    Deep inside Earth, between the molten iron core and the thin crust at the surface, there is a solid body of rock called the mantle. When rock from the mantle melts. Volcanoes are natural features of the Earth's lanscape. Volcanoes form from the natural internal forces acting inside the Earth. Mos volcanoes. Volcanoes are formed when magma from within the Earth's upper mantle works its way to the surface. At the surface, it erupts to form lava flows and ash deposits .

    There are several different causes for a volcano to erupt which all Volcanoes are formed by eruptions of lava and ash when magma rises. Inside the earth's core there is a red-hot liquid rock, called magma. Volcanoes are evidence of the powerful forces at work inside the Earth. So what causes them?.

    What Causes a Volcano to Erupt, and How Do Scientists Predict and so the excess water separates from the magma in the form of bubbles. The addition of this sediment and seawater creates andesitic lava and more violent eruptions containing ash. These volcanoes form classic cone shapes. These volcanic areas usually form mountains built from the many layers of rock, ash or other material that collect around them. Volcanoes can be active, dormant . Volcanoes also form when plates move apart. Magma rises up and erupts on the surface as lava where the plates separate, for example, along the Mid Atlantic.
