How does subduction st converging plate boundaries lead to the formation of volcanoes?

The older denser plate sinks under a deep ocean trench into the mantle. Some rock above the subducting plate melts and forms magma. Since the magma is less dense than the surrounding rock, it rises toward the surface. Eventually, the magma breaks through the ocean floor, making a volcanoe.

∙ 13y 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.

∙ 13y agoAs one of the plates is being subducted into the mantle, the plate melts and creates extra magma in the mantle. Because of this there is a higher pressure in the mantle and the extra magma that was melted from the plate forces it's way up to the surface. After several eruptions, volcanoes are made.

∙ 11y agoAt a convergent boundry crustal plates meet, and typically one is forced under the other in a process of subduction. Crustal rock tends to melt more easily than mantle rock, it carries water and other volatiles and the friction and compression between the plates causes heating. These combine to cause the subducted plate to partially melt as it is subducted.
The melted rock is magma, which makes its way to the surface via cracks and can form explosive volcanic eruptions, as it is often viscous and has lots of volatiles.

What can result from the action of plates at a converging boundary?
moderate earthquakes, volcanoes, formation of mountains and subduction zones
What two boundaries exist that cause the volcanoes to exist along the Cascade Range in the Pacific Northwest?
The Juan de Fuca plate is converging (convergent/destructive plate boundary) with the North American plate creating the Cascadia subduction zone.
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 plate boundary is a composite volcano on?
Composite volcanoes most often are found near subduction zones. They can be found at either oceanic-oceanic convergent plate boundaries, oceanic-continental plate boundaries, or continental-continental plate boundaries. They are especially prevalent in the Pacific Ring of Fire. A few composite volcanoes, however, have been found at divergent boundaries and away from plate boundaries at hot spots.
Which type of plate boundaries produce volcanoes?
Continental and Oceanic plates.
What can result from the action of plates at a converging boundary?
moderate earthquakes, volcanoes, formation of mountains and subduction zones
Do volcanoes form on diverging or converging plate boundaries more?
Most are found on converging
Where volcanoes occur?
volcano occur in hot spot and diverging boundaries and converging boundaries.
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 causes volcanoes to form at spreading boundaries?
Please make the question clearer. There are converging and diverging boundaries but not spreading boundaries. Plates move but don't spread. Please make the question clearer
What are two ways volcanoes can forms near converging plate boundaries?
Volcanoes may form where two oceanic plates collide or where an oceanic plate collides with a continental plate.
What are two Ways volcanoes Form near converging plate boundaries?
Volcanoes may form where two oceanic plates collide or where an oceanic plate collides with a continental plate.
What happens along a plate boundary that leads to high occurrences of volcanoes?
Subduction happens along plate boundaries which pushes up magma which then creates volcanoes.
