Image: Blazing volcano "This is an erupting volcano, showing the
process of releasing lava and smoke. Volcanoes erupt because
heat within the Earth melts rocks and creates a substance called
magma. Magma rises and pushes through the Earths surface and the
volcano erupts. Once out of the volcano, magma is called lava.
Volcanoes are one of the landforms of the Earth" - Brix Orolfo,
