Unit 5 - Agriculture
Name 1 strategy/method that was part of the green revolution
list 3 fossil fuels
coal, oil, natural gas
What law gave the EPA the power to regulate on 6 criteria air pollutants, including lead?
the clean air act
What is it called when a body of water becomes enriched with nutrients, like those from fertilizers or animal waste?
eutrophication or eutrophic
What chemicals caused stratospheric ozone depletion?
CFCs (chlorofluorocarbons)
Name 2 ways we harvest fish.
Aquaculture, wild caught (nets, lines, trawling, etc)
List 3 forms of renewable energy
solar, wind, geothermal, hydrogen, biomass
What pollutant is released from burning fossil fuels, and is a precursor to photochemical smog and acid rain.
nitrogen oxides
Thermal pollution from a power plant will have the greatest impact on the concentration of what chemical in a body of water?
Dissolved oxygen
Name a characteristic of an invasive species
r selected, wide ecological range
What is a CAFO?
Concentrated Animal Feed Operation. A place where many animals are raised for human consumption on a relatively small amount of land to increase efficiency.
what is the main fuel for nuclear reactors?
uranium (235)
name a radioactive indoor air pollutant
radon
DDT & PCBs are both carbon-based synthetic compounds that don't break down easily. They are examples of:
POPs (persistant organic pollutants)
Name 1 reason that global warming causes sea levels to rise
thermal expansion or LAND ice melting
How could a genetically modified crop lead to more herbicide use? What about herbicide resistance?
If the modification makes the plant resistant to herbicide, more herbicides can be used to kill weeds that would compete with the crop. Eventually weeds that are resistant survive, and then a larger percent of the population has the resistant trait.
Name the 3 types of coal from least to most pure
lignite, bituminous, anthracite
What pollution control device is located on cars that reduces the number of harmful pollutants in a car's exhaust.
catalytic converter
Pick two diseases to describe: dysentery, malaria, mesothelioma, west nile, cholera
Dysentery — severe diarrhea with blood and dehydration; caused by contaminated food or water containing bacteria or parasites, Malaria — fever-causing disease spread by mosquitoes; caused by Plasmodium parasites transmitted through mosquito bites, Mesothelioma — rare cancer affecting organ linings; caused mainly by asbestos exposure; West Nile virus — viral infection spread by mosquitoes; caused by the West Nile virus transmitted from infected birds through mosquitoes; Cholera — severe dehydration from watery diarrhea; caused by contaminated water containing Vibrio cholerae bacteria
Name 2 greenhouse gases with a GWP greater than 1, and name the greenhouse gas with a GWP of 1.
Greater = methane, CFCs, N2O, HFCs
1 = CO2
Describe how soil salinization occurs
Water naturally has small amounts of minerals, like salt, dissolved in it. Repeated watering leaves that salt in the soil as the water gets absorbed or evaporates.
Describe the steps to turn coal into electricity
burn the coal, use the heat to boil water into steam, use the steam to turn a turbine attached to a generator
Describe a thermal inversion
A cool air mass gets trapped under a warmer air mass, trapping pollutants with it.
Describe primary, secondary and tertiary wastewater treatment.
primary - physical removal of large solid
secondary - biological removal of organic solids
tertiary - chemical treatment - disinfection
What does HIPPCO stand for?
Habitat destruction, Invasive species, Population, Pollution, Climate Change, Over exploitation
