-particulates
-VOCs (volatile organic compounds)

Question 12

Fracking risks/disadvantages

Answer 12

-Groundwater/aquifer pollution
-releases methane
-earthquakes
-Fossil fuels are a finite resource
-fossil fuel collection damages the environment
-combust creating an acidic environment
-may contribute to public health issues
-Fossil fuels can be dangerous to collect

Question 13

the release of a large amount of heat in nuclear power plants to boil water to produce steam

Answer 13

Nuclear Fission

Question 14

Problems associated with Nuclear Power

Answer 14

(Main ones:) waste & thermal pollution
-Nuclear power is nonrenewable
-Decreased levels of dissolved O2 (DO)
-waste is expensive to dispose of
-hazardous solid waste

Question 15

Nuclear Disasters

Answer 15

Three Mile Island, Chernobyl, and Fukushima

Question 16

Best way to store radioactive waste

Answer 16

underground away from populated areas

Question 17

Solar energy systems have low environmental impact and produce clean energy, but

Answer 17

are expensive, their use is limited by sunlight availability, manufacture releases toxic chemicals into the air & large solar energy farms may negatively impact desert ecosystems

Question 18

Active solar energy

Answer 18

the use of solar energy to heat a liquid through mechanical and electric equipment to collect and store the energy captured from the sun

Question 19

Passive Solar Energy

Answer 19

-absorb heat directly from the sun
-no mechanical or electric equipment used
-energy cannot be collected or stored

Question 20

Hydroelectric power benefits and disadvantages

Answer 20

does not generate air pollution but

-expensive and can alter habitats
(EX: nutrient-rich silt deposited downstream is now deposited behind the dam)
-Equipment & suspension corrosion caused by ocean water
-Opposed by trawler fishermen

Question 21

Best way to diminish fish mortality at hydroelectric power plants?

Answer 21

Fish ladders

Question 22

the major source of energy for domestic use in developing countries, production is cheaper than fossil fuel extraction, making it more readily available for use.

Answer 22

Biomass

Question 23

cleanest of the fossil fuels, mostly methane

Answer 23

Natural gas

Question 24

Advantage of using natural gas

Answer 24

is that natural gas is cleaner (than oil) because it burns more completely

Question 25

Disadvantages of Geothermal energy production

Answer 25

-high upfront cost
-electricity is needed to operate pumps
-noise
-release of corrosive chemicals

Question 26

Answer 26

along plate boundaries ranging from short distances below, to miles below the surface

Question 27

Negative Effect of Wind Farms

Answer 27

migratory birds and bats are killed

Question 28

Offshore winds farms are ________ productive than those onshore

Answer 28

more

Question 29
