    Study Notes

    Greenhouse Effect

    • The greenhouse effect is a natural process where heat absorbing components of the atmosphere trap infrared radiation (IR) emitted from the Earth.
    • Nitrogen and oxygen do not absorb much IR.
    • Carbon dioxide and water vapor are major greenhouse gases.
    • Greenhouse gases absorb IR and re-emit it, warming the surrounding air.
    • The greenhouse effect is essential for life on Earth, as it prevents the planet from becoming too cold.
    • Human activities are increasing the concentration of greenhouse gases in the atmosphere, leading to global warming.

    Global Warming

    • Global warming is the increase in average global temperatures that results from the greenhouse effect.
    • Burning fossil fuels releases carbon dioxide, a major greenhouse gas.
    • Deforestation reduces the number of trees available to absorb carbon dioxide from the atmosphere.
    • Agricultural practices, such as livestock production, release methane, another greenhouse gas.

    Effects of Global Warming

    • Climate change, a long-term change in weather patterns, is a result of global warming.
    • Melting of ice sheets and glaciers leads to rising sea levels and coastal submersion.
    • Extreme weather events, such as intense storms and droughts, are becoming more frequent and severe.
    • Shifts in climate affect biodiversity and ecological balance.
    • Food production is threatened by changes in climate.
    • Acidification of waterways can lead to the death of aquatic organisms.

    Solutions to Acid Deposition

    • Cleanup strategies involve neutralizing acidified lakes.
    • Prevention strategies include using renewable energy sources and enacting laws against air pollution.

    Ozone Layer Depletion

    • Ozone (O3) in the stratosphere protects life on Earth from harmful solar radiation.
    • Chlorofluorocarbons (CFCs) and other ozone-depleting substances cause depletion of the ozone layer.
    • Ozone depletion leads to increases in ultraviolet radiation reaching the Earth's surface.

    Effects Of Ozone Depletion

    • Increased incidence of skin cancer.
    • Weakened immune systems.
    • Reduced photosynthesis in plants
    • Damage to crops
    • Increased evaporation, reduced soil moisture

    Protecting The Ozone Layer

    • The Montreal Protocol, a landmark agreement signed in 1987, aims to phase out ozone-depleting substances.
    • The ozone layer is recovering as a result of the Montreal Protocol.
