Why Does Lava Come Out Of Volcanoes at Blake Bunning blog

Why Does Lava Come Out Of Volcanoes. Volcanoes erupt because of the way heat moves beneath earth’s surface. The severity of the eruption depends mostly on the composition of the magma. Some volcanic eruptions are explosive and others are not. Magma that has erupted is called lava. The explosivity of an eruption depends on the composition of the magma. Some volcanoes explode violently, destroying everything in a mile radius within minutes, while other volcanoes seep out lava so slowly that you can safely walk all around them. The first question to address is: Lava flows from a fissure near the bardarbunga volcano in iceland. Molten rock below the surface of the earth that rises in volcanic vents is known as magma, but after it erupts from a volcano it is called lava. Study how magma erupts as lava and turns into pumice or hardens to form a shield volcano spectacular fountainlike eruptions at kilauea volcano, hawaii, are followed by streams of fluid lava. Effusive eruptions are those where lava oozes out of a volcano relatively gently. If magma is thin and runny, gases. It erupts from vents, sometimes as lava, but usually the magma becomes solid within the volcanic vent, giving much more explosive eruptions. Heat is conveyed from the planet’s interior to its surface largely by convection —the transfer of heat by movement of a heated fluid. Rivers of lava can flow over the ground or move more slowly as blocky masses bulldozing along.

The severity of the eruption depends mostly on the composition of the magma. The first question to address is: Why does the magma erupt at all? Effusive eruptions are those where lava oozes out of a volcano relatively gently. Volcanoes erupt because of the way heat moves beneath earth’s surface.
