Reference: AQA
Resources that will eventually run out if extraction continues at current rates, because they form over geological timescales but are extracted and used much faster than they are replaced.
Resources that are being depleted faster than they are naturally replaced, such as fossil fuels and metal ores.
Crude oil is a finite resource, so alternative energy sources and conservation are important considerations.
Resources that are being used up faster than they form and cannot be replaced on a human timescale.
