WebMar 30, 2024 · Examine the diagram below. The lettered objects represent volcanoes … WebVolcanoes form where the subducting oceanic plate gets hot enough to “sweat” fluids and initiate melting. (Modified from Lillie, 2005.) Subduction zones produce volcanic arcs, curving chains of steep-sided volcanoes, for example the Aleutian Islands in Alaska.
WebVolcanoes often form along where plate tectonics make contact. The friction produced melts the Earth’s crust, creating magma. Extremely heated magma creates pressure and slowly rises to the surface through the fractures between the tectonic plates. Over time it finds its way out through a volcanic vent. WebVolcanoes that form along a mid-ocean ridge occur at a(n) diverging plate boundary. true. A pyroclastic flow typically occurs during a(n) quiet eruption. ...
