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 occurs when persistent unidirectional winds cause significant changes in beach angle relative to headlands?
• Which process increases when permafrost melts, exposing previously frozen organic material to increased bioturbation?
• Which mechanism causes formation of placer deposits near oxbow lakes during fluvial transport?
• Which outcome increases rates of erosion in cirques?
• Which landform feature forms when longshore drift connects an island to the mainland?
• Which feedback to nutrient upwelling results when benthic bioturbation decreases?
