How When A Volcano Erupts. Heat is conveyed from the planet’s interior to its surface largely by convection —the transfer of heat by movement. Most volcanoes provide warnings before an eruption. Volcanoes erupt because of the way heat moves beneath earth’s surface. A volcano erupts when magma rises to the surface due to lower density and pressure, aided by the formation of gas bubbles. In many volcanoes, the magma rises up through a central tube. They can blast out clouds of hot tephra from the side or top of a volcano. The type and severity of an eruption depend. Once there's enough molten rock — called magma — and enough pressure on it, a volcanic eruption occurs. The buoyancy of the magma, the pressure from the exsolved gases in the magma and the injection of a new. Magmatic eruptions involve the rise of magma toward the surface, which normally. Magma is the name for that molten rock. How can we tell when a volcano will erupt? Explosive volcanic eruptions can be dangerous and deadly. A volcano is a spot in earth’s crust where molten rock, volcanic ash and certain types of gases escape from an underground chamber. Although there are several factors triggering a volcanic eruption, three predominate:
