← GeographyWhich risk greatly increases where a volcanic dome's slope exceeds its angle of repose?
A)Catastrophic gravitational slope failure✓
B)Erosion due to increased precipitation
C)Magmatic inclusions within the edifice
D)Accelerated hydrothermal vent formation
💡 Explanation
Gravitational slope failure risk acutely grows due to exceeding the material's angle of repose; the increased stress enacts gravitational collapse. This powerful landslide event occurs because of destabilization, resulting in collapse, rather than processes like eruption or erosion alone.
