Dating rocks and fossils using radioisotopes
{"Image DocumentName": "Radiometric DatingScientists can use UNSTABLE atoms to determine the age of some rocks and fossils.", "Image ImageDescription": "Unstable atoms decay (release energy) at a predictable rate over time. The atoms change as they decay. Comparing the number of unchanged atoms (parent) and changed atoms (daughter), the age can be determined. The rate these atoms decay is called the half-life.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
