    Greenhouse Effect Power Point Greenhouse Effect Power Point Presentation Transcript

    • Greenhouse Effect and Global Warming
        • Rise in Earth’s temperature
        • By certain atmospheric gases
        • That trap the Sun’s energy
      What is the Greenhouse Effect?
    • Examples of Heat Trapping Gases
      • Water vapor (H 2 O)
      • Carbon dioxide (CO 2 )
      • Nitrous oxide (N 2 O)
      • Methane (CH 4 )
    • Why are the Gases Important?
      • Heat would escape back into space
      • Earth’s temperature would be 60 ºF colder
      • Makes Earth suitable for life
    • Greenhouse Effect Examples:
      • Trap heat from sun
      • Glass lets in light
      • Glass keeps heat from escaping
      • Causes greenhouse to heat up
      Greenhouse
    • Greenhouse Effect Examples:
      • Glass lets in light
      • Glass keeps heat from escaping
      • Causes the car to heat up
      Car Parked in Sunlight
    • Process of the Greenhouse Effect
    • Process of the Greenhouse Effect
      • Sun’s energy passes through atmosphere
      • 26% is reflected or scattered
      • 19% absorbed by clouds, gases, and particles
      • 4% reflected to space by surface
      • 51% reaches the surface
    • What is the Energy Used for?
      • Heating of the ground
      • Melting of ice and snow
      • Evaporation of water
      • Plant photosynthesis
    • Possible Causes of the Greenhouse Effect
      • Deforestation and agriculture
      • Burning of fossil fuels, gasoline, oil
      • Burning of wood and coal
      • CFC’s
      • Population Growth
    • A Better Look... http://earthguide.ucsd.edu/earthguide/diagrams/greenhouse/
    • Why is it Dangerous?
      • Global Warming
      • Endangered Species
      • Climate Change
    • What is Global Warming?
      • Heat trapped inside Earth
      • General warming effect created
      • Increase in air and ocean temperatures
      • Vital issue in society
    • Causes of Global Warming
      • Greenhouse gases increase through human activity
      • Deforestation
      • Use of fertilizers
      • Burning of organic matter
      • Burning of fossil fuels
    • Consequences of Global Warming
      • Climate changes
      • Changes in wildlife adaptations and cycles
      • Melting of polar ice caps
      • Increase in sea level
      • Flooding in coastal areas
      • Ocean Acidification
    • More Consequences
      • Species becoming endangered/extinct
      • Heavy drought
      • Spread of disease
      • Rise in tides
      • Change in weather patterns
    • Future Outlook of Glabal Warming
      • Natural resources depleted
      • Need balance between environment and industry
      • Greenhouse gas emissions reduced by 80%
    • What Can We Do to Help?
      • Reforestation
      • Personal Actions
      • Climate Policy
    •  
      • Put notes away
      • Pull out a sheet of paper
      • Answer the following questions
        • Describe the greenhouse effect
        • List the possible causes of greenhouse effect
        • List the possible causes of global warming
        • List the consequences of global warming
