Which consequence results when a lava flow encounters cryospheric permafrost?

💡 Explanation

A lava flow's thermal energy causes rapid melting resulting in a jokulhaup flood because meltwater accumulates under the ice, which overcomes ice dam strength with hydrostatic pressure; therefore a flood occurs rather than slower glacial melt or unrelated geological processes.
