  • 2. 

    Of Jupiter's major moons, which one most likely has life?

    • Io

    • Europa

    • Ganymede

    • Callisto

    Correct Answer
    A. Europa
    Explanation
    Europa is believed to be the most likely moon of Jupiter to have life. This is because it has a subsurface ocean of liquid water, which is considered a key ingredient for the possibility of life. The ocean is kept warm by tidal forces from Jupiter's gravity, and it is thought to have a rocky seafloor that could provide the necessary chemical reactions for life to exist. Additionally, Europa has a thin icy crust that may protect the ocean from harmful radiation. These factors make Europa a promising candidate for the presence of life in our solar system.

    Explanation

    • Mars

    • Earth

    • Mercury

    • Venus

    Correct Answer
    A. Mars
    Explanation
    Mars has the largest canyon and mountains among the inner planets. This is because Mars is known for its enormous canyon called Valles Marineris, which is about 4,000 kilometers long and up to 7 kilometers deep. Additionally, Mars has the highest mountain in the solar system called Olympus Mons, which stands at a height of about 22 kilometers. Earth, Mercury, and Venus also have canyons and mountains, but they are not as large or impressive as those found on Mars.
