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. Volcanoes associated with subduction zones generally have steep sides and erupt ...

How does a hot spot form a chain of volcanoes? - Answers

Hotspot volcanoes are considered to have a fundamentally different origin from island arc volcanoes. The latter form over subduction zones, at converging plate boundaries. When one oceanic plate meets another, the denser plate is forced downward into a deep ocean trench. This plate, as it is subducted, releases water into the base of the over-riding plate, and this water mixes with the rock, thus changing its composition causing some rock to melt and rise. It is this that fu… Web1) What is a hotspot? A volcanic "hotspot" is an area in the upper mantle from which heat rises in a plume from deep in the Earth.

What is a hotspot and how do they affect volcanoes?

WebHotspots are the only types of volcanism not associated with subduction or rifting zones at plate boundaries; they seem totally disconnected from any plate tectonics processes, such as earthquakes. However, there are relationships between hotspots and plate tectonics. WebA hot spot is an intensely hot area in the mantle below Earth's crust. The heat that fuels the hot spot comes from very deep in the planet. This heat causes the mantle in that region to melt.
