WebMany eruptions are relatively quiescent and are characterized by the calm, nonviolent extrusion of lava flows on the earth's surface. Other eruptions, however, are highly explosive and are characterized by the violent ejection of fragmented volcanic debris, called tephra, which can extend tens of kilometers into the atmosphere above the volcano. WebOutpouring lava What is Viscosity? A measure of magma's mobility to flow. Why is temperature important? Because the hotter the magma the less vicious. It flows easier Why is gas so important?
