Which process limits lava flow distance over low slopes?

A)Radiative heat transfer dominates surface losses

B)Viscosity decreases with temperature fall✓

C)Convection efficiently cools lava interiors

D)Internal friction stabilizes laminar flow

💡 Explanation

Decreasing lava temperature increases its viscosity which arrests flow, because viscous dissipation converts kinetic energy into heat rather than sustaining forward momentum, therefore flow stops rather than propagating onwards due to radiative cooling alone.
