What is 78% of
the atmosphere?
Be specific for the
points
Nitrogen gas N2
Not just Nitrogen
Nitrogen in plants
combines with this
when burned.
Oxygen
What is the
number one
method for getting
nitrogen into
plants?
Nitrogen fixation
by bacteria on
legumes’ root
nodules.
Name the 3 ways
that nitrogen
becomes a nitrogen
containing
compound.
Bacteria on legumes,
lightning (weather),
and commercial
fertilizer production.
Name two ways
that humans affect
the nitrogen cycle.
Fossil fuel burning,
waste and Sewage
in water, fertilizer,
cutting
plants/trees, etc.
How do plants get
CO2 to be usable?
Photosynthesis
How is carbon in
your body released
back into the
atmosphere?
Decomposition/
Bacteria or
respiration.
Where is the largest
carbon sink? Be
specific!
Bottom of
the ocean in
sediments
and rocks.
Increasing carbon
in the atmosphere
is believed to do
this…
Warm
temperatures/
global warming
What is the number
one way we increase
carbon in the
atmosphere?
Burning fossil fuels.
What does increased
driving of cars going to do
to our global temperatures?
Increase the heat.
True/False
Increasing carbon
dioxide is bad for
all life.
False. Plants love
it!
This is how we get
CO2 removed from
the air.
Trees!
Besides burning
fossil fuels, this
increases CO2 in
the atmosphere.
Cement production,
volcanoes, ocean,
deforestation,
breathing,
decomposition.
This is the #1
greenhouse gas.
Water Vapor
Acid rain is caused
by this human
activity.
Burning fossil
fuels.
Name three effects
of acid rain.
Kills trees, fish,
acidifies water,
ruins sculptures
and buildings.
Ozone is found
mostly here.
Stratosphere
Without an ozone
layer, this would
increase on the
surface.
Ultraviolet rays
This is the
anthropogenic
chemical that
destroys ozone.
Chlorofuorocarbons
or CFCs
Most of the energy
we use on Earth
comes from…?
Mr. Sun, Sun, Mr.
Golden Sun
Light energy from
the sun is converted
to this when it hits
objects like your
head.
Heat energy
The reflectivity of
an object (how
much light it
bounces) is
called…
Albedo
Why is heat a form
of energy?
It can do work.
How is sunlight
mainly stored on
Earth?
In plants through
photosynthesis.
Nitrates and
Sulfates can cause
this to be seen in
the air.
Smog.
This is the main
reason CO2 has
spiked since 1850.
Industrial
Revolution
What role should
scientists play in
making public
policy and law?
Provide data,
nothing more.
Tess designed an experiment to measure
how color affects the absorption of solar
energy. She covered one Styrofoam cup
with a black, nylon sock and another
Styrofoam cup with a white, cotton sock.
She left a third cup uncovered. She filled
all three cups with 100 ml of room
temperature water and set them in the
sun. After 60 minutes, she measured the
temperature of each of the cups.
What’s wrong?
2 independent
variables
Why is the street
warmer than the
sidewalk next to it?
Lower albedo of
asphalt compared
to concrete.

first name?
