Volcanoes

A volcano is the open passage from the interior of the Earth that allows the outflow or explosion of fluid rocks and gases from the interior (mantle) to the surface of the solid crust in the form of lava. This activity leads to the creation of a mountain, which in everyday language we call a volcano. The term volcano mountains and later simply volcanoes is etymologically derived from the God of fire and metallurgy Hephaestus, as it was believed that his forge was located within them. Volcanoes are fascinating because of their beauty, but also terrifying because they can cause great destruction. Although eruptions are rare and scientists usually manage to bring them under control, they are still a huge source of danger to the people who live near them.
