3.4 Types of Diffusion

• What are the three types of expansion diffusion?

  Hierarchical, contagious, stimulus
• Match the type of diffusion with its mechanism:

  Relocation Diffusion ↔️ Movement of people

  Hierarchical Diffusion ↔️ Spread from large to small centers

  Contagious Diffusion ↔️ Spread through direct contact

  Stimulus Diffusion ↔️ Adaptation of an idea
• Spatial diffusion refers to the spread of ideas across geographic space.

  True
• Relocation diffusion occurs when people move from one place to another, bringing their culture, ideas, and practices
• What is the primary focus of spatial diffusion?

  Geographic space
• What are examples of barriers that can impede diffusion?

  Mountains, borders, language
• What is an example of relocation diffusion?

  Spread of a religion through migration
• Match the type of diffusion with its mechanism:

  Hierarchical Diffusion ↔️ Spreads from large to small centers

  Contagious Diffusion ↔️ Spreads through direct contact

  Stimulus Diffusion ↔️ Introduces a new idea that gets adapted
• Temporal diffusion is the spread of ideas, innovations, behaviors, or traits over time
• Physical, political, or cultural features can act as barriers or boundaries that impede the spread of a phenomenon
• What are diffusion paths in spatial diffusion?

  Specific routes of spread
• Hierarchical diffusion starts in smaller towns and spreads to larger cities.

  False
• Stimulus diffusion involves the modification of an idea as it spreads.

  True
• What is the adoption rate like during the early stage of temporal diffusion?

  Slow
• Match the type of diffusion with its definition:

  Spatial Diffusion ↔️ Spread of ideas across geographic space

  Temporal Diffusion ↔️ Spread of ideas over time
• Relocation diffusion occurs when people move from one place to another, bringing their ideas and culture
• Hierarchical diffusion spreads from large urban centers to smaller ones
• The two major types of diffusion are spatial and temporal
• What is the main focus of spatial diffusion?

  Spread across locations
• Match the type of diffusion with its example:

  Relocation Diffusion ↔️ Spread of a religion through migration

  Hierarchical Diffusion ↔️ Fashion trends starting in major cities

  Contagious Diffusion ↔️ Spread of a virus

  Stimulus Diffusion ↔️ Modification of a fast-food menu
• Distance decay refers to the decrease in influence with increasing distance from the source.


  True
• Understanding the characteristics of spatial diffusion is important for analyzing how ideas spread geographically.

  True
• Contagious diffusion spreads like a disease from person to person.


  True
• What is the definition of spatial diffusion?

  Spread across geographic space
• What is the effect of distance decay on diffusion?

  Decreased influence with distance
• What is an example of contagious diffusion?

  Spread of a social media trend
• What is the mechanism of contagious diffusion?

  Direct contact
• Arrange the stages of temporal diffusion based on adoption rate:

  1️⃣ Early Adoption (Slow)

  2️⃣ Rapid Adoption (Accelerating)

  3️⃣ Late Adoption (Leveling off)
• Innovations that are compatible, simple, and advantageous tend to diffuse more rapidly
• The spread of a religion via migration is an example of spatial diffusion
• What is diffusion in human geography?

  Spread of ideas or traits
• Contagious diffusion spreads widely from one person to another, like a disease.


  True
• What is an example of stimulus diffusion?

  Modification of a fast-food menu
• Temporal diffusion refers to the spread of ideas over time
• Contagious diffusion spreads from large urban centers to smaller ones.

  False
• Temporal diffusion is the spread of ideas, innovations, behaviors, or traits over time
• Diffusion paths shape the overall pattern of diffusion
• Hierarchical diffusion spreads from large, connected urban centers to smaller ones
• What does distance decay in spatial diffusion refer to?

  Influence decreases with distance
• Spatial diffusion focuses on the spread across locations, while temporal diffusion focuses on the spread over time.
