How does subduction at converging plate boundary's lead to the formation of volcanoes?

∙ 7y ago
When the denser plate subducts (usually the oceanic crust) it gets pushed down into the hot asthenosphere and melts a little. this causes the magma created from the melting to rise up and shoot out of the earth's crust, forming a volcano.

∙ 14y agoThe water and sediments on the oceanic plate (the one being subducted) are subjected to high temperatures and pressures when they reach a certain depth. The water, combined with magma (melted sediments from both plates), works its way up through the continental plate, and volcanoes are formed where the magma breaches the surface.

What can result from the action of plates at a converging boundary?
moderate earthquakes, volcanoes, formation of mountains and subduction zones
What geological feature does subduction zones cause?
Subductions zones result in the formation of a trench and also volcanoes on the overriding plate
Where are the most explosive volcanoes subduction zones or rift zones?
Explosive volcanoes are most common at subduction zones.
How are subduction and volcanoes related?

Is Shield volcanoes found along subduction zones?
Cone volcanoes which are likely to erupt explosively are found at subduction zones. Spreading zones (constructive plate boundaries) and hot spots produce quieter volcanoes because their lava is thinner. The ones at hot spots are shield volcanoes.
What can result from the action of plates at a converging boundary?
moderate earthquakes, volcanoes, formation of mountains and subduction zones
Which of the boundarys can produce volcanoes?
convergent
Movement of lithospheric plates allows for the formation of volcanoes?
Movement of lithospheric plates at convergent boundaries can result in the subduction of one plate beneath another. This subduction creates conditions for magma to form as the subducting plate melts. The rising magma then reaches the surface, leading to the formation of volcanoes.
What geological feature does subduction zones cause?
Subductions zones result in the formation of a trench and also volcanoes on the overriding plate
How are the mountains that are formed by subduction diffrent from mountains formed by continental crusts converging?
Subducting crust produces volcanoes and a narrow range of mountains (like the Andes). Continental convergence does not produce volcanoes and produces a wider range of mountains (Rockies or Himalayas).
Do volcanoes form on diverging or converging plate boundaries more?
Most are found on converging
Where are the most explosive volcanoes subduction zones or rift zones?
Explosive volcanoes are most common at subduction zones.
What are the steps in continent mountain formation?
Continents and mountains are sometimes formed by volcanoes that occur on an arc near a subduction zone. The activity of the volcanoes can cause shifts in the plates that form mountains and lift continents.
Do Hotspot volcanoes occur along subduction zones.?
No, hotspot volcanoes do not occur along subduction zones. They occur when plates pass over mantle hot spots.

What are the steps in arc continent mountain formation?
Continents and mountains are sometimes formed by volcanoes that occur on an arc near a subduction zone. The activity of the volcanoes can cause shifts in the plates that form mountains and lift continents.
What are the steps in arc-continent mountain formation?
Continents and mountains are sometimes formed by volcanoes that occur on an arc near a subduction zone. The activity of the volcanoes can cause shifts in the plates that form mountains and lift continents.
