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 is diffusion 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 are the 4 types of diffusion?
Expansion Diffusion
- Contagious Diffusion.
- Hierarchical Diffusion.
- Stimulus Diffusion.
What is meant by term 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 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.
What is cultural diffusion in geography?
-A +A. Cultural diffusion is the spreading out and merging of pieces from different cultures. These different cultures all have many diverse types of food, clothing and even languages that people love and enjoy every day.
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.
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 GCSE?
Diffusion is the spreading out of the particles of any substance in solution, or particles of a gas, resulting in a net movement of particles from an area of higher concentration to an area of lower concentration. This means: Particles in a solution or a gas are always moving about randomly.
What is the process of diffusion?
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 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 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 is a type of diffusion?
The two main types of diffusion are passive diffusion and facilitated diffusion. The two main types of osmosis are regular osmosis and chemiosmosis.
How do you explain diffusion to a child?

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.”
What is diffusion in simple 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 diffusion in your own words?
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 osmosis and diffusion?
Osmosis is the movement of solvent particles from a solution that is diluted to a more concentrated one. In contrast, diffusion is the movement of particles from a higher concentration region to a region of lower concentration.
What is diffusion in animals and plants?
Diffusion can occur across partialy permeable membranes, such as those surrounding cells. Therefore, diffusion is involved in the movement of important molecules into and out of cells. It is important for the uptake of substances needed by cells, and also the removal of waste products produced by the cells.
What is the diffusion short answer?
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.
What is diffusion process?
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 are 5 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 3 examples of simple diffusion?
In the cell, examples of molecules that can use simple diffusion to travel in and out of the cell membrane are water, oxygen, carbon dioxide, ethanol and urea. They pass directly through the cell membrane without energy along the concentration gradient.
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.
Which of the following is the best definition of diffusion?
So, the correct answer is 'Movement of molecules from an area of their higher concentration to an area of their lower concentration'.
What is osmosis short answer?
In biology, osmosis is the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell's partially permeable membrane.
What is plant diffusion?
“Diffusion is the process of movement of molecules from a region of higher concentration to a region of lower concentration.” Diffusion in Plants. 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 in living organisms?
