Geology and Nonrenewable Mineral Resources

geology: study of dynamic processes occurring on earth's surface
1. earth
  1. layers
    1. core: super hot solid inner surr. by liquid
    2. mantle: solid w/ liquid
      1. asthenosphere
    3. crust: thin solid layer floating on liquidy substance
      1. continental crust (less dense)
      2. oceanic crust (more dense and more)
  2. geologic processes
    1. earthquakes
      1. typically transform faults grinding against each other, both on the continental and oceanic crust
    2. tsunami
      1. underwater (oceanic crust) movement
    3. volcanoes
      1. plates diverge, allowing CO2 to rise
  3. tectonic plates
    1. plate boundaries
      1. divergent
      2. convergent
      3. transform fault
minerals: solid inorganic elements and compounds
1. fossil fuels, aluminum, copper, limestone, sand
2. types of min resources
  1. identified and known
  2. reserves
  3. undiscovered reserves, assumed to be there
  4. undiscovered and unknown
types of rocks
1. igneous: molten rock wells up + hardens, makes up most of crust
2. metamorphic: preexisting rock is put to the test
3. sedimentary: layers up
