chapter 11 Flashcards
Principle of least effort
considered a guiding principle in human activities; for human geographers, refers to minimizing distances and related movements
Time-space convergence
a decreasing in the friction of distance between locations as a result of improvements in transportation and communication technologies
Innovations
introduction of new inventions or ideas, especially ones that lead to change in human behaviour or production processes
Three processes characterize the evolution of transportation systems;
- Intensification: the filling of space
- Diffusion: spread across space
- Articulation: the development of more efficient spatial structures
Water Transportation
Advantages; inexpensive, good over long distance because it offers minimal resistance to movement and waterways are often available to use at no charge
Disadvantages; slow, longer than the most direct way (circuitous), not all locations are accessible by water, topographic features, like variation in relief, or weather conditions, like freezing temperature, landlocked (country with no access to water)
Railway Transportation
Advantages; second-least expensive form of transportation, are suitable for moving bulk materials when waterways are not available
Disadvantages; local topography makes railway construction (and maintenance) expensive, if not impossible
Road Transportation
Advantages; are less expensive to build than railways, are often favoured in regional planning and related schemes, most of the internal movement, bridges often reduces road distances, Can accepte multiple form of transportation
Disadvantage; traffic
Air Transportation
Advantages; it is rapid and is usually favoured for small-bulk (great size), rapid technologie change and political influence, tourist development
Disadvantage: most expensive method, damaged to environment
Containerization
Shipping containers, the important role played by containers in facilitating economic globalization is difficult to overstate
Advantages; reduced transportation costs
key factor promoting and reflecting globalization
Technology and organizational advances in transportation
One specific consequence of such advances (Technology and organizational advances in transportation) on trade
trade has become an increasingly important part of the global economy
Trade is highly vulnerable to what
the friction of distance
unequal exchange
the former export goods to the latter at prices above their value, while the latter export goods to the former at prices below their values
world trade organization
- reduce trade barriers
- reduce trade competition
- open countries to Foreign Direct Investment (FDI)
Tariff
a tax or customs duty imposed on imports from other countries
