Datación por carbono

The video tutorial explains how carbon dating is used to estimate the age of organic materials like wood, seeds, or animal remains. This is done by measuring the proportion of the radioactive isotope carbon-14, which decays over time. The method allows dating of materials up to approximately 50,000 years old.

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

• To estimate the age of organic matter

• To measure the density of materials

• To determine the chemical composition of rocks

• To calculate the speed of light

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

• Glass

• Metals

• Wood

• Plastics

How does carbon-14 help in determining the age of organic materials?

• By analyzing the color of the material

• By measuring the amount of carbon-14 that has decayed

• By counting the number of carbon atoms

• By checking the temperature of the material

Why is carbon-14 considered radioactive?

• Because it is found in water

• Because it is a heavy metal

• Because it decays over time

• Because it emits light

What is the maximum age range that carbon-14 dating can effectively measure?

• 100,000 years

• 1,000,000 years

• 50,000 years

• 10,000 years
