Question

which object would a geologist date using carbon - 14 dating?
○ a fossil of a dinosaur that existed 200 million years ago
○ a woolly mammoth fossil that existed 15,000 years ago
○ an ancient volcanic rock that is 100,000 million years old
○ an igneous rock that is 95,000 years old

Explanation:

Carbon - 14 dating is used for organic materials that are within a certain age range (up to about 50,000 - 60,000 years old). Dinosaurs are too old (200 million years) for carbon - 14 dating. Volcanic and igneous rocks are inorganic and not suitable for carbon - 14 dating. Woolly mammoth fossils (15,000 years ago) are organic and within the carbon - 14 dating range.

Answer:

a woolly mammoth fossil that existed 15,000 years ago
