• A change to the atmosphere that has harmful
effects.
– Substances that cause pollution are called
pollutants. (ash, or gases, such as chlorine.)
– Air pollution can affect the health of humans and
other living things.
– Pollution can even impact the climate of the
whole planet.
• A change to the a_________ that has harmful
e______.
– Substances that cause pollution are called
pollutants. (ash, or gases, such as chlorine.)
– Air pollution can affect the health of humans and
other living things.
– Pollution can even impact the climate of the
whole planet.
• Solid particles and gases that are released into
the air.
– Sources: motor vehicles such as cars, trucks, and
airplanes.
– Release gases such as carbon monoxide, an
invisible toxic (poison) gas.
• Solid p_____ and g____ that are released into
the a__.
– Sources: motor vehicles such as cars, trucks, and
airplanes.
– Release gases such as carbon monoxide, an
invisible toxic (poison) gas.
• A toxic (poison) form of oxygen.
– Ozone in the ozone layer is helpful because it
blocks ultraviolet rays from the sun.
– Ozone in the lower atmosphere is not good
because it is toxic to humans.
• A t___ (poison) form of o_____.
– Ozone in the ozone layer is helpful because it
blocks ultraviolet rays from the sun.
– Ozone in the lower atmosphere is not good
because it is toxic to humans.
• The trapping of heat by certain gases in the
atmosphere.
– In the atmosphere, water vapor, carbon dioxide,
and certain other gases act like windows. These
gases allow sunlight to reach Earth’s surface, but
they prevent the heat from escaping back into
space. The trapping of heat near Earth’s surface is
called the greenhouse effect. Without the
greenhouse effect, Earth would be much colder –
about 33°C colder on average.
• The t______ of heat by certain gases in the

• The theory that increasing carbon dioxide in
the atmosphere will raise Earth’s average
temperature.
– Scientists estimate temp could raise 3 to 8 Celsius
degrees over the next century.
– Though this seems small, this could cause
Antarctic ice caps to melt  rising sea levels,
changing climate patterns.
• The theory that i________ carbon dioxide in
the a_________ will raise Earth’s average
t_________.
– Scientists estimate temp could raise 3 to 8 Celsius
degrees over the next century.
– Though this seems small, this could cause
Antarctic ice caps to melt  rising sea levels,
changing climate patterns.
• The total amount of CO2 you create.
– A big carbon footprint is bad for the planet.
– When you use fossil fuels, like heating oil to keep
your house warm or gasoline for your family car,
these things create carbon dioxide, also called
CO2. Carbon dioxide is called a greenhouse gas.
Many scientists believe that greenhouse gases are
making the earth too warm (global warming).
• The total a_____ of CO2 you c_____.
– A big carbon footprint is bad for the planet.
– When you use fossil fuels, like heating oil to keep
your house warm or gasoline for your family car,
these things create carbon dioxide, also called
CO2. Carbon dioxide is called a greenhouse gas.

• All of the living (biotic), and nonliving (abiotic)
things that interact in a particular area.
– Biotic – animals, fungus, worms, plants, etc.
– Abiotic – water, sunlight, oxygen, temperature,
soil
• All of the l____ (biotic), and n______ (abiotic)
things that i_______ in a particular area.
– Biotic – animals, fungus, worms, plants, etc.
– Abiotic – water, sunlight, oxygen, temperature,
soil
• Resources that are replaced in a relatively
short time.
– Sunlight, wind, trees, etc.
– Possible to use up renewable resources, for
example if people cut down trees faster than they
can grow back then they will be used up.
• Resources that are r_______ in a relatively
s____ time.
– Sunlight, wind, trees, etc.
– Possible to use up renewable resources, for
example if people cut down trees faster than they
can grow back then they will be used up.
• Natural resources that are not replaced as
they are used.
– Coal and oil exist in a limited supply so they are
non-renewable.
– The time necessary to make these resources is
much too long to be considered renewable
• Natural r_______ that are not r_______ as
they are used.
– Coal and oil exist in a limited supply so they are
non-renewable.
– The time necessary to make these resources is
much too long to be considered renewable
