1. The half-life of carbon-14 is 5730 years. A sample is found to have one-eighth the original amount of carbon-14 in it. How old is the sample? 5730 years, 716 years, 45800 years, 17200 years 2. Why wouldn't you use carbon-14 dating on a piece of shell that was estimated to be 1 million years old? Sea shells do not have radioisotopes, carbon dating is only useful on plants, uranium dating is better for items older than 1/2 million years,...
