The layer of the atmosphereclosest to the Earth.
What is the Troposphere?
A yellow pollutant, found asan impurity in coal, that formsa gas when burned that reacts
with water to form acid rain.
What is sulfur?
These chemicals were the first to be banned for destroying
the stratospheric ozone.
What are chlorofluorocarbons?
These gases absorb infrared radiation andtrap heat on the Earth.
What are greenhouse gases?
The unreactive gas that makes up about 79%
by volume of the gases in the atmosphere.
What is nitrogen?
A vital substance inour stratosphere that
protects us from uv radiation butis a dangerous pollutant
at ground level.
What is ozone?
This treaty, signed by all UN countries in 1987, is an
agreement to ban the use of certain ozone damaging gases .
What is the Montreal Protocol?
The concentration of this gas in our atmosphere has been
increasing more rapidly since theindustrial age and is now
measured at about 390 ppmv.
What is carbon dioxide?
The tilt of the Earth on its axis.
What causes summer and winter (the seasons)?
A reddish brown gasthat causes smog and acid rain.
What is nitrogen dioxide?
Although we’ve stoppedproducing CFCs this
will take another 50-60 years.
How long will it take for the ozone layer to repair?
An effect of increased dissolved CO2 that damages coral reefs.
What is ocean acidification?
The method of heat transfer where matter absorbs pure energy carried by photons.
What is heat transfer by radiation?
This legislation resulted insignificant decreases inall major air pollutantsmonitored by the EPA.
What is The Clean Air Act?
These effects would beexpected in a world
where the ozone layer is severely depleted.
What are increased skin cancer and eye cataracts?
Carbon dioxide, methane,water, sulfur hexafluoride
What are some important greenhouse gases?
The reflectivity of a surface.
What is albedo?
This kind of air pollution is caused by emissions of nitrogen oxides
that react with ultraviolet radiationto form secondary pollutants.
What is photochemical smog?
These banned substances were once used in refrigerators and
air conditioners.
What are chlorofluorocarbons?
The leading international body for the assessment
of climate change.
What is the IPCC ?
