things (22 cards)
Natural Resource
materials or substances such as minerals, forests, water, and fertile land that occur in nature and can be used for economic gain.
Renewable Resource
a substance of economic value that can be replaced or replenished in the same or less amount of time as it takes to draw the supply down.
Nonrenewable Resource
a resource of economic value that cannot be readily replaced by natural means on a level equal to its consumption.
Fossil Fuel
a natural fuel such as coal or gas, formed in the geological past from the remains of living organisms.
Nuclear Fission
a nuclear reaction in which a heavy nucleus splits spontaneously or on impact with another particle, with the release of energy.
Nuclear Fusion
n nuclear physics, nuclear fusion is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles.
Hydrogen Fuel Cell Vehicle
fuel cell vehicle or fuel cell electric vehicle is a type of electric vehicle which uses a fuel cell, instead of a battery, or in combination with a battery or supercapacitor, to power its on-board electric motor.
Solar Energy
Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture, molten salt power plants and artificial photosynthesis.
Wind Energy
Wind power is the use of air flow through wind turbines to provide the mechanical power to turn electric generators.
Hydroelectric energy
Hydroelectricity is electricity produced from hydropower.
Biomass
the total mass of organisms in a given area or volume.
Gasohol
a mixture of gasoline and ethyl alcohol used as fuel in internal combustion engines.
Geothermal Energy
Geothermal energy is thermal energy generated and stored in the Earth.
Petroleum
a liquid mixture of hydrocarbons that is present in certain rock strata and can be extracted and refined to produce fuels including gasoline, kerosene, and diesel oil; oil.
Natural Gas
Natural gas is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but commonly including varying amounts of other higher alkanes, and sometimes a small percentage of carbon dioxide, nitrogen, hydrogen sulfide, or helium.
Coal
a fossil fuel that forms when dead plant matter is converted into peat, which in turn is converted into lignite, then sub-bituminous coal, after that bituminous coal, and lastly anthracite.
Propane
Propane is a three-carbon alkane with the molecular formula C₃H₈.
Tidal Energy
Tidal power or tidal energy is a form of hydropower that converts the energy obtained from tides into useful forms of power, mainly electricity.
Wave Energy
Wave power is the capture of energy of wind waves to do useful work – for example, electricity generation, water desalination, or pumping water.
Smog
fog or haze combined with smoke and other atmospheric pollutants.
Acid Precipitation
Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions.
Recycling
Recycling is the process of converting waste materials into new materials and objects.
