What are the four different types of spatial diffusion?

Types of spatial diffusion: (a) expansion diffusion, (b) relocation diffusion, (c) contagious diffusion, and (d) hierarchical diffusion (Cliff et al. 1981). This classification of spatial diffusion into four basic types, is a starting point to describing the form which this process takes.

Which statement is an example of spatial diffusion?

Recall that expansion diffusion is defined as that group of spreading phenomenon that has a source and diffuses outwards from the source. The spread of a fire, or pollution being emitted from a point source are examples of this type of spatial diffusion.

What are the barriers of spatial diffusion?

Local factors that act as barriers to the diffusion process are of three types: Physical barriers that block or slow down the diffusion. They are physical properties of space such as the topography or the land cover. Cultural barriers can influence the diffusion of an innovation that spreads from individual acceptance.

What are the three forms of expansion diffusion?

Stimulus, contagious, and hierarchical diffusion are all kinds of expansion diffusion. Expansion diffusion is when innovations spread to new places while staying strong in their original locations.

How can social barriers affect cultural diffusion?

Social barrier effects consist of characteristics that differentiate human groups and potentially limit interaction between them, thus inhibiting the spread of culture. Examples include language, religion, race and ethnicity, and a history of conflict between specific cultural communities.

What are the 3 characteristics of diffusion?

Factors that Affect Diffusion. Diffusion is affected by temperature, area of interaction, steepness of the concentration gradient and particle size.

What are three examples of diffusion?

Example of diffusion

  • The smell of perfumes/Incense Sticks.
  • Opening the Soda/Cold Drinks bottle and the CO2 diffuses in the air.
  • Dipping the tea bags in hot water will diffuse the tea in hot water.
  • Small dust particles or smoke diffuse into the air and cause air pollution.
