Final answer:
Places are primarily linked through human interaction, which includes cultural integration and the influence of the environment on human activities, affecting settlement patterns and the distribution of biomes.
Step-by-step explanation:
In the context of the theme of geography, places are linked to one another primarily through human interaction. This includes the political, economic, social, and cultural connections that people establish across places.
For instance, cultural integration and environmental determinism show how various cultural practices influence and are influenced by the environment.
Human activities such as urbanization, transportation, and economic activities affect settlement patterns and influence the size and distribution of settlements (WG.6B). Additionally, the physical environment plays a significant role, as the distribution of biomes is influenced by climate (WG.4C).
