How do volcanoes form. Get the world’s most fascinating discoveries delivered straight to your inbox. 75% of the world’s volcanos are on the “Ring of Fire” – a ring around the Pacific Ocean at the junction of several tectonic plates. Volcanoes are vents, or openings in Earth's crust, that release ash, gases and steam, and hot liquid rock called lava. This post delves into the fascinating journey of how volcanoes come into existence. Volcanoes erupt because of the way heat moves beneath Earth ’s surface. Learn how volcanoes form, erupt, and grow from magma, lava, and tephra. Via a “hot spot” – in this spot the magma is unusually hot and breaks through the crust without the help of a crack. Most of the world's volcanoes are found around the edges of tectonic plates, both on land and in the oceans. 6 days ago ยท Credit: Mike Doukas, USGS These volcanic areas usually form mountains built from the many layers of rock, ash or other material that collect around them. Volcanoes are also found within lithospheric plates away from plate boundaries. wnu ftcq5m2 yogj2 wx v0c qfy gcd b6z46 zn ytjd0v
