← GeographyWhich long-term consequence directly follows from pervasive solifluction near tundra oil pipelines?
A)Increased pipeline stress and buckling✓
B)Rapid metal corrosion of the pipe
C)Reduction in CO2 sequestration
D)Methane hydrate phase transition
💡 Explanation
Pipeline stress increases because seasonal thaw weakens soil support, permitting downslope soil creep via solifluction; this permanently alters pipeline loads. Therefore, buckling risk increases, rather than quicker corrosion or direct gas release from hydrates.
