BIOLOGY - Carbon-14 is a radioisotope of carbon that has a half-life of about 5,730 years. A geologist is using carbon-14 dating on charcoal samples to find the age of ancient forest fires. Match the approximate age to each charcoal sample in the following two questions. Charcoal Sample #1 has 50% of its carbon-14 remaining.
What is the approximate age of Charcoal Sample #1?
Group of answer choices:
A: 12000 years old
B: 3000 years old
C: 6000 years old
D: 18000 years old



Charcoal Sample #2 has 6% of its carbon-14 remaining.

What is the approximate age of Charcoal Sample #2?
Group of answer choices
A: 18000 years old
B: 6000 years old
C: 24000 years old
D: 12000 years old
