    The definition of "the ratio of the mass of a substance to the volume it occupies" best fits which science term?

    • A.

      Dat

    • B.

      Fault

    • C.

      Density

    • D.

    Correct Answer
    C. Density
    Explanation
    Density is defined as the ratio of the mass of a substance to the volume it occupies. It is a fundamental concept in science that helps describe how closely packed the particles of a substance are. The higher the density, the more mass there is in a given volume, indicating a denser substance. Therefore, density is the science term that best fits the given definition.

    "Energy return of a radar signal after it has hit the target" best fits which science term?

    • A.

      Radar Echo

    • B.

      Carbohydrate

    • C.

      Stratosphere

    • D.

      Ecosystem

    Correct Answer
    A. Radar Echo
    Explanation
    Radar echo refers to the energy return of a radar signal after it has hit the target. When a radar signal encounters an object, it bounces back and is detected by the radar receiver as an echo. This echo provides information about the target's location, distance, and other characteristics. The term "radar echo" specifically describes the phenomenon of the energy return of a radar signal, making it the best fit for the given description.

    Correct Answer
    D. Eclipse
    Explanation
    An eclipse refers to the obscuring from sight of one celestial body by another. It occurs when one celestial body, such as the moon, passes between another celestial body, such as the sun, and the observer, blocking the light and causing a temporary darkening or shadowing effect. This phenomenon is a result of the alignment and relative positions of the celestial bodies.

      Equator

    • D.

      Aerosol

    Correct Answer
    C. Equator
    Explanation
    The correct answer is Equator. The equator is an imaginary line that divides the Earth into the Northern Hemisphere and the Southern Hemisphere. It is located at 0 degrees latitude and is the widest part of the Earth. It is significant because it determines the climate zones on Earth and plays a role in weather patterns.
