A geologist has collected this data about the rock ages in a certain area. If generating a key for this data, what is the correct sequence from bottom to top?

Relative dating

Explanation:

Usually the age of formations of a rock is categorized in a geologic time scale.

There are two different types of geologic time scale;

a. Relative dating sequence

b. Absolute dating sequence

The correct sequence from bottom to top is the relative time dating. The Relative dating shows rock ages in their order of occurrence (from Bottom to Top).

These are examples of relative dating sequence:

Superposition, Crosscutting Relationships, Sequence from bottom to top, Inclusions, Faunal Succession.
