A. The heat from buildings melts the ice in the permafrost below and the water is then displaced.
Explanation:
- Permafrost are frozen soils in temperate and polar regions.
- For a long period of time, if the soil remains frozen due to the presence of water that remains above freezing point, permafrosts forms.
- Permafrost are usually a bane to construction works.
- When the Trans-Alaskan Pipeline was being built, accommodation was made for the permafrost in the terrain.

1-Data set 1 represents the wealthiest countries by GDP whilst the other shows wealthiest countries by GDP PER CAPITA. The reason the two sets of data differed per each list is because, lets say, United States has more GDP in total than Liechtenstein. However, the reason Liechtenstein has more GDP per capita is because it has more money proportional to the number of capitas. The US has 14.265(in trillions) but it is spread into millions of capitas, so the number shrinks.
