Which outcome results when low volatile magma's viscosity reaches a threshold?

💡 Explanation

Extensive lava flows are created by lower volatile magma because at a threshold viscosity the increased internal friction reduces potential for fragmentation causing gradual emissions rather than a violent eruption; therefore flows occur rather than pyroclastic surges if there's less volatile content.
