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
