energy mineral resources (LEC 11) Flashcards
renewable resources can be replenished over relatively short time spans. what are some examples
food
trees
energy from water, sun, wind
non renewable energy form continuously but slowly. what are some examples
fuels (coal, oil, natural gas)
metals (iron, copper, uranium, gold)
what is an oil trap
a geologic environment that allows economically significant amounts of oil and gas to accumulate underground
what is a reservoir rock
a porous and permeable rock that contains petroleum and natural gas
whats a cap rock
impermeable to oil and gas, prevents it from escaping
hydraulic fracturing – also called fracking. what is this
- huge quantities of oil can be trapped in impermeable rock
- fluids (mixture of water, sand and chemicals) are pumped into the impermeable rock at high pressures
- opens cracks and keeps them open for gas and oil to flow up to the surface
- can trigger minor earthquakes and cause groundwater contamination
___________ is the primary fuel for most nuclear power plants. its readily fissionable and the only naturally occurring isotope. doesnt emit CO2
Uranium-235
when the wind blows, it contains kinetic energy, what type of energy is this
wind energy
what is hydroelectric power
power generated by falling water which drives turbines that produce electricity
energy is from heat within the earth is called
geothermal energy
what is biomass energy
energy from plants and animals
power produced by the surge of ocean waters during the rise and fall of tides. what type of power is this
tidal power
____________________ or _____________________ may cause a deposit to become profitable or lose its profitability
technological advances
economical changes
what are mineral resources
mineral resources are the useful minerals that are available commercially
___________ are already identified deposits from which minerals can be extracted profitably
reserves
an _____ is a deposit that has naturally occurring concentration of one or more metallic minerals that can be extracted for economic goods
ore
what are the main metallic mineral deposits (5)
- magmatic differentiation
- hydrothermal deposits
- metamorphic deposits
- weathering deposits
- placer deposits
earth materials that are not used for fuels, or processed for metals. they are used in the process in creating other products. what are they called
non-metallic mineral resources
non-metallic mineral resources are divided into two groups which are:
building materials
industrial minerals
NOTE: substances like limestone have so many uses and fall into both categories
