Volcano's are caused by the dense oceanic plate being sub ducted under the lighter continental plate, this causes immense pressure as the oceanic crust enters the mantle it melts, this magma is forced to create a chamber creating rock as it cools, this results in a volcano being formed, volcano's have to erupt occasionally to disperse the pressure that is built up by the oceanic plate going under and melting under the continental plate.

Volcanoes occur along constructive plate boundaries due to the upwelling of magma from the mantle as tectonic plates move apart. At destructive plate boundaries, volcanoes form because one tectonic plate is forced beneath another in a process called subduction, leading to the melting of crustal rocks and the formation of magma.

An earthquake is most likely to occur at the edge of a continental plate because it is caused by the collision of two plates. A volcano occurs because the flow of magma is less restricted around the continental plates' outer shelves.

They occur along constructive plate boundaries because the heat of the mantle is greatest there and magma is upwelling.

They occur along destructive boundaries because while the the rocks are cold and wet, as they sink they are warmed by the mantle heat and partial melt magmas are famed which rise to the surface.

The important point to note is because of this difference, the type of magma (and volcano) found at a constructive plate boundary is different from the magma and volcano type at found at a destructive plate boundary.

When the plates push against each other, the pressure is translated into upward motion- mountains are formed.

How volcanes distributed?

Volcanoes are typically distributed along plate boundaries, known as the Ring of Fire, or can occur in hot spots like Hawaii. They can also be found along mid-ocean ridges where tectonic plates are spreading apart. Some volcanoes form within the interior of plates due to hotspots, like the Yellowstone supervolcano.


Are volcanoes more common along a convergent or divergent boundary?

Volcanoes are more common along convergent boundaries where two tectonic plates collide, causing subduction and the melting of rock. Divergent boundaries also have volcanoes, but they are typically less explosive and occur as a result of magma rising to fill the gap created by the moving plates.
