Define finite resource.
A finite resource is a natural resource that people use up faster than it is replaced.
True or False?
Fossil fuels, minerals and metals are all examples of finite resources.
True.
They exist in limited amounts and cannot be replaced within a human timescale.
Define depletion.
Depletion is the reduction or exhaustion of the available supply of a resource.
Which two problems does careful use of finite resources help reduce?
Careful use of finite resources helps reduce environmental damage and resource shortages.
Define sustainable resource management.
Sustainable resource management meets the needs of the present generation without stopping future generations from meeting their own needs.
Sustainable resource management helps maintain a between economic growth and environmental protection.
Sustainable resource management helps maintain a balance between economic growth and environmental protection.
Which two practices does sustainable resource management encourage to cut waste?
Sustainable resource management encourages reuse and recycling to cut waste.
True or False?
Sustainable resource management favours short-term gain over long-term planning.
False.
It encourages long-term planning rather than short-term gain.
What two things does sustainable resource management include developing?
Sustainable resource management includes developing alternative materials and renewable resources.
Define reuse.
Reuse means using rock, ore or mineral materials again instead of throwing them away.
How can manufacturers reduce the metal used in packaging?
Manufacturers can make thinner metal packaging, such as cans that use less aluminium or steel.
True or False?
Recycling aluminium drink cans uses more energy than extracting new aluminium from ore.
False.
Recycling aluminium uses only a small fraction of the energy needed to extract new metal from ore.
Which three factors encourage people to recycle mineral-based materials?
Accessibility, ease and education all encourage people to recycle.
Define efficient extraction.
Efficient extraction means getting more useful material from each tonne of ore or rock.
Which ores can improved processing techniques make worth mining?
Improved processing techniques can recover more copper from low-grade ores that were once too poor to mine.
True or False?
More efficient extraction methods mean that more mines are needed.
False.
Efficient methods mean fewer mines can produce the same amount of material.
Define resource depletion.
Resource depletion happens when people use up rocks, ores or minerals faster than they can be replaced.
Define legislation.
Legislation is the set of laws that control how and where mining and quarrying take place.
What limit can governments set to slow resource depletion?
Governments can limit how much ore or rock companies extract each year.
What can laws require after quarrying ends?
Laws can require land restoration, such as replanting trees or filling open pits.
Regular check that mining companies meet environmental standards.
Regular inspections check that mining companies meet environmental standards.
Which penalties can authorities use when mining companies break environmental rules?
Authorities can use fines or closure orders when mining companies break the rules.
Define alternative materials.
Alternative materials are other substances used instead of minerals from rocks and ores.
Which materials can sometimes replace metal in pipes, window frames or car panels?
Plastics or composites can sometimes replace metal in these products.
True or False?
Manufacturers can make concrete substitutes from industrial waste.
True.
Concrete substitutes made from industrial waste or recycled aggregates reduce the need for fresh stone from quarries.
What economic benefit do companies gain from recycling materials?
Companies save money by recycling materials and using them efficiently.
Why can reducing mineral extraction harm some local economies?
Reducing extraction can harm local economies because, in some countries, mining provides jobs and income.
True or False?
Metal alloys are among the easiest materials to recycle.
False.
Metal alloys are harder to recycle effectively while keeping their original quality.
Weak of mining laws can allow overextraction to continue.
Weak enforcement of mining laws can allow overextraction to continue.
Which missing services limit recycling in some areas?
Some areas lack recycling centres or collection services, which limits recycling.
Why is modern recycling or efficient extraction technology a limitation?
Modern recycling and efficient extraction technology can be expensive to install and maintain.
