Answer:
C. Ageing infrastructure as exceptionally expensive to maintain.
Explanation:
Near the South Nation River lies the Galop Canal, the historical predecessor to the St. Lawrence Seaway. Galop Canal ran 12 kilometers from Iroquois to Cardinal. The nature of life along the St. Lawrence banks began to change and newer, larger, locks were built to ship larger amounts of cargo from the Great Lakes.
Answer:
D. Ocean - Atmosphere - Wind - Weather
Explanation:
- The El Nino (warm) and La Nina (cool) are the opposing phases of climatic patterns in the tropical pacific ocean and take place every 3 to 7 years. Combined they are called ENSO.
- First, in the El Nino ocean temperatures in the eastern tropical pacific ocean rise above average and this leads to rainfall over Indonesia and storms in central pacific. This rising air increases the air motion and leads to dryness and high surface pressure during the La Nina phase this condition gets reversed.
- During the El Nino, the northwestern pacific tends to be warmers and the southern tier of California tends to be cooler and wetter. These surface temperatures are caused and changed by the help of trade winds. These blows from east to west along the pacific ocean.
- These phenomena thus influenced the weather along the western and the eastern pacific ocean.
The correct answer is - B. waterways that are frozen over half the year.
The people that live in areas that have extremely cold climates face numerous problems because of the very low temperatures, long-lasting ice and snow. One of the big problems is the traveling. The waterways are an effective way of transport in this areas, being without obstacles, going over large distances, relatively cheap. The problem is that for over half a year, this main transportation mean is not usable because it is frozen. While that makes it easier to get from one side of the river to another by simply walking over the ice, the people are not able to use the water for travel, thus they have to go to slower, more dangerous ways to travel.
