Which mechanism increases avalanche risk along steep fjord walls during periods of heavy snowfall?

A)Isostatic rebound reduces slope stability

B)Wind loading creates unstable snow cornices✓

C)Cryoturbation weakens bedrock structure

D)Solifluction increases downslope creep rate

💡 Explanation

When heavy snowfall occurs along fjord walls, wind loading creates snow cornices as wind deposits snow on the leeward side of ridges; increased weight destabilizes the cornice, triggering avalanches. Therefore wind loading creates unstable snow cornices, rather than isostatic rebound, cryoturbation or solifluction, which are much slower processes.
