Answer:
plate boundaries
Explanation:
Volcanoes and earthquakes are most likely to form along plate boundaries.
Earthquakes:
An earthquake is generated when two plates move relative to each other. The earthquake itself, is the movement felt on the surface caused by the movement of the tectonic plates at their boundaries. There are a few different types of plate boundaries, NOAA does a great job giving a brief description of each here:

To determine the relative age of different rocks, geologists start with the assumption that unless something has happened, in a sequence of sedimentary rock layers, the newer rock layers will be on top of older ones. This is called the Rule of Superposition. ... With absolute age dating, you get a real age in actual years
