APES TEST REVIEW Unit 2 (Unit 9)

Ozone in the stratosphere absorbs

• Most of the CFC's in the atmosphere

• heat radiated back from earth

• Most of the UV-B and UV-C radiation

• Most of the CO2

NGSS.HS-PS4-3

Without the ozone layer, what might happen to humans?

• freeze because of the lack of greenhouse gases

• die because of pollutants in air

• skin cancer and cataracts

• die from lack of oxygen

Good up high, bad near by refers to what?

• Tropospheric Ozone caused by pollutants can damage lungs

• O3 in the Stratosphere is bad, but O2 nearby is good

• Tropospheric Oxygen caused by plants can damage lungs

• CO2 in the statosphere is good, but is a pollutant in the troposphere

O2 in the stratosphere needs this item to create O3

• carbon dioxide

• chlorine

• flourine

• UV rays

Natural ozone depletion happens with the help of

• hydrofluorocarbons

• chlorofluorocarbons

• Cumulus clouds over New York

• polar stratospheric clouds

Where is the hole in the ozone layer?

• Over parts of Australia

• Over the South pole - Antarctica

• Over the North pole - over frozen water

• Over most of Alaska

What anthropogenic mixture enlarged the hole in the ozone layer?

• HCFC's

• CH3's

• HFC's

• CFC's

CFC's were replaced with HFC's that do not deplete the ozone layer, so what's the problem?

• HFC's still deplete the ozone layer

• HFC's are strong greenhouse gases

• HFC's mix with sulfur to create methane

• HFC's sink to the bottom of the ocean

The heat from the greenhouse gases

• comes straight from UV rays

• is trapped in the gases as it is reflected off the earth

• are heated as they move through clouds over antarctica

• is reflected from the moon
