The geographic concept illustrated by this comparison is the concept of distance decay. Distance decay refers to the idea that as distance increases, the interaction between places decreases. In the context of diffusion, this concept is important because it helps us understand how and why certain ideas, innovations, or cultural traits spread more quickly or slowly across different regions.
Hearths are important in the journeys represented here because they denote the starting points or origins of the diffusion process. They serve as the initial source from which ideas, innovations, or cultural traits spread to other regions. The hearths in this case played a crucial role in initiating and disseminating the journeys.
Hearths are similarly important in other instances of diffusion because they represent the initial point of origin or innovation. They are the places where an idea, innovation, or cultural trait first emerged and then spread to other regions. Without identifying and understanding the hearths, it would be difficult to comprehend the process and patterns of diffusion.
