    30 seconds
    Q.

    Rocks and sediment change as they move through the rock cycle. Which change involves turning into melting?

    answer choices

    Lava to rock

    magma to lava

    rock to magma

    rock to sediment

  • Question 4
    30 seconds
    Q.

    What must happen to a metamorphic rock before it becomes a sedimentary rock rock?

    answer choices

    It must be broken down into sediment

    It must be melted into magma

    Its minerals must dissolve in water

    It must be exposed to high temperature and pressure

    An unstable isotope breaks down and becomes stable

    A stable isotope breaks down and becomes unstable

  • Question 8
    30 seconds
    Q.

    The age of a rock sample can be determined by finding the relative amount of a parent isotope that has changed into a daughter isotope within the sample. Which property of radioactive decay allows the age of the rock to be determined in years?

    answer choices

    releases energy

    releases energy

    happens in all rocks

    happens at a set rate
