Large cracks and rifts in Antarctic ice shelves are regular occurrences driven by natural mechanical processes such as wave-induced stresses, shear deformation, and fracture mechanics.

The analysis

The retrieved papers consistently describe large rifts and cracks in Antarctic ice shelves as natural features governed by physical processes like wave-induced stresses, internal structure heterogeneity, and shear stress along ice streams. No papers refute the natural occurrence and propagation mechanisms of these rifts.
