Greenhouse Gases and Ozone Depletion Review

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

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

O2 in the stratosphere needs this item to create O3

• carbon dioxide

• chlorine

• flourine

• UV rays

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

What is the primary cause of ozone layer depletion?

• Greenhouse gases

• Chlorofluorocarbons (CFCs)

• Carbon monoxide

• Sulfur dioxide

How do greenhouse gases contribute to global warming?

• By reflecting sunlight away from Earth

• By absorbing and re-emitting infrared radiation

• By increasing the Earth's albedo

• By releasing oxygen into the atmosphere
