Which outcome primarily follows rising magma’s volatile exsolution?

💡 Explanation

An explosive eruption results because volatile exsolution rapidly expands dissolved gasses, creating extreme pressure. Therefore, explosive eruptions occur, rather than effusive flows, because bubble nucleation facilitates rapid magma degassing.
