The Atomic Clock: Radiometric Dating Explained

Unlike relative dating methods, radiometric techniques give geologists and paleontologists something far more powerful: actual numbers. Radiometric dating explained is the science of using the predictable decay rates of...

Questions: 20 | Attempts: 35 | Last updated: Mar 3, 2026

Sample Question 1
What is the primary goal of determining the "absolute age" of a rock or fossil?

To find the specific age of a sample in years

To see if it is older than a nearby rock

To determine the color of the sample

To find where the sample was buried

To count the number of layers

Sample Question 2
In the process of radiometric dating explained to students, what are isotopes?

Atoms of the same element with different numbers of neutrons

Tiny pieces of ancient bone

A type of rock found in volcanoes

The energy released by a star

A tool used to dig up fossils

Sample Question 3
When having radiometric dating explained, what does the term "half-life" represent?

The time it takes for 50% of the parent isotope to decay

Half the age of the entire Earth

The time it takes for a fossil to turn to stone

The length of a dinosaur's life

The time it takes for a rock to melt
