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.
- Buildings sitting on permafrost can cause the soil to heat thereby releasing the frozen soil as melt water with soil.
- This can cause displace of buildings in very serious cases.
