Question

Quizplus · Accepted Answer

Radioactive carbon dating was not directly used to determine the amount of calcium present or as a standard amount for a mineral in the soil. However, it was used to determine the age of the calcium deposits, which helped establish the rate of deposition of calcium into the atmosphere. By knowing the rate of deposition, researchers could then calculate the amount of atmospheric calcium that was being added over time.
