    By 2100 AD, global temperature is expected to rise by about 2 °C and consequently, the sea level by about 50 cm from the present level. How is a rise in temperature expected to increase the level of the sea?

    • By expanding ocean water

    • By melting mountain glaciers

    • By causing ice sheets of Antarctica and Greenland to melt and slide into the oceans

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    A rise in temperature is expected to increase the level of the sea through multiple mechanisms. Firstly, as temperatures rise, ocean water expands due to thermal expansion, causing the sea level to rise. Secondly, higher temperatures lead to the melting of mountain glaciers, which adds more water to the oceans and contributes to sea level rise. Lastly, the warming of the Earth also causes the ice sheets of Antarctica and Greenland to melt and slide into the oceans, further increasing the sea level. Therefore, all of the above factors contribute to the rise in sea level due to a rise in temperature.

    Which of the following is responsible for turning yellow Taj Mahal?

    • Nitrogen dioxide

    • Sulphur

    • Chlorine

    • Sulphur dioxide

    Correct Answer
    A. Sulphur dioxide
    Explanation
    Sulphur dioxide is responsible for turning the Taj Mahal yellow. Sulphur dioxide is released into the atmosphere through the burning of fossil fuels, industrial processes, and vehicle emissions. When sulphur dioxide combines with moisture in the air, it forms sulphuric acid. This acid then reacts with the marble of the Taj Mahal, causing it to turn yellow over time. This phenomenon, known as marble discoloration, is a major concern for the preservation of the Taj Mahal and other historical monuments.

    Exposure to indoor second hand smoke, dirty cooking fuel, and dampness increases the risk of which infectious disease in children? - ProProfs

    Exposure to indoor second hand smoke, dirty cooking fuel, and dampness increases the risk of which infectious disease in children?

    • Tuberculosis

    • Malaria

    • Mumps

    • Cholera

    Correct Answer
    A. Tuberculosis
    Explanation
    Exposure to indoor second hand smoke, dirty cooking fuel, and dampness increases the risk of tuberculosis in children. Tuberculosis is an infectious disease caused by the bacteria Mycobacterium tuberculosis, which primarily affects the lungs but can also affect other parts of the body. Second hand smoke can weaken the immune system, making children more susceptible to tuberculosis. Dirty cooking fuel, such as coal or wood, can release harmful pollutants that can damage the lungs and increase the risk of developing tuberculosis. Dampness in indoor environments can promote the growth of mold and bacteria, which can also contribute to the development of tuberculosis.

    The supersonic jets cause pollution by the thinning of?

    • CO2 layer

    • SO2 layer

    • O2 layer

    • O3 layer

    Correct Answer
    A. O3 layer
    Explanation
    Supersonic jets cause pollution by thinning the O3 layer, also known as the ozone layer. Ozone is a gas that forms a protective layer in the Earth's stratosphere, shielding the planet from harmful ultraviolet (UV) radiation. However, the emissions from supersonic jets, such as nitrogen oxides (NOx), can react with ozone molecules, leading to their depletion. This thinning of the ozone layer allows more UV radiation to reach the Earth's surface, which can have detrimental effects on human health and the environment.

    Which of the following forest landscape restoration activities is the most efficient at removing carbon from the atmosphere? - ProProfs

    Which of the following forest landscape restoration activities is the most efficient at removing carbon from the atmosphere?

    • Agroforestry

    • Magrove restoration

    • Planted forests and woodlots

    • Natural regeneration

    Correct Answer
    A. Planted forests and woodlots
    Explanation
    Planted forests and woodlots are the most efficient at removing carbon from the atmosphere because they involve intentionally planting trees, which are known to absorb and store carbon dioxide through the process of photosynthesis. This method allows for a controlled and targeted approach to carbon sequestration, as specific tree species can be selected and managed for optimal carbon storage. In contrast, agroforestry combines agricultural and forestry practices, magrove restoration focuses on coastal ecosystems, and natural regeneration relies on the spontaneous regrowth of forests, all of which may have varying levels of effectiveness in removing carbon from the atmosphere.

    Aerosol optical depth is a measure of how much sunlight is absorbed or reflected by the Earth’s atmosphere. A value of 0 indicates perfectly clear skies and a value of 1 indicates no sunlight penetration. What value between 0 and 1 has been deemed the “safe operating space” for humanity?

    • Less than or equal to 0.15

    • Less than or equal to 0.25

    • Less than or equal to 0.35

    • Less than or equal to 0.50

    Correct Answer
    A. Less than or equal to 0.25
    Explanation
    The "safe operating space" for humanity in terms of aerosol optical depth is a value that is less than or equal to 0.25. This means that as long as the aerosol optical depth remains below or equal to 0.25, the amount of sunlight absorbed or reflected by the Earth's atmosphere is within a range that is considered safe for human activities. Higher values would indicate increased levels of sunlight penetration, which could have potential negative impacts on the environment and human health.
