Which volcanic outcome increases when dissolved gases exceed solubility?

💡 Explanation

Explosive eruptions occur from high gas concentrations because bubble nucleation creates rapidly expanding bubbles; this is known as “vesiculation”. Therefore, explosive eruptions form rather than effusive flows because escaping gas accelerates magma, instead of slowly oozing out.
