Question

Which of these is an example of geologic relative dating? A)Putting things in order from youngest to oldest. B)This rock is 2.67 billion years old. C)Using radioisotopes to determine the exact age of a rock.

Answer 1

A)Putting things in order from youngest to oldest.

Step-by-step explanation:

Relative dating entails the placing of events in a sequence of their occurrence based on relationships between earth materials. In order to date a rock using the techniques of relative dating, some principles are usually followed. Some of the principles of relative dating are:

• Principle of superposition
• Principle of original horizontality
• Principle of lateral continuity
• Cross-cutting principle
• Principle of fossil and fauna succession.

All of these principles helps establish succinct relationships between rock layers and what they contain. Fossils which are the preserved remains of organisms in rocks are very essential in relative dating of rocks.

Putting things in order from the youngest to the oldest is relative dating. Other options are categorized as absolute dating. In absolute dating, an exact date is affixed to a geologic event.
