← GeographyWhich outcome results when a solidified lava flow encounters buried glacial ice?
A)Formation of a deep jökulhlaup✓
B)Creation of extensive basalt columns
C)Accelerated rate of chemical weathering
D)Development of pillow lava structures
💡 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.
