Questions and Answers
  • 1. 

    What is not the common cause for a green house effect?

    • A.

      Vehicles

    • B.

      Waste

    • E.

      None of the above

    Correct Answer
    B. Fruits
    Explanation
    The greenhouse effect is primarily caused by the accumulation of greenhouse gases in the atmosphere, such as carbon dioxide and methane, which trap heat from the sun and result in global warming. While vehicles, pollution, and waste contribute to greenhouse gas emissions, fruits do not have a direct impact on the greenhouse effect. Therefore, fruits are not a common cause for the greenhouse effect.

    • E.

      None of the above

    Correct Answer
    D. Ultraviolet radiation
    Explanation
    Ultraviolet radiation is the main reason for the depletion of the ozone hole. Ozone depletion occurs when certain chemicals, such as chlorofluorocarbons (CFCs), are released into the atmosphere. These chemicals break down ozone molecules in the stratosphere when exposed to ultraviolet radiation from the sun. This leads to the formation of the ozone hole, which allows more harmful UV radiation to reach the Earth's surface, posing risks to human health and the environment.
