Term
Extrusive
Definition
ingneous rock that cools quickly and has small crystals
Term
El Nino
Definition
a periodic change in coeanic and atmospheric conditions causing unusually warm surface water
Term
intrusive
Definition
igneous rock that cools and has large crystals.
Term
Coriolis effect
Definition
the way the Earth's rotation affects wind and ocean currents
Term
lava
Definition
the magma that reaches the surface of the earth
Term
sea mount
Definition
an undersea volcanic mountain found on the deep ocean basin
Term
upwelling
Definition
the movement of cold, deep ocean water to the ocean's surface
Term
deep ocean current
Definition
a stream of water that flows deep beneath the ocean's surface
Term
metamorphic
Definition
This type of rock is formed as a result of heat and pressure.
Term
igneous
Definition
This type of rock is formed as a result of cooling lava.
Term
sedimentary
Definition
This type of rock is formed when wind and water break down other rock types.
Term
igneous
Definition
Examples of this rock include granite, basalt, and obsidian.
Term
sedimentary
Definition
Examples of this rock are sandstone, shale, and limestone.
Term
metamorphic
Definition
Examples of this type of rock include marble, gneiss, and slate.
Term
subduction
Definition
When a dense ocean plate meets a less dense continental plate at a convergent boundary, the denser plate is forced down into the earth's hot mantle.
Term
Mid-Atlantic range
Definition
An ocean floor feature that has been formed when two plates diverge leaving a gap. The opening fills with lava and hardens to form igneous rock.
Term
polarity
Definition
What word describes the reason why the alternating stripes in the ocean floor point in opposite directions?
Term
Plate Tectonics Theory
Definition
The current theory that describes how Earth's crust is broken into plates that float on the earth's mantle layer.
Term
Drought, intense storms, increased rainfall
Definition
Examples of weather conditions caused by El Nino.
Term
Magnetite
Definition
This is a rock containing molecules that always orient themselves toward magnetic north.
Term
Temperature and salinity
Definition
These are two important factors that affect the density of ocean currents.
Term
upwelling
Definition
When ________ does not occur, nutrients from the ocean's bottom do not surface and the fish suffer.
Term
volcanoes, earthquakes, tsunamis
Definition
The movement of the Earth's plates can cause these natural disasters.
Term
If animal or plant remains were trapped inside other rock types, they would be heated beyond recognitioin or put under too much pressure to be preserved.
Definition
Why are fossils only found in sedimentary rocks and not in the other two rock types?
Term
Continental Drift Theory
Definition
This theory states that they continents used to be connected and that they eventually drifted apart.
Term
Seafloor Spreading Theory
Definition
This theory states that they ocean floor is expanding in some places because magma is coming up through openings at divergent boundaries and hardening into igneous rock.
Term
What process do some places in the world use to obtain freshwater?
Definition
Desalination
Term
Trees and freshwater are what kind of resources?
Definition
Renewable
Term
These are good conductors of heat and energy.
Definition
Metals
Term
A great way to reuse and recycle plants and food scraps is by making. . .
Definition
Compost
Term
What are three fossil fuels?
Definition
natural gas, petroleum, coal
Term
True/False: When a student uses an insulated bottle for his drink every day, he is REDUCING.
Definition
False/ He is REUSING.
Term
True/False: MINERALS are extracted from the ground and refined into valuable metals.
Definition
False: ORES are extracted and made into metals.
Term
True/False: Materials found in nature that are useful to humans are NATURAL RESOURCES.
Definition
True
Term

Animals are a ________ resource?
Definition
Renewable
Term
Wood is a _______ resource?
Definition
Renewable

Salt is a _______ resource?
Definition
Nonrenewable
Term
Paper is a _______ resource?
Definition
Renewable
Term
Iron is a _____ resource?
Definition
Nonrenewable
Term
Air is a _____ resource?
Definition
Renewable
Term
Diamond is a ______ resource?
Definition
Nonrenewable
Term
Wind is a _____ resource?
Definition
Renewable
Term
Aluminum is a _____ resource?
Definition
Nonrenewable
Term
List five physical properties that can be used to identify minerals.
Definition
Hardness, luster, streak, color, and cleavage
Term
Explain how a pizza box solar oven works.
Definition
A pizza box solar oven captures sunlight and converts it to heat energy. Aluminum foil reflects the light into the box. The black construction paper absorbs the heat. The plastic wrap and newspaper insulate the oven to keep the heat inside.
Term
You find a paper clip in the hallway at school. You should:
Definition
Reuse it.
Term
The school year has ended, and you do not need your science notebook anymore. You should:
Definition
Recycle it.
Term
After eating dinner at a restaurant, you use one of their mint toothpicks. You should:
Definition
Throw it away.
Term
Your local grocer is double bagging your groceries. You should:
Definition
Reduce the waste, reuse it, or recycle it.
Term
Coal is what kind of rock?
Definition
Sedimentary
Term
What kind of energy is produced from heat trapped within the earth?
Definition
Geothermal energy
Term
Methane, propane, and butane are all what?
Definition
Hydrocarbons
Term
If you need to throw away paint, pesticides, and automotive fluids, what should you do with them?
Definition
I should take them to special recycling or disposal centers because they can be hazardous to the environment.
Term
Why should you conserve and protect your natural resources?
Definition
God gave us all our natural resources for our use. They are important for life. Some can not be renewed. Those that are renewable may be used up faster than they can be replaced. Conserving and protecting will help future generations have these resources available.
