Definition
Any hydrocarbon that may be used as energy.
Term
What are the 4 stages of the making of coal (Carbonization)
Definition
Peat, Lignite, Bitiminous coal, Coal
Term
Formation of Petroleoum and Natural Gas

Term
Tar Sands
Definition
Mixture of clay and sand combined with water and thick tar called bitumen.
Term
Oil Shale
Definition
rock that contains waxy mixture called hydrocarbon. not cost efficient
Term
Ore
Definition
rock that has useful metallic mineral that can be mined for a profit
Term
Igneous Process
Definition
large body of magma cools and heavy minerals crystallize first and settle at the bottom of the chamber
Term
Hydrothermal Solutions
Definition
Last stage of magma cooling leaves hot water. water seeps into cracks and moves away from hot rock. as water cools minerals ions are attracted to one another and deposit in cracks called veins.
Term
Placer Deposits
Definition
When natural sorting of erosion material occurs (Like panning for gold)
Term
Nonmetallic Minerall resources
Definition
needed for pyhysical and chemical properties. Used as building materials and Industrial materials.
Term
Solar Energy(Advantages and Disadvantages)
Definition
A:clean, free, non polluting.
D:Equipment is expensive(photovoltaic)
Term
photovoltic
Definition
panels used for solar energy
Term
Nuclear energy (A + D)
Definition
A:high energy output
D:High cost. hard to dispose of waste. danger of accident.

Comes from nuclear fission
Term
Wind Energy(A+D)
Definition
A:free energy, non polluting, lots of wind
D:Cost, and service, wind pollution, finding land without inhabitants
Term
Hydroelectric Power (A+D)
Definition
flowing water turns turbines to creat power
A:water is stored to be used anytime, not polluting air
D:dam has definate life span. Cost to dredge and environmental effect downstream
Term
Geothermal Energy (A+D)
Definition
using natural underground reserviors of hot steam and water
A:No environmental pollution
D:Steam will run out, have to keep drilling
Term
Tidal Power(A+D)
Definition
construct dam in a bay, allow water through high tide, when tide changes water flows through turbines.
A: non polluting
D: availability of water. only few tides a day
Term
What are the two types of water pollution?
Definition
Point and Non Point pollution
Term
what causes Global Warming?
Definition
caused by increase of co2
Term
Chlorofluorocarbons
Definition
breaks down ozone layer by joining with O2
Term
farming
Definition
irrigation makes land farmable but uses up groun water which increases salinity in soil
Term
Mines
Definition
Tears down vegetaion and increases soil erosion
Term
Clear Cutting
Definition
Cutting down trees for building material. destroys habitat. replanting forest decreases diversity (bad for forest)
Term
Disposal
Definition
landfills can contaminate ground water
Term
conservation
Definition
careful use of resources
Term
pollution prevention
Definition
stop pollution from getting in the environment
Term
Clean water act(1972)
Definition
protecting americas water
Term
Clean air act(1970)
Definition
restricted amount and type of pollution power plants and cars can release
Term
soil conservation
Definition
rotate crops
Term
selective cutting
Definition
only cutting some trees for logging and leaving the rest
Term
land
Definition
preventing solutions and managing land resources
Term
farming
