Exam 3

Which of the following are consequences of burning coal for energy?

-increased levels of CO2 -increased heavy metals in air -acidified rain

T/F - Energy conservation can reduce energy demands but will require a change in the standard of living.

False

One of the most obvious environmental impacts of hydroelectric dams is:

flooding of vast areas of land.

What is the proposed alternative to drilling for oil in ANWR?

increased energy conservation

T/F- Inhaled small particulate material, less than 2.5 micrometers in diameter, poses a greater risk to human health than larger, coarse particles do.

True

Resource

naturally occurring substance of use to humans that can potentially be extracted

criteria pollutants

pollutants contributing the largest volume of air quality degradation and also are considered the most serious threat of all air pollutants to human health and welfare.

secondary pollutants

pollutants converted to a hazardous form after they enter the air or are formed by chemical reactions as components of the air mix and interact.

primary pollutants

pollutants released directly from the source into the air in a harmful form.

scrubbers, precipitators, and filters:

reduce particulate pollution.

What is NOT a conclusion of the IPCC?

there is a direct correlation btwn temp decrease and the amount of greenhouse gases.

What is hydraulic fracturing used for?

to extract oil and natural gas from shale

What applies to the Deepwater Horizon oil rig?

- 10,000 tons of oil released before it was sealed. -this is the largest oil spill on record -it caught fire and sank in 2010

Which of the following statements about the GE are true?

- allows life to exist on earth -water vapor is a major contributor -increases in heat are caused by infrared radiation emitted from the earth

Match air pollutants to their effect on human health:

-carbon monoxide - inhibits respiration in animals -nitrogen oxides - increase eutrophication of surface water -particulate matter - damages lung tissues and causes cancer -sulfur dioxide - major component of acid rain

The Clean Air Act:

-set national ambient air quality standards for six pollutants. - principal framework for efforts to protect air quality in U.S.

Which of the following statements are true about the troposphere?

-where majority of the weather occurs -we find majority of the air pollutants here

What percentage of the world's commercial energy is furnished by fossil fuels?

80%

Match each of the main air pollutants to its main causative agent.

Carbon monoxide - incomplete burning of fossil fuels sulfur dioxide - mining and manufacturing processes particulate matter - asbestos and cigarette

T/F - renewable sources of energy could produce enough energy to eliminate the need for fossil fuels in the near future

True

the amount of lead released into the atmosphere:

has declined since the introduction of lead free gas.

Why is carbon monoxide dangerous?

it binds with hemoglobin, reducing the blood's oxygen carry-capacity.

reserve

known deposits from which materials can be extracted profitably with existing technology under prevailing economic conditions.

The second most abundant greenhouse gas is:

methane

what is the process whereby a platform with many wells is secured to the ocean floor?

offshore drilling

Acid mine drainage occurs when:

oxygen, water, and bacteria cause sulfur to form sulfuric acid

atmospheric warming due to the presence of greenhouse gases is called:

the greenhouse effect.

The main activity of the IPCC is:

to provide regular intervals of assessments of climate change knowledge.
