Which type of volcanic eruption is characterized by highly viscous, silica-rich lava that plugs the vent, leading to violent explosions and glowing avalanches or pyroclastic flows?

💡 Solution & Explanation

Pelean eruptions are characterized by highly viscous silica-rich magma that solidifies into domes and plugs vents, resulting in violent explosions and destructive pyroclastic flows. Conversely, Hawaiian eruptions involve fluid, basaltic lava flows with minimal explosive activity. Physical geography questions frequently classify volcanic eruption types based on lava viscosity and explosiveness.
