Ecology Ch 15 Test Review

A ratio that compares the amount of water vapor the air contains to the maximum amount the air could hold at that temperature

• air pressure

• relative humidity

• radiation

• convection

This can trap smog close to the surface when a layer of cool, dense air stays near the ground under a layer of warm air

• cold front

• air mass

• convection current

• temperature inversion

Pollutants removed or changed chemically before they leave factory smokestacks is done by

• catalytic converters

• CFC's

• scrubbers

• inversions

Substances such as smoke and carbon monoxide released into the air are called

• secondary pollutants

• fossil fuels

• emissions

• air masses

• troposphere

• mesosphere

• stratosphere

The ozone hole was located primarily above

• Alaska

• United States

• Antarctica

• Montreal Canada

Which of the following is a provision of the Clean Air Act?

• it sets aside funds for research into pollution control

• it limits the use of motor vehicles

• it lets industries sue people who break the rules

• it prevents states from developing pollution regulations

Which is NOT a primary air pollutant?

• particulate matter

• VOC's

• carbon monoxide

• sulfuric acid

Northern Lights can be seen in which layer of the atmosphere?

• stratosphere

• ozonosphere

• thermosphere

• mesosphere

The Montreal Protocol

• required vehicles with catalytic converters

• had a goal to reduce emission amounts that affect health

• lets people sue industries that break air pollution rules

• called for major cuts in CFC production and signed by many nations
