where does natural resources come from?
how can natural resources form?
how can natural products be replaced give an example
what does agriculture provide eg?
-Natural resources come from earth,sea and air.Examples cotton for clothing oil for fuel.
-They can form without human input
-They can be replaced by synthetic products or improved upon by man-made processes.Example rubber is a natural product extracted from sap of the tree.However man made polymers have now been made which can replace rubber in uses such as tyre’s
-Agriculture provides conditions where natural resources can be enhanced for our needs eg development of fertiliser’s means you can produce a high yield of crops
what is renewable resources and eg?
what is finite non renewable resources and examples’s?
what happens to non-renewable resources after they have been extracted?
-Renewable resources reform at a similar rate to,or faster than,we use them eg timber,fresh food and water
-Finite resources aren’t formed quickly enough to be considered replaceable.
They include:
-Fossil fuels
-Nuclear fuels such as uranium and plutonium
-Minerals and metals found in ores in the earth
-After finite resources get extracted many undergo man-made processes to provide fuels and materials necessary for modern life
what risk finite resources have?
-for mining metal ores is bad for the environment uses loads of energy scars the landscape produces lots of waste destroys habitats
how to interpet information about different resources in the graph?
-By suggesting which one is renewable and non-renewable
-finite takes lots of time whereas renewable takes short but faster than finite
