  • What form of ionizing radiation can penetrate deeply into body tissue?
    Gamma radiation can penetrate deeply into body tissue due to its high energy and high penetrating power.
  • Which is the most accurate way of determining the age of a fossil?
    Radiometric dating is the most accurate way of determining the age of a fossil.
  • Which method gives the actual age of a fossil in years?
    Radiometric dating gives the actual age of a fossil in years.
  • Which type of rock and fossil dating gives the precise age of the rock or fossil?
    Absolute dating, such as radiometric dating, gives the precise age of the rock or fossil.
  • How can we determine the age of fossils?
    The age of fossils can be determined using radiometric dating techniques.
  • How do scientists determine the actual age of fossils?
    Scientists determine the actual age of fossils using radiometric dating methods.
  • How do we know the age of fossils?
    We know the age of fossils through radiometric dating, which measures the decay of radioactive isotopes.
  • What method is used to determine the exact age of a rock or fossil?
    Radiometric dating is used to determine the exact age of a rock or fossil.
  • Earth is approximately 4.6 billion years old. How do scientists determine this?
    Scientists determine Earth's age using radiometric dating of the oldest rocks and meteorites.
  • What method is used to determine the age of fossils?
    Radiometric dating is used to determine the age of fossils.
  • What method is used to determine the specific age of a rock or fossil?
    Radiometric dating is used to determine the specific age of a rock or fossil.
  • What is the most accurate method used to measure the age of a fossil?
    Radiometric dating is the most accurate method used to measure the age of a fossil.
  • Which line on the graph represents the radioactive decay of an isotope?
    The line that shows a consistent exponential decrease over time represents the radioactive decay of an isotope.
  • Which event occurred approximately 4.6 billion years ago?
    The formation of Earth occurred approximately 4.6 billion years ago.
