Which outcome significantly reduces slope stability when groundwater interacts with phyllite?

💡 Explanation

Reduced stability rises from decreased cohesion because of the dissolution of minerals via hydrolysis, increasing pore water pressure therefore decreasing effective stress; rather than dilation or permeability changes, the primary cause is loss of mineral binding.

• Which outcome promotes stack collapse during storm surges?
• Which outcome occurs when unconsolidated pyroclastic materials saturate?
• Which risk greatly increases after pyroclastic flows deposit material onto a watershed?
• Which large-scale outcome results because deflation surpasses deposition in a coastal dune system?
• Which ecological effect results from the artificial upwelling induced by deep ocean nutrient pipes?
• Which large-scale climate effect is mitigated by the formation of oceanic gyres concentrating floating plastics?
