Carbon dating

The video tutorial explains how to estimate the age of organic materials like wood, seeds, or animal remains by measuring the proportion of the radioactive isotope carbon-14. This method, known as carbon dating, relies on the decay of carbon-14 over time and can date materials up to 50,000 years old.

What is the primary purpose of using carbon-14 in scientific studies?

• To determine the chemical composition of materials

• To estimate the age of organic materials

• To identify the color of ancient artifacts

• To measure the weight of organic materials

Which of the following materials can be dated using carbon-14?

• Glass

• Wood

• Plastics

• Metals

Why is carbon-14 considered useful for dating purposes?

• It is radioactive and decays over time

• It is abundant in all materials

• It changes color over time

• It is stable and does not decay

Which isotope is used in the process of carbon dating?

• Carbon-15

• Carbon-13

• Carbon-12

• Carbon-14

What is the maximum age limit for materials that can be dated using carbon-14?

• 50,000 years

• 25,000 years

• 10,000 years

• 100,000 years
