Question

JWhich item could be dated using radiocarbon dating?


60,000-year-old mammoth bone


60,000-year-old metamorphic rock


65- million-year-old meteorite


15- million-year-old lava flow

Answer 1

Radiocarbon dating is effective for dating organic materials that are up to about 50,000 years old. In your list, the only item that could potentially be dated using radiocarbon dating is the **60,000-year-old mammoth bone**, though it is at the upper limit of the technique's effectiveness. The other items, being either inorganic or much older than the range of radiocarbon dating, cannot be dated this way.
