Explain in detail the technique used for determining the age of rocks.

One of the primary techniques used to determine the age of rocks is radiometric dating, which relies on measuring the decay of radioactive isotopes present within the minerals of the rocks. Radiometric dating is highly useful in geology, paleontology, and evolutionary biology, as it provides accurate and precise information about the time at which a rock formed. This method is based on the principle that certain isotopes are unstable and spontaneously decay at a constant rate, known as their half-life. By measuring the ratio of the parent isotope to its stable daughter product, scientists can calculate the time that has elapsed since the rock solidified.
