Diffusion Concepts and Examples

The video explores the concept of diffusion in human geography, focusing on expansion and relocation diffusion. It explains the role of hearths as origin points and discusses different types of diffusion: hierarchical, contagious, and stimulus. Hierarchical diffusion is a top-down approach, contagious diffusion spreads rapidly without barriers, and stimulus diffusion involves adaptation to new cultures. The video emphasizes the importance of understanding these concepts for AP Human Geography students.

What is the role of a hearth in the concept of diffusion?

• It is a barrier to the spread of ideas.

• It is a method of spreading ideas.

• It is the origin point where an idea starts.

• It is the final destination of an idea.

In relocation diffusion, what happens to the hearth?

• It spreads to multiple locations.

• It becomes stronger.

• It weakens or may even disappear.

• It remains unchanged.

How does expansion diffusion differ from relocation diffusion?

• Expansion diffusion does not involve the spread of ideas.

• The hearth weakens in expansion diffusion.

• The hearth remains strong in expansion diffusion.

• Expansion diffusion involves physical movement.

What is a characteristic of hierarchical diffusion?

• It spreads ideas from the bottom up.

• It involves a random spread of ideas.

• It follows a top-down approach.

• It is restricted to rural areas.

Which of the following best describes contagious diffusion?

• It requires a top-down approach.

• It is limited to urban areas.

• It spreads rapidly and widely without barriers.

• It spreads slowly and selectively.

What is an example of contagious diffusion?

• A cultural practice moving with migrants.

• A new technology adopted by a company.

• A viral video spreading online.

• A fashion trend starting in a city.

What is a key difference between hierarchical and contagious diffusion?

• Contagious diffusion requires a top-down approach.

• Contagious diffusion is restricted to urban areas.

• Hierarchical diffusion is slower than contagious diffusion.

• Hierarchical diffusion follows a top-down approach, while contagious diffusion spreads widely.

In stimulus diffusion, what happens to the original idea?

• It is rejected by new cultures.

• It remains unchanged.

• It is completely replaced.

• It is adapted to fit different cultures.

Which of the following is an example of stimulus diffusion?

• A cultural practice moving with migrants.

• A new fashion trend in a city.

• A fast-food chain adapting its menu in different countries.

• A viral tweet.

How does stimulus diffusion affect the original idea?

• It completely replaces the original idea.

• It alters the original idea to fit new contexts.

• It weakens the original idea.

• It strengthens the original idea.
