The action that is an example of periodization is "Dividing China's history based on which dynasty ruled the country."
When we are studying history, the term periodization means that we split historical time to better study those periods. Periodization is a process that helps us to classify or better study the past and put several moments in pieces of blocks for clarity purposes. These periods of time give us a better chance to understand the characteristics, moments, characters, dates and events of each time. That is why the action that is an example of periodization is "Dividing China's history based on which dynasty ruled the country."
Periodization is the categorizing the past in blocks of time for the study and analysis of the history and to understand the current and historical processes. Since history is continuous, no system of periodization is perfect and without periodization, the past is just scattered events. The period labels in history are not permanent, they are constantly challenged as discoveries happen and historical events come into the light.
