Strictly defined, expansion diffusion is the process of spreading something from one place to another in an ever-expanding "snowballing" process. Expansion diffusion is used to explain a variety of phenomena in numerous disciplines, from the spread of disease in medicine to the process of human settlement in the study of geography 1.

What are some real life examples of diffusion?
Some examples of diffusion that occurs in our daily life are given below. 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.
What are the types of diffusion?
Diffusion describes the spread of goods, ideas, and people between targets. Primary types of diffusion include expansion diffusion, hierarchical diffusion, contagious diffusion, stimulus diffusion, and relocation diffusion. Expansion diffusion: This diffusion originates from a central place and expands outward to other locations
What is the difference between mixing and diffusion?
mixing. - Harsha (age 7) A: Diffusion is the random wandering of things (molecules, atoms, etc.) as they are pushed to and fro by little random jiggles of their neighbors. These little random jiggles are always present- the hotter something is, the more of them there are. Diffusion can mix up different chemicals on a small scale.
Why is expansion diffusion important?
The importance of expansion diffusion is that this explains, and can thus help people better understand, numerous cultural distributions. For example, it can assist businesses in identifying how their products can spread farther, and it can help sociologists in understanding how language or music spreads.
How does expansion diffusion happen?
Relocation diffusion occurs when a person migrates from their home and shares their culture with a new location. Expansion diffusion occurs when a trend is spread from its originating place, outward. There are several forms of this type of diffusion including contagious, hierarchical, and stimulus diffusion.
What is expansion diffusion quizlet?
Expansion diffusion. The spread of an idea through a population in a way that the number of those influenced becomes continuously larger. Includes contagious, hierarchical, and stimulus diffusion.
What are the 2 types of expansion diffusion?
Expansion diffusion comes in two types: contagious and hierarchal.
What are the 4 types of expansion diffusion?
There are three types of expansion diffusion: stimulus diffusion, hierarchical diffusion, and contagious diffusion.
What are the 3 types of diffusion?
The three types of diffusion are - simple diffusion, osmosis and facilitated diffusion.(i) Simple diffusion is when ions or molecules diffuse from an area of high concentration to an area of low concentration.(ii) In osmosis, the particles moving are water molecules.More items...
What are the 4 types of diffusion in biology?
What Are the Different Types of Diffusion Across a Membrane?About Diffusion. All types of diffusion occur passively, which means that the cell does not have to expend energy. ... Simple Diffusion. ... Channel Diffusion. ... Facilitated Diffusion.
What are types of diffusion?
Diffusion can be classified into two main types: Simple diffusion and facilitated diffusion.
What are the 5 types of diffusion?
Relocation, expansion, contagious, hierarchical, and stimulus diffusion.
Is McDonald's an example of expansion diffusion?
Example of Stimulus Diffusion McDonalds still has the same 'fast food theme' and Golden arches throughout the world, but the foods and other things may change to fit the culture of the place it is in. McDonald's success also inspired a growth of competitors who used their food assembly model.
What are the 6 types of diffusion?
There are six types of cultural diffusion:Relocation Diffusion.Expansion Diffusion.Contagious Diffusion.Hierarchical Diffusion.Stimulus Diffusion.Maladaptive Diffusion.

Where does diffusion happen in the body?
The lungs are where oxygen and carbon dioxide gas diffuse. The kidneys are responsible for the diffusion of water, minerals, and waste products. In the intestines, calcium from meals diffuses into cells.
What is the process of diffusion in cells?
Diffusion is random movement of molecules but has a net direction toward regions of lower concentration in order to reach an equillibrium. Simple passive diffusion occurs when small molecules pass through the lipid bilayer of a cell membrane.
Why does diffusion happen faster at higher temperatures?
When temperature increases, the kinetic energy of the particles has increased. The increased motion of the particles causes them to diffuse faster. Therefore, at higher temperatures, the rate at which fluid particles will diffuse is faster than at lower temperatures.
Where does diffusion occur in plants?
stomataDiffusion and the leaf It diffuses through small pores called stomata. The stomata are mainly in the lower epidermis (the underneath surface) of leaves. During photosynthesis, oxygen levels inside the leaf increase. This causes oxygen to diffuse out of the leaf into the air.
