WebVolcanoes often form in the areas where tectonic plates make contact. The friction created by the movement between two plates can melt solid rock in the mantle and turn it into magma. This hot, molten rock creates great pressure, and over time, it finds its way up to the surface of the crust through fractures. http://www.actforlibraries.org/how-the-cascade-mountains-were-created/

WebVolcanoes are vents, or openings in Earth's crust, that release ash, gases and steam, and hot liquid rock called lava. When the lava cools and hardens, it forms into the cone-shaped mountain we think of as a volcano. Most of the world's volcanoes are found around the edges of tectonic plates, both on land and in the oceans. WebThe caldera may have formed by collapse after a large volume of andesite was erupted from vents along the caldera rim. The distribution of late Pleistocene vents, mostly concentrated along the rim, suggests that ring faults already existed when most of the andesite erupted. No single large eruption has been related to caldera formation.

This process is called subduction and creates distinctive types of volcanoes depending on the setting: ocean-ocean subduction produces an island-arc volcano.
