Question

how do geologists use relative dating? placing rocks in order from youngest to oldest to determine generic timelines placing rocks in order by minerals they contain to determine economic value. classifying rocks by different textures to see which one looks coolest. classifying rocks by different isotopes to determine their exact ages.

Explanation:

To determine the correct answer, we analyze each option:

• The purple option is incorrect as relative dating is not about economic value.
• The red option is incorrect as "looking coolest" is not a scientific method for dating rocks.
• The teal option is incorrect because classifying by isotopes is absolute dating, not relative.
• The yellow option is correct: Relative dating in geology involves placing rocks in a sequence from youngest to oldest (or vice versa) to establish a chronological order (generic timelines) without assigning exact ages.

Answer:

A. Placing rocks in order from youngest to oldest to determine generic timelines
