What process causes volcanoes to form near converging plate boundaries?

At convergent boundaries involving an oceanic plate, or between oceanic plates, the heavier (more dense) oceanic plate subducts, or moves downward, underneath the less dense plate toward the mantle. As temperature increases with depth, and with the introduction of water contained within the subducting crust, partial melting occurs. The melted rock, or magma, is more buoyant than the surrounding rock, and will seek to rise toward the surface through cracks and fissures as well as by the assimilation of the surrounding rock. If it reaches the surface before solidifying, it will erupt, forming a volcano.

What type of plate boundary causes volcanic eruptions?
There are two plate boundaries that cause volcanoes. They are the divergent and convergent plate boundaries.
What happens at colliding boundaries?
these boundaries are formed when two plates collide. When the two plate bump one plate is absorbed in the mantle of the other. Heat and pressure when these plates collide causes volcanoes and earthquakes.
What boudaries produces volcanoes?
Convergent boundaries produce volcanoes. Volcanoes form when an oceanic plate and a continental plate converge, causing the oceanic plate to subduct. The subduction causes a magma chamber to form which feeds the volcano when it erupts.
Why are most volcanoes located near a fault?
Most volcanoes form at either convergent or divergent plate boundaries. Volcanoes at convergent plate boundaries form when one plate slides under another, taking seawater with it. This causes the rock in the mantle to melt as the melting point drops. This new magma can rise to form volcanoes.At divergent plate boundaries the crust is thing, which lowers pressure on the mantle, causing some material to melt.
What causes volcanoes to form at spreading plate boundaries?
As two plates spread apart from each other at the boundary, magma that was trapped below wells up between them. This magma can be released in the form of volcanoes or ooze out from rift valleys.
What process causes mountains to be built?
converging plate boundaries
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 plate process causes volcanoes to form at their boundaries?
the plate of your mom

There are two plate boundaries that cause volcanoes. They are the divergent and convergent plate boundaries.
What is the process that causes and earthquake?
Earthquakes are caused by transform faults and when stress overcomes friction. volcanoes are caused by convergent boundaries, the process of convergent boundaries is when two plates come in contact with each other. ex. for volcano is a oceanic plate sub ducts under a continental plate.

What happens at the boundaries of tectonic plates?
if it's a convergent (--> <--) boundary, one plate slides under another and usually forms volcanoes or trenches divergent (<-- -->) forms a ridge where new crust forms transform is when two plates slide past each other, and it causes earthquakes
What causes volcanoes to form at spreading plate boundaries?
As two plates spread apart from each other at the boundary, magma that was trapped below wells up between them. This magma can be released in the form of volcanoes or ooze out from rift valleys.
What causes volcano's to form?
Volcanoes can be caused by mantle plumes. These so-called hotspots can occur far from plate boundaries. Hotspot volcanoes are also found elsewhere in the solar system, especially on rocky planets and moons. Volcanoes can also form where there is stretching and thinning of the Earth's crust.
At which plate boundaries do most volcanoes form?
Most volcanoes form at a convergent plate boundary. Simply put when a oceanic plate and a continental plate hit each other face on the subduction of the oceanic plate causes the magma to rise and the converging of the plates makes a mountain and the magma rises through the top creating a volcano.
