What specific data source allows scientists to create a calibrated crater production function in years for the Moon?
Answer
Radiometric dating of lunar rocks returned by the Apollo missions.
The ability to convert a crater count into a precise age relies on radiometric dating of returned materials, specifically the lunar rocks brought back by the Apollo missions, which provide absolute, laboratory-verified ages.
