When the two plates collide, the oceanic plate is pulled under the continental plate. As the plate is pushed further down, heat and pressure increase, which causes the crust to melt and form magma, Volcanoes are created along the plate collision to release the pressurized magma.
Rift volcanoes form at divergent plate boundaries where tectonic plates are moving away from each other. As the plates separate, magma rises up to fill the gap, leading to volcanic activity. This results in the formation of long chains of volcanoes along the rift zone.
As the crust spreads at a rift, it thins, and faulting occurs, as the rock between the faults moves wider apart, magma from the earth's interior rises to fill that space. Eventually the magma rises to the surface and forms a volcano
Volcanoes cannot be formed at a continental rift, due to the fact that a volcano cannot form between two continental plates: it normally forms when one continental plate and an oceanic plate collide.
Normally, a volcano forms when one continental and one oceanic plate collides. The denser oceanic plate
Rift volcanoes form when magma rises into the gap between diverging plates. They
thus occur at or near actual plate boundaries.

Explain how volcanoes form in the central rift valley of a divergent boundary?
Earthquakes occur along the faults, and volcanoes form when magma reaches the surface, and then the valleys form from erosion.
Do composite volcanoes form at subduction?
Usually, yes. Occasionally, though they can form in rift zones or at continental hotspots.
What can form above subduction zones?
I think it would be shield volcanoes because it was it!
Why are rift zones a common spot for igneous rock to form?
The thinned crust in rift zones results in the formation of magma (molten rock) in the upper mantle, which then rises through the crust. As a result, rift zones often have active volcanoes, which form new igneous rocks.
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 types of volcanoes form at mid-ocean ridges?
Rift volcanoes.
Are shield volcanoes hot spots?
Shield volcanoes are not hot spots but they are associated with them. However, such volcanoes can also form at rift zones.

mountains, volcanoes, rift valleys, fault lines,

What are the characteristics of a rift valley?
Igneous. Crustal material is added in rift valleys by the addition of magma.
Do most volcanoes form near colliding plate boundaries?
Most volcanoes do form near colliding plate boundaries where subduction occurs, such as the Ring of Fire in the Pacific Ocean. However, volcanoes can also form in other geologic settings, such as hotspots and rift zones.
Where do large number of volcanoes form?
A large number of volcanoes form along the boundaries of tectonic plates, where the earth's crust is weak and molten rock (magma) can rise to the surface. These boundary regions include areas such as the Ring of Fire in the Pacific Ocean and the East African Rift.
Where are the most explosive volcanoes subduction zones or rift zones?
Explosive volcanoes are most common at subduction zones.
