Which consequence results when lava with high volatile content?

💡 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.
