The correct answer is: A) Organic materials.<\/p>\n
Radiocarbon dating is a method for determining the age of carbon-bearing materials up to about 58,000 to 62,000 years old. It is based on the fact that radiocarbon (14C) is a radioactive isotope of carbon with a half-life of about 5,730 years. When an organism dies, it stops exchanging carbon with its environment and the amount of 14C in its remains begins to decrease at a known rate. By measuring the amount of 14C in a sample, scientists can determine how long ago the organism died.<\/p>\n
Radiocarbon dating is most commonly used to date organic materials such as wood, bone, and plant remains. It can also be used to date some inorganic materials that contain carbon, such as charcoal and soil. However, it is not suitable for dating materials that are too old or that have been contaminated with modern carbon.<\/p>\n
Rocks and minerals are not suitable for radiocarbon dating because they do not contain carbon. Pottery and metal artifacts can be dated using other methods, such as thermoluminescence dating or electron spin resonance dating.<\/p>\n","protected":false},"excerpt":{"rendered":"
