This is the correct answer because NASA is a government agency in the United States that is responsible for the nation's civilian space program and for aeronautics and aerospace research. The acronym accurately reflects the organization's focus on both aeronautics (the science of flight within the Earth's atmosphere) and space exploration.

    Is the sun a star or a moon?

      A Star

    • B. 

      A Moon

    Correct Answer
    A. A Star
    Explanation
    The sun is a star because it is a massive, glowing ball of gas that produces its own light and heat through nuclear fusion. It is the closest star to Earth and is the center of our solar system. Moons, on the other hand, are natural satellites that orbit planets, and the moon specifically refers to Earth's natural satellite.

      Earth

    • C. 

      Mercury

    • D. 

      Pluto

    Correct Answer
    A. Venus
    Explanation
    Venus is the correct answer because it is the only planet in the given options that is approximately the same size as Earth. Venus has a diameter of about 12,104 kilometers, which is only slightly smaller than Earth's diameter of about 12,742 kilometers. Mercury is smaller than Earth, while Pluto is much smaller and is no longer classified as a planet.

    True or FalseMercury has no air

    • A. 

      True

    • B. 

      False

    Correct Answer
    A. True
    Explanation
    Mercury has no air because it has a very thin atmosphere consisting mostly of trace amounts of helium and hydrogen. The planet's proximity to the Sun means that the high temperatures cause any gases to escape into space. The lack of air on Mercury is due to its small size and weak gravity, which cannot hold onto gases as effectively as larger planets like Earth.

      Mercury

    • B. 

      Mars

      Venus

    • D. 

      Jupiter

    Correct Answer
    B. Mars
    Explanation
    Mars is known as the red planet because of its reddish appearance. This is due to the iron oxide (rust) on its surface, which gives it a distinctive reddish color. Additionally, Mars has a thin atmosphere that scatters sunlight in a way that makes the planet appear red when viewed from Earth.

    • D. 

      Pluto and Earth

    Correct Answer
    A. Jupiter and Uranus
    Explanation
    Jupiter and Uranus are the correct answer because they are the two planets in our solar system that have rings. Jupiter's rings are made up of small particles of rock and dust, while Uranus' rings are composed of mainly ice particles. The other options, Mars and Uranus, Pluto and Earth, and Jupiter and Neptune, are incorrect as Mars, Pluto, and Earth do not have rings, and Neptune only has a faint ring system.
