Question

(Multiple questions) Which is not an assumption that is needed if radiometric dating is to be an accurate measure of the age of an object?

A.) Half-lives can change over time.
B.) The speed of light is a constant.
C.) The amount of material being measured is constant.
D.) All of these.


Another method of dating that supports radiometric dating is
A.) tree rings
B.) ice cores
C.) coral growth
D.) all of these
30 points (i think) if you get them both :DD

Answer 1

Question 1 and question 2 are both A

Answer 2

Answer: Question #1: A

Question #2: A

Explanation: Question #1: The constant speed of light has nothing to do with radiometric dating nor the continual material being measured.

Question 2: Tree rings may be another dating method because trees develop more rings as the radioactive material decays over time.
