Questions and Answers

Which of the following best describes the greenhouse effect?

  • The gradual thinning of the ozone layer
  • The increase in the number of humans on Earth
  • The trapping of heat close to Earth's surface by greenhouse gases (correct)
  • The long-term warming of the planet's temperature

    • What is the function of the ozone layer?

  • To convert toxic gases and pollutants in exhaust gas
  • To increase the crop yield
  • To protect the planet from the sun's harmful ultraviolet (UV) radiation (correct)
  • To enhance the water retention capacity of the soil

    • What are CFCs?

  • Exhaust emission control devices that convert toxic gases and pollutants
  • Compounds containing chlorine, fluorine, and carbon used as agents that produce low temperatures (correct)
  • Heat-trapping gases that contribute to the greenhouse effect
  • Additional substances supplied to crops to increase productivity

    • What are the main greenhouse gases responsible for trapping heat near Earth's surface?

    <p>The main greenhouse gases responsible for trapping heat near Earth's surface are carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).</p> Signup and view all the answers

    What is the purpose of a catalytic converter in an exhaust system?

    <p>The purpose of a catalytic converter in an exhaust system is to convert toxic gases and pollutants in the exhaust gas from an internal combustion engine into less-toxic pollutants through a redox reaction.</p> Signup and view all the answers

    How do fertilizers contribute to crop productivity?

    <p>Fertilizers contribute to crop productivity by providing essential nutrients, such as nitrogen, potassium, and phosphorus, that are required by plants. They also enhance the water retention capacity of the soil and increase its fertility.</p> Signup and view all the answers

    Study Notes

    The Greenhouse Effect

    • The greenhouse effect is a natural process that traps heat in the Earth's atmosphere, allowing the planet to maintain a habitable temperature.

    The Ozone Layer

    • The ozone layer's primary function is to absorb UV radiation from the sun, protecting the Earth's surface and its inhabitants from harmful radiation.

    Chlorofluorocarbons (CFCs)

    • CFCs are synthetic compounds used as refrigerants, propellants, and solvents, but they contribute to ozone depletion and are potent greenhouse gases.

    Greenhouse Gases

    • The main greenhouse gases responsible for trapping heat near Earth's surface are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases (such as CFCs).

    Catalytic Converters

    • The purpose of a catalytic converter in an exhaust system is to reduce the emissions of harmful pollutants, such as carbon monoxide, nitrogen oxides, and volatile organic compounds, from internal combustion engines.

    Fertilizers and Crop Productivity

    • Fertilizers contribute to crop productivity by providing essential nutrients, such as nitrogen, phosphorus, and potassium, which promote healthy plant growth and increase crop yields.
