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