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. Over time as the volcano continues to erupt, it will get bigger and bigger.
Volcanoes are formed when the heat and pressure changes the rock to melt which forms liquid magma. Magma is then forced to the surface because it is less dense. Most volcanoes are found near subduction zones and mid-ocean ridges.
