    Which of the following parts of the solar spectrum provides the energy that powers photosynthesis? - ProProfs

    Which of the following parts of the solar spectrum provides the energy that powers photosynthesis?

    • Infrared

    • Visible light

    • Ultraviolet

    • Radio waves

    Correct Answer
    A. Visible light
    Explanation
    Visible light is the correct answer because it falls within the wavelength range of 400-700 nanometers, which is the range that plants are able to absorb and utilize for photosynthesis. In this process, plants convert light energy into chemical energy, which is essential for their growth and survival. Infrared, ultraviolet, and radio waves do not fall within this specific wavelength range and therefore do not provide the necessary energy for photosynthesis.

    Unlike water or sound waves, electromagnetic raditation - ProProfs

    Unlike water or sound waves, electromagnetic raditation

    • Has frequency

    • Has wavelength

    • Can travel through a vacuum

    • Is always dangerous and should be avoided

    Correct Answer
    A. Can travel through a vacuum
    Explanation
    Electromagnetic radiation refers to the energy that is transmitted through electromagnetic waves, such as radio waves, microwaves, visible light, and X-rays. Unlike water or sound waves, which require a medium to travel through, electromagnetic radiation can travel through a vacuum, which is a space devoid of matter. This is because electromagnetic waves consist of oscillating electric and magnetic fields that do not rely on physical particles for propagation. Therefore, electromagnetic radiation can travel through empty space, making it distinct from other types of waves.

    Which source of greenhouse gases produces a significant amount of methane that is released into the atmosphere?

    • Metal refining

    • Forests

    • Agricultural livestock

    • Railroads

    Correct Answer
    A. Agricultural livestock
    Explanation
    Agricultural livestock, such as cows and sheep, produce a significant amount of methane that is released into the atmosphere. This is because these animals have a digestive system that breaks down food through fermentation, resulting in the release of methane gas as a byproduct. Methane is a potent greenhouse gas that contributes to climate change and global warming. Therefore, agricultural livestock are a major source of methane emissions and play a significant role in the overall greenhouse gas production.

    Which of these phrases best describes frequency? - ProProfs

    Which of these phrases best describes frequency?

    • The number of waves that pass a given reference point per second

    • The distance between the same point on two successive waves

    • The rate of vibrations of waves

    • The time necessary for one wave to pass a particular point

    Correct Answer
    A. The number of waves that pass a given reference point per second
    Explanation
    Frequency is a measure of how often something occurs. In the context of waves, it refers to the number of waves that pass a given reference point per second. This means that it measures the rate at which the waves are occurring, rather than the distance between the waves or the time it takes for one wave to pass a particular point. Therefore, the phrase "the number of waves that pass a given reference point per second" best describes frequency.

    Where is the largest amount of Earth's carbon located? - ProProfs

    Where is the largest amount of Earth's carbon located?

    • In human cells and bones

    • In CO2 dissolved in the oceans

    • In fossils and carbonate rocks

    • In living animals and plants

    Correct Answer
    A. In CO2 dissolved in the oceans
    Explanation
    The largest amount of Earth's carbon is located in CO2 dissolved in the oceans. This is because the oceans act as a carbon sink, absorbing carbon dioxide from the atmosphere through a process called carbon sequestration. The dissolved CO2 in the oceans plays a crucial role in regulating the Earth's climate by reducing the amount of greenhouse gases in the atmosphere. Additionally, the oceans also support various marine organisms that incorporate carbon into their shells and tissues, further contributing to the carbon storage in the oceans.

    • 15%

    • 30%

    • 45%

    • 70%

    Correct Answer
    A. 30%
    Explanation
    Approximately 30% of the Sun's energy never enters the Earth's atmosphere and is reflected back into space. This is due to a phenomenon called albedo, which refers to the reflection of solar radiation off the Earth's surface, clouds, and other atmospheric particles. The reflectivity of different surfaces and objects on Earth, such as ice, snow, and clouds, determines the amount of energy that is reflected back into space.

    Which has the highest energy and therefore may be most harmful?

    • Cosmic rays

    • Ultraviolet rays

    • Infrared rays

    • Radio waves

    Correct Answer
    A. Cosmic rays
    Explanation
    Cosmic rays have the highest energy among the given options, which makes them potentially more harmful. Unlike the other types of radiation mentioned, cosmic rays originate from outer space and consist of high-energy particles, such as protons and atomic nuclei, traveling at nearly the speed of light. When these particles interact with the Earth's atmosphere or human bodies, they can cause damage to cells and DNA, leading to potential health risks. Ultraviolet rays, infrared rays, and radio waves have lower energy levels and are generally less harmful to living organisms.
