Expansion diffusion is the spread of a trend or idea from its origin point outwards. Crucially, in expansion diffusion, the number of adopters *increases* as the idea spreads. Think about a catchy song that starts in one city and then becomes popular everywhere, or a new farming technique that originates in one region and spreads to neighboring areas. There are different types, including hierarchical (spreading through a hierarchy of places), contagious (spreading through direct contact), and stimulus (where the underlying idea inspires a new, but related, idea).
Match the term with its definition:
| Term | Definition |
|---|---|
| 1. Hearth | A. The rapid spread of an idea through a population. |
| 2. Contagious Diffusion | B. The process where a trend spreads from one place to another. |
| 3. Expansion Diffusion | C. A place of origin or innovation. |
| 4. Hierarchical Diffusion | D. The spread of an idea from persons or nodes of authority or power to other persons or places. |
| 5. Stimulus Diffusion | E. When the spread of an idea prompts a new idea or innovation. |
