What are examples 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 are the 3 different 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.
What does diffusion mean in AP Human Geography?
Diffusion: The process of spread of a feature or trend from one place to another over time. Relocation diffusion: The spread of an idea through physical movement of people from one place to another.

How is diffusion important in geography?
The Cultural Geography Tradition of Diffusion Research The spread of a phenomenon, idea, or technique throughout a population or region incorporates basic geographic elements of distance, direction, and spatial variation, and thus forms a valid field of geographic interest.
What is called diffusion?
Diffusion is defined as the movement of individual molecules of a substance through a semipermeable barrier from an area of higher concentration to an area of lower concentration (34).
What are two types of diffusion?
Diffusion can be divided into two main types, namely, simple diffusion and facilitated diffusion.
How does diffusion occur?
Diffusion happens when a substance moves from an area of high concentration to an area of low concentration. Gases and liquids are often the particles that undergo diffusion because their particles move randomly and quickly. Diffusion is a very important process for living things in our world today.
What is diffusion short?
diffusion, process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration. A familiar example is the perfume of a flower that quickly permeates the still air of a room.
What is diffusion in living environment?
Both living and nonliving systems experience the process of diffusion. In living systems, diffusion is responsible for the movement of a large number of substances, such as gases and small uncharged molecules, into and out of cells.
What diffusion means?
Diffusion is defined as the movement of individual molecules of a substance through a semipermeable barrier from an area of higher concentration to an area of lower concentration (34).
What is diffusion explain?
diffusion, process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration. A familiar example is the perfume of a flower that quickly permeates the still air of a room. ion diffusion across a semipermeable membrane.
What is diffusion class9?
The process of movement of a substance (solid, liquid, or gas) from the region of higher concentration to the region of lower concentration so as to spread uniformly is called diffusion.
What is diffusion class 12th?
Diffusion is the process where gaseous atoms and molecules are moved from regions of comparatively high concentration to regions of comparatively low concentration. Diffusion of gas is inversely proportional to the molecular weight of the gases.
What causes diffusion?
The kinetic energy of the molecules results in random motion, causing diffusion. In simple diffusion, this process proceeds without the aid of a transport protein. It is the random motion of the molecules that causes them to move from an area of high concentration to an area with a lower concentration.
What is diffusion property?
Diffusion is a property of substances in water; substances in water tend to move from an area of high concentration to an area of low concentration. Blood flows by one side of a semi-permeable membrane, and a dialysate, or special dialysis fluid, flows by the opposite side.
What is diffusion short answer?
“Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration down the concentration gradient.”
Which is the best definition of diffusion?
Diffusion can be defined as the movement of molecules from an area of their higher concentration to an area of their lower concentration. So, the correct answer is 'Movement of molecules from an area of their higher concentration to an area of their lower concentration'.
What is diffusion in simple sentence?
Definition of Diffusion. spreading something from one place to another. Examples of Diffusion in a sentence. 1. Diffusion of the lemon and lime in the air caused a citrusy aroma to move throughout the house.
What is diffusion very short question?
Diffusion is the process of movement of molecules under a concentration gradient. It is an important process occurring in all living beings. Diffusion helps in the movement of substances in and out of the cells.
What is diffusion explanation?
diffusion, process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration. A familiar example is the perfume of a flower that quickly permeates the still air of a room.
What is diffusion easy words?
1 : the act of spreading or allowing to spread freely. 2 : the mixing of particles of liquids or gases so that they move from a region of high concentration to one of lower concentration. diffusion.
What is the importance 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 diffusion give two examples?
Perfume is sprayed in one part of a room, yet soon it diffuses so that you can smell it everywhere. A drop of food coloring diffuses throughout the water in a glass so that, eventually, the entire glass will be colored.
What is true diffusion?
Diffusion is a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration. The material that diffuses could be a solid, liquid or gas. Similarly, the medium in which diffusion occurs could also be in one of the three physical states.
Who discovered diffusion?
Thomas Graham In modern science, the first systematic experimental study of diffusion was performed by Thomas Graham.
