Natural resources
Natural Resources

  • IsanythingfromtheEarththatpeople use in meetingtheirneedsforfood, clothing, and shelter.

  • Examples of theseresourcesincludesoil, water, minerals, and vegetation.


Raw materials
RawMaterials

  • People use someresourcesjustthewaythey come fromnature. Waterisoneexample.

  • Butmostresoucesmustbechanged in somewaytomakesomethinguseful. Theseresources are calledrawmaterials.

  • Theymustbeprocessedtomakethemintousefulmaterialssuch as paper and lumber.


Three kinds of resources

ThreeKinds of Resources

  • Geographers divide theEarth’s natural resourcesintothreegroups.


1 recycable resources
1.- RecycableResources

  • Water, nitrogen, and carbon are examples of recycableresources.

    • Theseresourcesrecyclethroughourenvironmentnaturally. Thewatercycle, forinstance, naturallyrecyclesourfreshwatersupply.


2 renewable resources
2.- RenewableResources

  • Trees and other living thingsontheEarth.

    • Theseresources are differentfromrecycableresourcesbecausethey can bereplaced.

      Example: A timbercompanymayharvestallthetrees in anarea. Ifthecompanyplants new treestoreplacethem, however, they are renewingtheresource.

3 nonrenewable resources
3.- NonrenewableResources

  • Whentheseresources are used up, theycannotbereplaced. -Most non living things, such as minerals, coal, natural gas, and petroleum, are non renewableresources.


Ancient energy fossil fuels
AncientEnergy: FossilFuels

  • Fossilfuelswerecreatedovermillions of yearsfromtheremains of prehistoricplants and animals.

  • Thesefuels are no longerbeingcreated. As a result, fossilfuels are non renewableresources.


Energy resources
EnergyResources

  • Everyone in theworldneedsenergy. Certainareas are rich in someenergyresources, whileothershaveveryfew.

  • CountrieslikeSaudi Arabia and Mexicohavehugeamounts of oil.

  • Otherslikethe U.S.A. and China, havecoal and natural gas.

  • CountrieswithmanyriverslikenorthwesternEurope, can use waterenergytocreateelectricity. Otherssuch as Japan, haveveryfewenergysources.
