Questions and Answers
  • 1. 

    Which country currently emits the most greenhouse gases?

    • A.

      India

    • B.

      China

    • C.

      U.K

    • D.

      U.S

    Correct Answer
    B. China
    Explanation
    China is currently the country that emits the most greenhouse gases. This is due to its large population and rapid industrialization over the past few decades. China's heavy reliance on coal for energy production is a major contributor to its high greenhouse gas emissions. Additionally, China is the world's largest manufacturer and exporter of goods, which also contributes to its carbon footprint.

    Which of the following light bulb types uses the least energy, and therefore results in fewer greenhouse gas emissions?

    • A.

      Incandescent

    • B.

      Compact florescent

    • C.

      Halogen

    • D.

      All of the above

    Correct Answer
    B. Compact florescent
    Explanation
    Compact fluorescent light bulbs use the least energy compared to incandescent and halogen bulbs. This is because compact fluorescent bulbs are more energy-efficient and convert more energy into light rather than heat. As a result, they require less electricity to produce the same amount of light, leading to lower greenhouse gas emissions.

    • D.

      1,500,000

    Correct Answer
    C. 150,000
    Explanation
    The World Health Organization attributes 150,000 human deaths per year to climate change.

    Rate this question:

  • 4. 

    How long does it take for CO2 in the atmosphere to scatter?

    • A.

      1 year

    • B.

      10 years

    • C.

      50 years

    • D.

      100 years

    Correct Answer
    D. 100 years
    Explanation
    CO2 in the atmosphere takes approximately 100 years to scatter. This means that it takes a century for the CO2 molecules to disperse or spread out evenly throughout the atmosphere. During this time, the CO2 can have various impacts on the climate and environment, such as contributing to global warming and ocean acidification.

  • 5. 

    What type of supermarket bag is more eco-friendly, paper or plastic?  

    • A.

      Paper

    • B.

      Plastic

    • C.

      Either is fine

    • D.

      None of the above

    Correct Answer
    D. None of the above
    Explanation
    The question is asking which type of supermarket bag is more eco-friendly, paper or plastic. However, the correct answer is "None of the above" because both paper and plastic bags have negative environmental impacts. Paper bags contribute to deforestation and require a large amount of energy and water to produce. On the other hand, plastic bags are made from non-renewable resources, take hundreds of years to decompose, and contribute to pollution and harm to wildlife. Therefore, neither option is considered to be more eco-friendly.

    Today, most places on Earth are warmer than they used to be 100 years ago.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The given statement is true because global temperatures have been steadily rising over the past century. This increase in temperature is primarily due to human activities, such as the burning of fossil fuels and deforestation, which release greenhouse gases into the atmosphere. These greenhouse gases trap heat and cause the Earth's temperature to rise. This phenomenon, known as global warming, has resulted in various impacts, including melting ice caps, rising sea levels, and more frequent extreme weather events. Therefore, it is accurate to say that most places on Earth are warmer now compared to 100 years ago.

    In the deep ocean, carbon is stored in the largest amounts on Earth.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    In the deep ocean, carbon is stored in the largest amounts on Earth. This is because the ocean acts as a carbon sink, absorbing and storing large quantities of carbon dioxide from the atmosphere. The deep ocean contains a significant portion of this stored carbon, which is sequestered in the form of dissolved carbon dioxide and organic matter. This carbon storage in the deep ocean plays a crucial role in regulating the Earth's climate by reducing the amount of carbon dioxide in the atmosphere, thereby mitigating the effects of climate change.

    How do scientists collect evidence about climate?

    • A.

      Using ground-based measurements of surface temperature, carbon dioxide concentration, and sea level

    • B.

      By using remote sensing from space with satellites

    • C.

      By collecting "proxy data" from tree rings, ice cores, and historical records

    • D.

      By using all of these points

    Correct Answer
    D. By using all of these points
    Explanation
    Scientists collect evidence about climate by using a combination of ground-based measurements, remote sensing from space with satellites, and collecting "proxy data" from tree rings, ice cores, and historical records. Ground-based measurements provide direct observations of surface temperature, carbon dioxide concentration, and sea level. Remote sensing from space allows scientists to gather data on a larger scale and monitor changes over time. Proxy data, such as tree rings and ice cores, provide information about past climate conditions. By using all of these points, scientists can gather a comprehensive understanding of climate patterns and changes over time.

    Which of the following is a greenhouse gas?

    • A.

      CH4

    • B.

      Water vapor

    • C.

      O3

    • D.

      All of the above

    Correct Answer
    D. All of the above
    Explanation
    All of the options listed (CH4, water vapor, and O3) are greenhouse gases. Greenhouse gases are gases in the Earth's atmosphere that trap heat from the sun and contribute to the greenhouse effect, leading to global warming. Methane (CH4) is a potent greenhouse gas released from various human activities and natural processes. Water vapor is the most abundant greenhouse gas, and it plays a significant role in regulating the Earth's temperature. Ozone (O3) is a greenhouse gas found in the Earth's stratosphere, where it helps protect us from harmful ultraviolet (UV) radiation.

    Wasting less food is one of the ways to reduce greenhouse gas emissions.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Wasting less food can indeed help reduce greenhouse gas emissions. When food is wasted, it ends up in landfills where it decomposes and produces methane, a potent greenhouse gas. Additionally, the production and transportation of food require energy, which often comes from fossil fuels and contributes to greenhouse gas emissions. By reducing food waste, we can minimize the amount of methane released and decrease the overall carbon footprint associated with food production and consumption.
