Radiometric dating (often called radioactive dating) is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they formed.his scheme is used to date old igneous and metamorphic rocks, and has also been used to date lunar samples. Closure temperatures are so high that they are not a concern. Rubidium-strontium dating is not as precise as the uranium-lead method, with errors of 30 to 50 million years for a 3-billion-year-old sample.
Using this method, we arrive at an age for Earth of approximately 6,000 years. Itâs important to realize that the Bible nowhere explicitly states the age of the earthâthis is a calculated number. Another method of determining the age of the earth is to use resources such as radiometric (carbon) dating, geologic cycles, and so forth. By comparing different methods, and seeing if they align, scientists attempt to determine how old the planet is. This is the method used to arrive at an age for Earth of about 4 to 5 billion years. Itâs important to realize that there is no means to directly measure the age of the earthâthis is a calculated number. Both of these methods of determining the age of the earth have potential drawbacks.
