SECOND LE Flashcards
These are sources that will eventually run out or not be replenished in our lifetime.
Non-renewable resources
Give one example of a non-renewable resource.
Earth minerals, ores, fossil fuels, or nuclear energy
These are naturally occurring compounds found in the Earth’s crust.
Minerals
A deposit in the Earth’s crust of one or more valuable minerals
Ore
The in situ natural concentration of minerals within a geologically defined envelope.
Mineral Resource
The well-explored and defined part of the deposit at a specific cutoff after the completion of detailed exploration.
Mineral reserve
The extraction of deposits from the Earth.
Mining
A type of mining that involves removing minerals from the Earth’s surface.
Open-pit mining
A type of mining that involves extracting minerals from deep underground.
Underground mining
A mineral commonly used in batteries for electric vehicles and electronic devices.
Lithium
A precious metal often used in jewelry and electronics.
Gold
The most common mineral found in the Philippines.
Nickel
A problem associated with mining that involves the leakage of harmful chemicals into the environment.
Leaching of mine wastes (leachate)
Any material that can be changed to release energy in a controlled manner.
Fuel
Give one example of a fuel.
Fossil fuels or alternative fuels
Fuels mined from underground or undersea deposits and include high percentages of carbon.
Fossil fuels
Give one example of a fossil fuel.
Coal, petroleum, or natural gas
The most abundant energy resource in the Earth’s crust.
Coal
Oil found in rocks or sediments.
Petroleum
A fossil fuel that is mainly composed of methane.
Natural gas
A gas produced from the combustion of fossil fuels that contributes to global warming.
Carbon dioxide (CO2)
A type of energy produced by splitting atoms.
Nuclear energy
The country that produces the most nuclear energy
United States
The process of splitting atoms to release energy.
Fission
The location of the Philippines’ unfinished nuclear power plant.
Morong, Bataan
The main component of nuclear waste.
Radioactive water
A common way to dispose of nuclear waste.
Nuclear waste repositories
