When volcanoes form, melted rock, or lava, rises from underground and produces a bulge, how does the eruption restore the Earth's equilibrium? F). Pressure is released until external air pressure is greater than internal pressure, causing the system to become stable. G).Pressure continues to build until the bulge cools and becomes solid.

H). Pressure is equalized restoring the system to a stable condition.

J). Pressure is equalized but the system remains unstable.​
