Resource classification
Semi renewable resources
· E.g. Soil and forests, thought of a renewable as they can
regenerate themselves within a human defined times
frame, although if they are exploited above their natural
rate of replacement then they will become non renewable.
· Water is considered renewable as it is available in vast
quantities around the world. However, some areas struggle
to have enough lean water to meet the rising demand of
their population, meaning water would be non-renewable.
· Therefore the definition of a non renewable resource and
a renewable resource is not often clear cut.…read more

Resource classification
Flow resources
· Renewable resources that don't need regeneration as
they are in constant supply such as wind, solar and
tidal power. Due to problems with cost and technology
these resources have not been used to their full
potential yet. However the use may increase in the
future due to technological advancements and a
increase in demand as non renewables will decrease in
availability.…read more

Resource classification
Non renewable resources
· E.g. Coal, oil, gas which take millions of years to form
and therefore in human terms they are fixed in the
amount available. Resource depletion occurs quickly
and eventually resources become exhausted and no
longer viable for extraction.
Natural resources
· Can also be classified as abiotic or biotic. Biotic come
from living organisms such as wood. Abiotic do not
come from living organisms and these are resources
such as iron and copper.…read more

commercially exploitable values under known
· The supply of the mineral is the amount that an be
