At convergent plate boundaries, magma forms primarily due to the subduction of one tectonic plate beneath another. As the descending plate sinks into the mantle, it encounters increased pressure and temperature, causing the release of water and other volatiles from the subducting sediments and rocks. This process lowers the melting point of the overlying mantle material, leading to the formation of magma, which can then rise to create volcanic activity.

What type of plate boundary triggers the formation of active volcanoes as magma rises beneath the surface?
Oceanic-to-Oceanic plate boundary triggers the formation of active volcanoes as magma rises beneath the surface.Transform plate boundaries trigger the formation of active volcanoes as magma rises beneath the surface.
What type of plate boundary is the southeast Indian ridge?
The southeast Indian Ridge is a divergent plate boundary, where two tectonic plates are moving away from each other. This movement causes magma to rise from the mantle, creating new crust as the plates separate.
What causes magma to form at a divergant plate?
At a divergent plate boundary the crust is thin. This reduces pressure on the upper mantle, lowering the melting point and allowing some rock to melt.
How does a volcano erupt at a convergent boundary?
As an oceanic plate sinks into the mantle at a convergent boundary it causes rocks to melt. Some of the newly formed magma will migrate upward to volcanoes, that have formed along the convergent boundaries, and erupt.
Is Mt Etna on a convergent divergent or transform plate boundary?
Mount Etna Was Formed By Destructive Plate Boundaries. This Is When One Crust Is Forced Under Another Crust. It Stands At The Convergent Boundary Where The African Crust Is Being Sub Ducted Beneath The Eurasian Crust. This Causes The Latter To Deform And Forces the Magma Up Into Weak Spots In The Earths Crust (mount Etna) When There Has Become To Much Of A Magma Build Up In The Mantle.

What kind of plate boundary causes mountains to form?
The plate boundary that causes mountains to form is called a convergent boundary.
What plate boundary causes seismic waves?
Destructive plate boundary.
What type of plate boundary is the southeast Indian ridge?
The southeast Indian Ridge is a divergent plate boundary, where two tectonic plates are moving away from each other. This movement causes magma to rise from the mantle, creating new crust as the plates separate.
What causes magma to form at a divergant plate?
At a divergent plate boundary the crust is thin. This reduces pressure on the upper mantle, lowering the melting point and allowing some rock to melt.
What causes volcano to form at a diverging plate boundary?
When a huge piece of crust diverges (pulls apart), the crust becomes fractured and magma spills out on the surface.
