Answer:
Population distribution determines in large part the cultural landscape.
Explanation:
For example, regions with high population density tend to have a cultural landscape that is characterized by being urban, or by having many towns in a relatively small land area. In these places, culture also tends to be more dynamic, because there is more human interaction.
On the other hand, regions with low population density are characterized by a rural landscape that is sparsely populated. These areas also tend to be more culturally closed, and they are less dynamic as well, because of lesser human interaction.
