    Wind is a ________ source of energy. - ProProfs

    Wind is a ________ source of energy.

    • Renewable

    • Non-renewable

    Correct Answer
    A. Renewable
    Explanation
    Wind is a renewable source of energy because it is generated by the natural movement of air currents, which are constantly replenished by the sun's heat. Unlike non-renewable sources of energy such as fossil fuels, wind energy does not deplete or run out over time. As long as the sun continues to shine and heat the Earth's surface, wind will continue to be generated, making it a sustainable and renewable source of energy.

    Carbon is released into the atmosphere through all of the following ways except ________. - ProProfs

    Carbon is released into the atmosphere through all of the following ways except ________.

    • Respiration

    • Cow flatulence

    • Photosynthesis

    • All of the above

    Correct Answer
    A. Photosynthesis
    Explanation
    Carbon is released into the atmosphere through respiration, where organisms release carbon dioxide as a byproduct of cellular respiration. Cow flatulence also releases methane, a potent greenhouse gas that contains carbon. However, photosynthesis is the process by which plants convert carbon dioxide into oxygen, effectively removing carbon from the atmosphere. Therefore, photosynthesis does not release carbon into the atmosphere, making it the correct answer.
