    Rock cycle Rock cycle Presentation Transcript

    • The Rock Cycle Thinking about relationships among the major rock groups
    • Major Rock Groups
      • Igneous
        • Formed from a melt (molten rock)
        • Plutonic (intrusive):slow cooling and crystallization
        • Volcanic (extrusion): quick cooling at the surface
      • Sedimentary
        • Formed at the Earth’s surface
        • Clastic (Mineral Fragments or grains, clays)
        • Chemical (crystalline chemical/biochemical precipitates)
      • Metamorphic
        • Changed by pressure, temperature and fluids.

      • The rock cycle demonstrates the relationships among the three major rock groups
      • It is powered by the interior heat of the Earth
      • As well as earth’s momentum and…
      • The energy from the sun
      • It involves processes on the Earth’s surface as well as the Earth’s interior
      • It connects the “hydrologic cycle” with the “tectonic cycle”.
      In Conclusion…
