    • B. 

      Momentum

    • C. 

      Dispersion

    • D. 

      Erosion

    Correct Answer
    D. Erosion
    Explanation
    Erosion refers to the process of weathered material being transported and moved by the force of gravity. This can include the movement of rocks, soil, and sediment downhill or downstream. Erosion is a natural process that is influenced by factors such as water, wind, and ice, and it plays a significant role in shaping the Earth's surface over time.

    What color is a black light bulb?

    • A. 

      Yellow

    • B. 

      Green

    • C. 

      Purple

    • D. 

      Blue

    Correct Answer
    C. Purple
    Explanation
    A black light bulb emits ultraviolet light, which is not visible to the human eye. However, certain materials, such as fluorescent substances, can absorb this ultraviolet light and re-emit it as visible light. This visible light appears to be purple in color when viewed with the naked eye. Therefore, the color of a black light bulb is purple.

    When the moon appears to block the sun, as seen from Earth, what is the event called?

    • A. 

      Lunar Eclipse

    • B. 

      Blue Moon

    • C.

    • D. 

      Solar Flare

    Correct Answer
    C. Solar Eclipse
    Explanation
    A solar eclipse occurs when the moon passes between the sun and Earth, blocking the sun's light and casting a shadow on Earth's surface. This alignment causes the moon to appear to completely or partially cover the sun, resulting in a temporary darkening of the sky. During a solar eclipse, the moon's shadow can be seen on Earth, creating a visually stunning phenomenon. Therefore, the correct answer is Solar Eclipse.

    What is a nuclear reaction in which two small atomic nuclei fuse called in scientific terms?

    • A. 

      Nuclear Fusion

    • B. 

      Fission

    • C. 

      Gravity

    • D. 

      Nebula

    Correct Answer
    A. Nuclear Fusion
    Explanation
    Nuclear fusion is a scientific term used to describe a nuclear reaction in which two small atomic nuclei merge together to form a larger nucleus. This reaction releases a tremendous amount of energy and is the process that powers the sun and other stars. Unlike nuclear fission, which involves the splitting of a large atomic nucleus into smaller parts, nuclear fusion involves the combination of smaller nuclei to form a larger one. Gravity and nebula are not scientific terms used to describe this specific type of nuclear reaction.
