Answer:
Population density.
Explanation:
Population density is a statistical data that allows graphing the number of people living in a given territory, dividing the number of inhabitants of that territory by its size, usually in square kilometers or square miles.
Thus, the more the population increases in a territory, the more its population density will increase. An example of territories with a high population density is Hong Kong, with about 7,000 inhabitants per square kilometer, while an example of a nation with a low population density is Canada, with 4 inhabitants per square kilometer.

Tephra deposits take many forms and shape, and their composition doesn't really matter either. The only thing that defines a tephra really is that it was ejected from the mouth of a volcano and fell on the ground where it remained intact (not merged with something else).
So, forms of tephra could be big boulders landing on the volcano's side or ashes that travel around the globe to land on the other side of the planet.
