  • 2. 

    The core of the sun is 27 million degrees.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The core of the sun is extremely hot, with temperatures reaching up to 27 million degrees. This high temperature is necessary for the nuclear fusion reactions that occur in the core, where hydrogen atoms combine to form helium and release enormous amounts of energy. The intense heat and pressure at the core are what sustain the sun's energy output, making it the powerhouse of our solar system.

    The sun is not the largest star in our solar system.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement is false because the sun is actually the largest star in our solar system. It is much larger than any other celestial body in our solar system, including the planets. The sun's immense size and mass allow it to exert a gravitational force that keeps all the planets in orbit around it.

    The visable part of the sun is...

    • 15,000 degress F

    • 10,000 degrees F

    • 8,000 degrees F

    Correct Answer
    A. 10,000 degrees F
    Explanation
    The visible part of the sun is estimated to have a temperature of around 10,000 degrees Fahrenheit. This temperature is based on scientific measurements and observations. The sun's surface, known as the photosphere, emits light and heat that we can see and feel on Earth. This temperature is incredibly hot and is responsible for the sun's intense brightness.
