Finite and renewable resources Flashcards
What’s a natural resource? INC example
formed without human input. They include anything that comes from the earth, sea or air. For example: cotton
What are some of these natural resources replaced by? INC example
synthetic products or improved upon by man-made processes.
For example rubber is a natural resource extracted from sap of a tree but man-made polymers have now been made which can replace rubber in uses such as tyres.

INC example
Agriculture, conditions, natural resources , enhanced, needs
- development of fertilisers -> high yield of crops
Define renewable resources INC example
reform at a similar rate to or faster than we use them, For example, Timber as trees can be planted following a harvest and take a few years to regrow
Define Finite non-renewable resources INC example
aren’t formed quickly enough to be considered replaceable
Finite resources include fossil fuels and nuclear fuels such as uranium and plutonium. Minerals and metals found in ores in the earth are also be non-renewable materials
What happens to many finite resources after they’re extracted
undergo man- made process to provide fuels and materials necessary for modern life. For example: fractional distillation is used to produce usable products such as petrol from crude oil and metal ores are reduced to produce a pure metal
Extracting finite resources have risks (1-3)
1) Many modern materials are made from raw, finite resources, for example most plastics, metals and building materials
2) People have to balance the social, economic and environmental effects of extracting finite resources
3) For example, mining metal ores is good because useful products can be made. It also provides local people with jobs and brings money into the area however its bad for the environment as it uses loads of energy, scars the landscape, produces lots of waste and destroys habitats.
