My answers:
1). Factors which can affect the choice of a location of a city are sources of water, landscape, climate, weather, and the availability of natural resources.
2).The St. Lawrence Seaway is important because it enables huge, oceangoing vessels to sail into the industrial and agricultural heartland of North America.
3). Methods of moving people and goods across the continent have changed over time by advances in transportation, such as transcontinental railroads, canals, and national highway systems.
4). Transportation systems crossing the continent have altered the continent by the need to cut down forests, build bridges over streams, and blast tunnels through mountains.
3). Methods of moving people and goods across the continent have changed over time by advances in transportation, such as transcontinental railroads, canals, national highway systems, and the St. Lawrence Seaway.
3. Oops! You've missed a major modern transportation method.
I agree with your other answers.
