: single, identifiable sources
Ex: the smokestack of a coal-burning power or industrial plant, the
drainpipe of a factory, and the exhaust pipe of an automobile
,●● Positive Feedback Loop
Answer: Causes a system to change further in the same direction.
●● Negative Feedback Loop
Answer: A feedback loop that causes a system to change in the opposite
direction from which it is moving; stabilizing
●● green roof (living roof)
Answer: plants grown on top of buildings, provides insulation, absorbs
rainfall to reduce runoff, absorbs CO2, and can provide food; aka living
roof
●● albedo
Answer: ability of earth's surface to reflect heat
●● major greenhouse gases
Answer: water vapor, carbon dioxide, nitrous oxide, methane,
clorofluorocarbons, tropospheric ozone
●● methane
Answer: chemical formula is CH4, 20x as potent as CO2
,●● thermal expansion
Answer: the expansion of matter when it is heated; main cause of sea
level rise
●● ocean acidification
Answer: decreasing pH of ocean waters due to absorption of excess
atmospheric CO2 from the burning of fossil fuels
●● ice core sampling
Answer: A long cylindrical sample removed from an ice sheet or a high
mountain glacier. Since the ice forms from incremental buildup, past
climate and air quality information is preserved in the ice layers.
●● Hadley Cell
Answer: a system of vertical and horizontal air circulation
predominating in tropical and subtropical regions and creating major
weather patterns.
●● ocean conveyor belt
Answer: Interconnected flow of currents that redistribute heat
throughout the Earth; based on temperature and salinity of the water
●● Ecosystem
, Answer: A community of different species interacting with one another
with their nonliving environment of matter and energy
●● Biomes
Answer: Large region such as forests, deserts, and grasslands with
distinct climate and certain species adapted to them
●● Abiotic
Answer: Nonliving things
●● Biotic
Answer: Living things
●● Range of Tolerance
Answer: a set of conditions in which an organism is best adapted to
survive
●● Autotrophs
Answer: Make their own food
●● Limiting factor
Answer: Too much or too little of any abiotic factors can limit or prevent
growth of a population
