Question

this method of dating ancient events and structures (such as fossils or rocks) was developed first and is used to place things in a sequential order.
○ fossil formation
○ relative dating
○ absolute dating
○ speed dating

Explanation:

The question describes a dating method for ancient events/structures that places items in sequential order. Fossil formation is the process of fossil creation, not dating. Absolute dating gives specific ages, not just sequence. Speed dating is unrelated. Relative dating is the method that establishes the relative order of events/objects without exact dates.

Answer:

B. Relative Dating
