Which process limits lava flow reach, when effusive eruption?

💡 Explanation

Lava travel plateaus because increased viscosity slows effusion; lava cools, changing viscosity and stopping flow rather than radiative transfer from surface dominating, because viscosity-driven flow reduction affects depth and rate rather than just surface temperature changes.

• Which crustal deformation results at a subduction zone?
• Which risk increases for coastal communities when locked sections of subduction zones suddenly rupture?
• Which outcome occurs when thermokarst thaw lakes expand?
• Which thermal consequence arises where oceanic crust subducts beneath continental crust?
