← GeographyWhich process generates a lava dome following eruption?
A)High lava viscosity prevents effusion✓
B)Pyroclastic flow creates surface tension
C)Magmatic volatiles enhance lava fluidity
D)Lava fragmentation induces surface cooling
💡 Explanation
High lava viscosity causes lava dome formation because the viscous lava cannot flow far from the vent, rather it piles up around it; therefore, the dome forms unlike fluid lavas creating shield volcanoes.
