Which risk increases when thawing permafrost causes widespread solifluction on Arctic slopes used for pipeline construction?

💡 Explanation

When thawing permafrost causes solifluction, soil liquefies and flows downslope due to gravity, because soil cohesion decreases substantially, leading to ground instability and deformation. Therefore pipeline displacement results, rather than pipe insulation effects, corrosion, or hydrate formation which require other conditions.
