    3. 3. Earth☺ The Crust☺ The Mantle☺ The Outer Core☺ The Inner CoreThe CrustSurface (5 miles thick)☺ Cool☺ Hard8/31/2012 3
    4. 4. Core☺ Very big (1400 miles radius)☺ Lots of iron and nickel☺ Hot like the sun☺ Enormous pressure☺ Liquid/SolidMantle☺ Most of Earth (82%)☺ Rock (1800 miles deep)☺ Hot enough to melt most rocks☺ High pressure (3 times higher)☺ Solid with some fluid movement at surface8/31/2012 4
    5. 5. Why Study Geology? • Mitigating Geologic Hazards • Earthquakes • Volcanoes • Supplying Things We Need • Metals • Minerals • Petroleum • Protecting the Environment • Water cycle • Global Change: Warming and Sea level rise • Understanding Our Surroundings • The Earth’s relationship to other planets8/31/2012• Geological Time 5
    6. 6. A View of Earth• Earth is a planet that is small and self contained Earth’s four spheres• Hydrosphere• Atmosphere• Biosphere• Solid Earth8/31/2012 6
    7. 7. AtmosphereFrom Earth’s surface to outer space ☺ 50 miles (Highline to Rocky Mountain National Park) ☺ Composition ☺80% Nitrogen ☺20% oxygen ☺Other gases…8/31/2012 7

    10. 10. What is Space Station??• Research facility in space being assembled in Low Earth Orbit• A complete home to the humans beyond the Earth• Two space stations are in orbit; the International space station, and Chinas Tiangong 18/31/2012 10
    11. 11. It includes• Joint project between NASA (USA), JAXA (Japan), RKA (Russia), ESA(Europe), CSA (Canada) and small contributions from others• Effects of long-term space exposure on the human body• Ultrasound scans and diagnosis and treatment of medical conditions in space• Study on cosmic rays, cosmic dust, antimatter and dark matter in the universe8/31/2012 11
    12. 12. Construction of ISS & ISSModules• ISS construction started with the help of Russian Space Station Mir on 20 November 1998 and is scheduled to complete by 2011 end• Zarya(20.11.1998)• Unity node• Zvezda (Russia)• Destiny (U.S Laboratory)8/31/2012 12
    13. 13. Power Supply• The source of electrical power for the ISS is the sun• Sunlight is converted into electricity by solar arrays.• Solar arrays are arranged as four pairs of wings, and each wing is capable of generating nearly 32.8 kW of DC power• Has rechargeable nickel-hydrogen batteries working life of 6 years8/31/2012 13
    14. 14. ConclusionEnsure that a quality future will be left to our children aswe make difficult decisions regarding natural resourceconsumption.8/31/2012 14
