Living Things for 200
This term refers to animals
with backbones.
Living Things for 200
What are vertebrates?
Living Things for 400
A major difference between plants and
animals is that plants make their own
____ and animals do not.
Living Things for 400
What is food?
Living Things for 600
This pigment causes a plant to appear
green and absorbs visible light
from the Sun to provide the
energy for photosynthesis.
Living Things for 600
What is chlorophyll?
Living Things for 800
A term for all plants that have no
tissues/vessels to transport water
and food (algae and moss are
examples of this type of plant).
Living Things for 800
What is a non-vascular plant?
Living Things for 1000
These organisms, such as mushrooms,
mold, and yeast, may be one- or
many-celled, they absorb their food
(decomposers) and reproduce by
spores or hyphae.
Living Things for 1000
What are fungi?
Energy for 200
This sedimentary rock is made from
decayed organic matter and is the most
abundant fossil fuel in the world.
Energy for 200
What is coal?
Energy for 400
These are the light colors visible to the
human eye that are in the
electromagnetic spectrum (energy).
Energy for 400
What are red, orange, yellow,
green, blue, indigo, and violet
(ROYGBIV)?
Energy for 600
Natural gas can be made by
tremendous heat and pressure deep
underground. These kinds of rocks are
formed by this same type of
heat and pressure.
Energy for 600
What are metamorphic rocks?
Energy for 800
This process uses the sun’s energy in
plants to make food from carbon
dioxide and water.
Energy for 800
What is photosynthesis?
Energy for 1000
This metal is found in rocks all over the
world and is a main fuel source used in
nuclear power plants.
Hint: It is mostly found as a mineral called uraninite.
Energy for 1000
What is uranium?
Earth’s Surface for 200
This type of energy can be harnessed
when it travels from the earth’s core
towards the surface.
.
Earth’s Surface for 200
What is geothermal?
Earth’s Surface for 400
Out of the four main layers of the Earth
(crust, mantle, inner core, and
outer core), all living things
reside in or upon this.
Earth’s Surface for 400
What is the crust?
Earth’s Surface for 600
The movement along three types of
plate tectonic boundaries (divergent,
convergent, and sliding) can cause
this natural disaster.
Earth’s Surface for 600
What are earthquakes?
Earth’s Surface for 800
The percentage of the Earth’s surface
covered by the oceans.
Earth’s Surface for 800
What is 70 percent?
Earth’s Surface for 1000
The movement of weathered rocks;
one way this occurs is when humans
change landscapes (such as removing
plants) and expose loose soil.
Earth’s Surface for 1000
What is erosion?
Recycling for 200
To collect used materials to make
into new products rather than
throwing them away.
Recycling for 200
What is recycling?
Recycling for 400
It is good to recycle batteries because they
contain heavy metals such as mercury, lead,
cadmium, and nickel. Mercury, lead,
cadmium and nickel are examples
of the more than 100 of these that make
up all matter.
Recycling for 400
What are elements?
Recycling for 600
Look at the materials in the table. For every ton of this material we recycle,
we prevent the most carbon dioxide (CO2) from being emitted.

Recycling for 800
Look at the table. We recover the most of this material (both in
weight and as a percentage) from our municipal solid waste (trash).

you need to collect information about this each year.

Water for 200
This compound is essential for
all life to exist.
Water for 200
What is water?
Water for 400
This process involves the breakdown
of rocks and objects made from rocks
(such as buildings, statues, etc.),
and ultimately delivers minerals
to the ocean.
Water for 400
What is weathering?
Water for 600
About 97.5 percent of the water on Earth is this
type of water; it is a complex mixture of gases
(including oxygen) and dissolved solids
(including usually around 3.5% sodium
chloride). Humans cannot survive
by drinking this type of water.
Water for 600
What is salt water or sea water?
Water for 800
This produces much of the Earth’s
oxygen and serves as the base of the
ocean’s ecosystem.
