Imagine the Earth is like a giant birthday cake, and we want to know when it was baked. Scientists use special kinds of clocks in rocks, called radiometric clocks, which work by counting how many times tiny particles have changed over time. These clocks tell us that the Earth is about 4.6 billion years old, like a really long birthday party!
Examples
- A rock acts like a clock, scientists use how much it has changed to know its age.
