Interesting Facts about VolcanoesVolcanoes are openings in the Earth’s surface. When they are active they can let ash, gas and hot magma escape in sometimes violent and spectacular eruptions. The word volcano originally comes from the name of the Roman god of fire, Vulcan. Volcanoes are usually located where tectonic plates meet.What is a volcano?Introduction to volcanoes The earth's mountains, plains, plateaus, soils, rocks, etc. as we see it today is believed to have gone through many phases, with about 80% of it being carved out by the action of volcanoes. A volcano is simply a rapture (opening or vent) on the earth's surface (crust) through which molten magma (extremely hot mixture of gases, lava, ash and other burning substances) escape on to the earth's surface. How do Volcanoes look like? A volcano looks like a mountain, although they are two different things.A mountain is a large natural rise of the earth's surface, more like a giant heap of sand.

'Active' means there's regular activity, 'dormant' means there's been recent activity but that it's currently quiet and 'extinct', meaning it's been so long since the last eruption that it's unlikely to ever erupt again. 7. 8. 9. 10. 11.
