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.
