← GeographyWhich consequence results when lava with high volatile content?
A)Forms flood basalts at effusive vents
B)Generates substantial pyroclastic material✓
C)Creates pillow basalts upon ocean entry
D)Results in smooth, ropy pahoehoe surfaces
💡 Explanation
Significant pyroclastic material is produced because rapid decompression of lava leads to explosive fragmentation via vesiculation, also known as bubble formation. Therefore, pyroclastic material, rather than effusive lava flows, dominates eruptions from gas-rich lavas.
