Aging a rock based upon its position in earths crust is known as
-
relative dating
-
blind dating
-
radiometric dating
-
casual dating
A
Correct answer
Explanation
Relative dating determines the age of a rock or fossil by comparing its position in the earth's crust to other layers. It's based on the principle that deeper layers are typically older than those above them. The humorous options (blind dating, casual dating) are obviously incorrect, and radiometric dating uses radioactive decay, not position. Note: there is a typo in 'earths' in the question.
