4.1 : Energy and mineral resources

           -tar sands and oil shales
               fuels that come out of tar sands and oil shales could  become good replacements for dwindling    petroleum supplies.
             - formation and mineral deposits
                many of the most important mineral deposits form through igneous processes and hydrothermal solutions. Ore is a an useful metallic mineral.
              -nonmetallic mineral resources
                 nonmetallic mineral resources are tooken away and procesed for the nonmetallic elements they have or for their physical or chemical properties.

  4.2 : alternaate energy souces

            -solar energy
               the two solar energy advantages are that solar energys fuel is free, and it is non-polluting.
            -nuclear energy
              the uranium nuclei split into smaller nuclei snd get neutrons , also heat energy.
            -wind energy
                later on in some decades wind power is only going to be used at between 5 to 10 percent of the electricity used by the country.
           -hydroelectric power
              it is the power generated by falling water
