Most people think that a volcano is a large mountain, which spews hot gases, lava, and explodes pyroclastic materials. That is not entirely true.

There are also volcanoes, and there are super volcanoes. Super volcanoes are very large volcanoes, and you might be surprised at what they look like. The list below has the biggest super volcanoes in the world.
