b) the relative age of rock layers

d) where one soil horizon ends and the next begins
HELP! MEH!

Answer 1

the answer is C

Step-by-step explanation:

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 cancalculate 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.
