Which outcome occurs when a warming climate thaws discontinuous permafrost beneath an Arctic oil pipeline?

💡 Explanation

When permafrost thaws, differential settling occurs because the ground becomes unstable and shifts unevenly under the pipeline's weight altering pipe supports, inducing torsional stress as sections lose uniform support. Therefore, torsional stress results, rather than corrosion, embrittlement, or thermal changes which require distinctly different preconditions.
