What is an example of diffusion in human 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.

Common Cultural Diffusions For example, jazz started as a blend of the music of Africa and the Caribbean. Southern cities in the United States, especially border towns, have signs in both English and Spanish. The popularity of sushi, a traditional Japanese dish, shows diffusion of Japanese cuisine.
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 are the types of diffusion?
Diffusion can be classified into two main types: Simple diffusion and facilitated diffusion.
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 is diffusion example?
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 diffusion 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 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 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 in history?
Page 1. A World History Lexicon. Diffusion: the spread of ideas, languages and technologies from one area to another. Trade and human migration often lead to diffusion. The spread of Islam to South Asia or Buddhism to East Asia are examples of diffusion.
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 are three examples diffusion?
You can smell perfume because it diffuses into the air and makes its way into your nose. 2. Cigarette smoke diffuses into the air. 3. A few crystals of potassium permanganate in water will diffuse and turn the water purple.
What is cultural diffusion and examples?
Cultural-diffusion definition The definition of cultural diffusion is the spread of the beliefs and social activities of one culture to different ethnicities, religions, nationalities, etc. An example of cultural diffusion is the tradition of the German Christmas pickle becoming popular in the United States.
What is diffusion very short answer?
Diffusion is the movement of a substance from an area of high concentration to an area of lower concentration . Diffusion occurs in liquids and gases when their particles collide randomly and spread out. Diffusion is an important process for living things – it is how substances move in and out of cells.
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.
Why is diffusion important to the environment?
Diffusion is important to cells because it allows them to gain the useful substances they require to obtain energy and grow, and lets them get rid of waste products. This table shows examples of substances required by cell and associated waste products.
What is a real life example of diffusion?
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 are the example of diffusion in social change?
An example of forced diffusion would be taking Africans from their home to become slaves. An example of cultural diffusion with negative effects would be the spread of diseases, like AIDS , Bubonic Plague and Smallpox. Christianity started in Israel and has spread all over the world.
What is example of diffusion?
A tea bag immersed in a cup of hot water will diffuse into the water and change its colour. A spray of perfume or room freshener will get diffused into the air by which we can sense the odour. Sugar gets dissolved evenly and sweetens the water without having to stir it.
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 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.
Why is human diffusion important?
Diffusion is one of the body's most important processes. This is due to the fact that diffusion enables the cells to obtain nutrients and oxygen as well as expel metabolic wastes.
What is the role of diffusion?
Diffusion is important to cells because it allows them to gain the useful substances they require to obtain energy and grow, and lets them get rid of waste products.
What are two examples of diffusion in the human body?
Diffusion of oxygen and carbon dioxide gas occurs in the lungs. Diffusion of water, salts, and waste products occurs in the kidneys. Diffusion of calcium from food into cells occurs in the intestines.
What is human diffusion?
Diffusion is the process which helps in gaseous movement. In the human body, diffusion helps in gaseous exchange, water, salt and waste from our kidney. The advantage of diffusion is that it doesn't require energy for regulation, as opposed to a cell having to make proteins that pump molecules across a membrane.
Why is diffusion important in geography?
In geography, the term diffusion refers to the spread of people, things, ideas, cultural practices, disease, technology, weather, and other factors from place to place. This kind of proliferation is known as spatial diffusion.
