Which outcome results when a solidified lava flow encounters buried glacial ice?

💡 Explanation

A meltwater pulse and flash flood (jökulhlaup) results because the lava flow's thermal energy causes rapid ICE MELTING under the flow; therefore a large volume of water is released, rather than causing basalt columns or other lava formations.
