Question

Quizplus · Accepted Answer

The expansion of volcanic gas, specifically the sudden release of gas pressure, is mainly responsible for causing an explosive volcanic eruption. As magma rises towards the surface of the earth, the pressure on the gas within the magma decreases, causing the gas to expand and create bubbles. When the gas pressure builds up enough, it can cause an explosive eruption, which is characterized by the violent ejection of ash, rock, and gas into the air. Lava flows, the latitude at which the volcano occurs, and the age of the volcano may all play a role in the type and scale of eruption, but they are not the main cause of an explosive eruption.
