Geography- Term 4- Unit 1: Resources use Flashcards
what do geographers understand resources as?
the natural resources that support economic development
Define resources (other definition)
things that a country can use,e.g. minerals, fish & timber
define natural resources
resources which occur from nature and are not man-made
give examples of natural resources
minerals, soil, forests, fish stocks, wildlife, tourist attractions
explain why the possession of resources doesn’t necessarily lead to economic development
having resources doesn’t always lead to economic development. It is about how efficiently the resources are used. If they are depleted quickly, the country will have to start to buy from other countries and lose that money that could have lead to further economic development, e.g. better infrastructure. If they don’t have the factories to manufacture tertiary or secondary products from the resources, then they sell the resources and re-buy the finished product at a more expensive price.
what affects how much of resources will be left for future use?
the amount of resources used and the rate at which they are used
what are renewable resources?
they are resources that are able to replace themselves
what are non-renewable resources?
they can only be used once and don’t replace themselves
define exploitation
use of resources
how does over-exploitation happen?
when renewable resources are used faster than they can replace themselves.
what is depletion and how does it happen?
depletion means reducing by a large amount so that there is not enough left. this happens when reserves are used up so rapidly that the available amount is reduced or finished
when does over-fishing occur?
it occurs when fish are caught in such large quantities that their numbers become depleted.
what does over-fishing result in?
depletion of fish stocks
define stocks
it is the total amount of something that is available for use
how does the scale of over-fishing vary?
It can be localised and only affect a specific coastal region or even a lake. or it can occur on a large scale and affect a particular part of the ocean, entire sea or worldwide stocks
