Unit 8 Earth enviornmental Flashcards
Natural Resources
Conservation
Protecting and preserving natural resources and the environment
Photosynthesis
Conversion of light energy from the sun into chemical energy.
Fission
A nuclear reaction in which a massive nucleus splits into smaller nuclei with the simultaneous release of energy
Fusion
Creation of energy by joining the nuclei of two hydrogen atoms to form helium.
Ecological Footprint
the impact of a person or community on the environment, expressed as the amount of land required to sustain their use of natural resources.
Sustainibilty
The ability to keep in existence or maintain. A sustainable ecosystem is one that can be maintained
Electromagnetic radiation
a form of energy that exhibits wavelike behavior as it travels through space
Fossil Fuels
Coal, oil, natural gas, and other fuels that are ancient remains of plants and animals.
Non-renewable resources
a resource that cannot be reused or replaced easily (ex. gems, iron, copper, fossil fuels)
Renewable resources
A natural resource that can be replaced at the same rate at which the resource is consumed
Solar Power
energy from the sun that is converted into thermal or electrical energy
Wind power
The use of a windmill to drive an electric generator
Biofuel
Fuel from organic sources
Nuclear power
electric or motive power generated by a nuclear reactor.
Energy
The ability to do work or cause change
electricity
A form of energy caused by the movement of electrons.
Fuel cells
an electrochemical cell that uses replenishable substances such as hydrogen or oxygen or water to produce electricity
Impact
(n) the striking of one object against another; the shock caused by a collision; (v.) to affect especially forcefully
geothermal
Of, relating to, or produced by the internal heat of the earth
tidal and wave energy
energy from tides and ocean waves; renewable
recycle
The process of making new products from materials that were used in another product.
Reuse
to use again
Reduce
to make smaller
Tar Sands/ Oil shale
Not viable energy resources
Nonconventional resources
