Explanations: answer key for all 10 questions

Q1: Who developed radiocarbon dating in the late 1940s?
Answer: Willard Libby
He won the 1960 Nobel Prize in Chemistry.
Q2: Radiocarbon dating works on what kind of material?
Answer: Once-living organic material
It measures decaying carbon-14.
Q3: What is the half-life of carbon-14?
Answer: About 5,730 years
It works back to about 50,000 years.
Q4: Dating by tree rings is called what?
Answer: Dendrochronology
Ring patterns match across trees.
Q5: What principle says deeper layers are usually older?
Answer: Law of superposition
It is the basis of stratigraphy.
Q6: Which method dates volcanic rock millions of years old?
Answer: Potassium-argon dating
It helped date early human fossils.
Q7: Which method can date when pottery was last heated?
Answer: Thermoluminescence
It measures trapped energy in crystals.
Q8: What is relative dating?
Answer: Putting things in order without exact years
Absolute dating gives years.
Q9: Why are coins useful for dating sites?
Answer: They often show rulers or dates
A coin gives an earliest possible date.
Q10: Why are radiocarbon dates calibrated?
Answer: Atmospheric carbon-14 varied over time
Tree rings help calibrate them.

Archaeological Dating Quiz – How Old Is It?

Archaeologists use many methods to date the past. Relative dating, such as stratigraphy and typology, puts finds in order, while absolute dating gives ages in years.

Radiocarbon dating, developed by Willard Libby, revolutionized archaeology by dating organic remains up to about 50,000 years old. Tree rings, volcanic layers and thermoluminescence extend and refine dates.

Combining methods gives the most reliable results. Calibration with tree rings and other records corrects for changes in the atmosphere, making dates more accurate.
