1. A. The point where the transfer of freight from one form of transportation to another takes place. An example would be the ports at Inside Passage.
B. The point where the separation of a shipment into smaller amounts for easier shipping to customers takes place. The ports along the Inside Passage are examples where this takes place.
C. A large sealed, metal box used to ship finished products; can be moved interchangeably by ship, train, and truck. An example of this is Seattle's container port.
D. Transportation system using two or more integrated forms of transport. Again, Seattle's container port is a good example.
E. Pass: A continuous gap through a mountain range. For example the Rogers Pass.

2. They look for gradually sloping valleys, and passes through mountain ranges. The topography of the Western Cordillera is very rugged, therefore land transport along with air transport is difficult. The most common form is water. The Panama Canal and Inside Passage are good examples of highly used passageways.

3. Vancouver, San Fran, and LA, are all gateway cities. They are the main centres of trade with the Orient, as well as with western South America. These ports link North America to one third of the world's population across the Pacific Ocean.

4. There are only 5 crossings of the Canadian Rockies. This points to the idea that the area is very rugged, filled with mountains, and valleys. Settlement is very difficult because since transport is difficult, getting there through limited passages makes it very difficult.

5. The Panama Canal made it possible to ship goods from eastern North America to the West Coast via water transport. Large amounts of North America's foreign trade now flows through western ports.

6. Ferry services that travel through Vancouver Island and the mainland of Canada and the US use these waters. Too many boats going up and down can cause conjestion. Fishing vessels must make their way through the conjestion. It is feared that there will be many accidents if precautions are not taken. The international movement of vessels make these regulations difficult to enforce.

7. In areas where they are travelling along next to a slope, snow sheds are built, and tunnels directly through the mountain are built.
