PubH 6011 Midterm Study Guide Latest Update Exam | Questions and
Verified Answers | 100% Correct | Grade A +
Solar energy - ANSWER the primary power source that creates
fossil fuels→ drives life on earth
life cycle - ANSWER solar energy-->primary producers
photosynthesize, herbivores consume primary producers-->
carnivores, secondary carnivores→ detritivores consume
decaying matter
petroleum - ANSWER fossil fuel we use the most - 36%,
oil sandwich - ANSWER layer of carbon/sand/silt/plankton
biomass on top and bottom
Canadian Tar Sands - ANSWER oily sand is scooped into trucks
and boiled to separate oil
Sterilizes soil - makes forest regrowth difficult
Keystone Pipeline and Koch Brothers

Hydraulic Fracturing: - ANSWER horizontal angled drilling for
natural gas and oil
fractures rock, and fractures are filled w/ sand and the fluid to
prop the fractures open when the pressure is relieved
- deisel exhaust air pollution, chemicals in treatment,
dust/particulate matter, radioactive flowback water
Electricity - ANSWER still dominated by fossil fuels, but this is
beginning to change
Coal used to be cheapest, but now is the most expensive form
of electricity generation
Natural gas has become cheaper due to hydraulic fracturing
electricity is made by water - ANSWER thermoelectric plants:
boiling water turns into steam→ explosion runs through a
turbine, blades rotate a shaft that has a barrel with copper
wires and magnets
Coal - ANSWER most abundant form of fossil fuel
fading due to becoming expensive and increased use of natural
gas

Black Lung Disease: - ANSWER on the rise in coal miners
lungs get overburdened with coal dust
Coal dust starts to deteriorate the gas exchange region of the
lungs
reduces lung capacity and shortens life
weak regulations and enforcement are partly to blame in the
spike among miners
green jobs are safer
hydroelectric power - ANSWER 3% Shrinking due to an increase
in droughts
Many large rivers have already been dammed
ecological footprint, can disrupt a natural water body
combination of higher head and lower flow→ more water
pressure, more electricity
over time, these fill with silt, and become dangerous as they
age
geothermal - ANSWER 0.2% 2 types
