What does diffusion mean in AP Human Geography?

What does diffusion mean in AP Human Geography?

Diffusion, in the scope of geography, is the spread of people, things, ideas, cultural practices, disease, technology, weather, and. more from place to place; thus, it’s called spatial diffusion (spreads across space).

What is an example of diffusion in geography?

Expansion diffusion is when innovations spread to new places while staying strong in their original locations. For example, Islam has spread throughout the world, yet stayed strong in the Middle East, where it was founded.

What are the 4 types of diffusion?

Expansion Diffusion

• Contagious Diffusion.
• Hierarchical Diffusion.
• Stimulus Diffusion.

What is the difference between diffusion and distribution?

As nouns the difference between diffusion and distribution is that diffusion is the act of diffusing or dispersing something, or the property of being diffused or dispersed; dispersion while distribution is an act of distributing or state of being distributed.

What is an example of relocation diffusion?

An example of relocation diffusion is the spread of religions such as Christianity and Islam, to different parts of the world by persons that took these religions along with them when they moved to new locations.

What are the 6 types of diffusion?

The 6 Types of Cultural Diffusion

• Relocation Diffusion.
• Expansion Diffusion.
• Contagious Diffusion.
• Hierarchical Diffusion.
• Stimulus Diffusion.
• Maladaptive Diffusion.

What are the five types of diffusion?

Relocation, expansion, contagious, hierarchical, and stimulus diffusion.

What is an example of diffusion in society?

Cultural diffusion has to do with how the many different parts of culture are adopted by other cultures. An example of cultural diffusion would be the widespread adoption of the use of a cell phone (and often a smartphone) across many different countries and cultures.

What is the process of diffusion?

“Diffusion is the process of movement of molecules from a region of higher concentration to a region of lower concentration.” Diffusion is a very important process for photosynthesis where carbon dioxide from the stomata diffuses into the leaves and finally into the cells.

What is the importance of diffusion in respiration?

Diffusion is important for the following reasons: During the process of respiration, this process helps in diffusing the carbon dioxide gas out through the cell membrane into the blood. Diffusion also occurs in plant cells. In all green plants, water present in the soil diffuses into plants through their root hair cells.

What is the difference between dialysis and facilitation diffusion?

Facilitated diffusion is a passive movement of molecules across the cell membrane from the region of higher concentration to the region of lower concentration by means of a carrier molecule. Dialysis: It is the diffusion of solutes across a selectively permeable membrane.

What is the relationship between rate of diffusion and density?

The rate of diffusion is directly proportional to the difference in concentration of the molecules in the two regions. The rate of diffusion is directly proportional to the increase in temperature. The rate of diffusion is inversely proportional to the square root of density of the gas.
