1. Things that influence Spatial Diffusion

2. Make a diffusion t-chart Physical Features that AID (help) diffusion Physical Features that are barriers to (block) diffusion Directions add the 3 Aids and 3 barriers on the following slides to your chart.

3. Physical Features that AID (help) in diffusion 1.Rivers – serve as transportation routes

4. The Ship Channel

5. Large ships importing and exporting goods in the Houston Ship Channel.

6. Physical Features that AID (help) in diffusion 2. Plains – flat land allows for easy travel

7. 3. Harbors (2 types) – allow transportation and trade between foreign countries –Man-made –Natural Harbors

8. San Francisco How does the topography of San Francisco help trade? - The shape of the land creates a natural harbor.

9. Physical features that block spatial diffusion 1. Deserts – harsh travel

10. Physical features that block spatial diffusion 2. Mountains – act as a barrier, block travel

11. Physical features that block spatial diffusion 3. Ocean – too big to travel across Tasks: Give two examples of technology that allow people to overcome these 3 barriers to diffusion.

12. Divide your paper in half Left Side: Cartoon A Sketch a cartoon of daily life in a country that has no barriers to diffusion You must include evidence of physical features that aid diffusion Show people practicing at least one example of similar culture. –Example: people eating the same type of food. Right Side: Cartoon B Sketch a cartoon of daily life in a country that has each barrier to diffusion Include all physical features that are barriers to diffusion Create new examples of culture that were never able to diffuse. –Example: people wearing pants on their heads
