Which risk increases as a coastal lahar increases momentum?

💡 Explanation

Hydraulic plucking increases with lahar momentum because increased force overcomes the substrate's shear strength, triggering debris entrainment. Therefore, terrace erosion increases rather than sediment settling because high flows encourage greater competence.

• Which climatic consequence results when increased glacial meltwater flow amplifies coastal stream discharge?
• Which long-term consequence occurs in temperate grasslands when excessive topsoil erosion exposes nearby loess?
• Which hazard increases when overlying clay erodes above karst?
• Which outcome occurs when a volcanic eruption's viscous lava flow enters the ocean at a subglacial boundary?
• Which outcome occurs when persistent atmospheric high-pressure systems block coastal upwelling currents?
• Which outcome occurs when prolonged atmospheric blocking disrupts zonal wind streams?
