Geochronology is the science of determining the age of rocks, fossils, and sediments to build a timeline of Earth’s history. By using dating methods like radiometric dating, scientists measure the decay of radioactive isotopes to calculate the age of materials. Techniques such as uranium-lead dating and carbon-14 dating help date ancient rocks and organic materials, respectively. Geochronology is crucial for understanding geological processes, the evolution of life, and the timing of events like volcanic eruptions or the formation of mountain ranges. This field provides a window into Earth’s past, helping us understand its dynamic history and the processes shaping our planet.
