Question

what can scientists learn from the rate at which radioactive elements decay?. A: a rock's actual, or absolute, age. B: the raletice age of rock layers. C: where one soil horizon ends and the next begins. D: the difference between molds and casts. Please help me! :)

Answer 1

From the rate at which radioactive elements decay, the rock's actual, or absolute age can be determined. Using the half-life of the material, we can calculate using first-degree order equation the age of the rock. The ratio of the original substance to the remaining substance is determined through the half-life.
