Question
What is absolute dating of rocks and give one example
Answers
GPT 3.5
Absolute dating of rocks is a method that uses radioactive decay or other known rates of geological processes to determine the age of rocks or geological events. It provides a numerical value or age for rocks or events, allowing for a more precise understanding of Earth's history.
One example of absolute dating is radiometric dating, which uses the decay of radioactive isotopes to determine the age of a rock sample. For instance, the decay of uranium-238 to lead-206 has a known half-life of about 4.5 billion years. By measuring the relative amounts of uranium and lead in a rock sample, scientists can calculate the age of the rock.
