Question

which statement explains how determining the age of the remains of living things is similar to dating rocks? o organisms and rocks both contain stable and unstable elements. o organisms contain the same unstable elements as those found in rocks. o elements in rocks decay at the same rate as elements in the remains of organisms. o rocks and organisms both have gases trapped inside that are measured to determine age.

Explanation:

Radiocarbon dating of living - things and radiometric dating of rocks both rely on the presence of stable and unstable elements. The decay of unstable elements over time is used to calculate age. In living things, carbon - 14 (unstable) and carbon - 12 (stable) are involved. In rocks, various radioactive (unstable) and non - radioactive (stable) elements are considered.

Answer:

Organisms and rocks both contain stable and unstable elements.
