Magma does not "leak" out in a subduction situation, it does rise after the melting of the subducted plate and eventually rupture the crust and possibly create a volcano. In the area of contact, where the two plates collide, no magma leaks. Consider that the crust is miles thick and IF any magma were to go through cracks in the crust where the collision occurs, it would move slowly (the fastest of moving crusts move mere inches a year) and before it reaches the surface to leak, it will harden and fill what was once a crack, with hardened rock. So no, magam will not "leak".

What happens during subduction important to rock cycle?
During subduction, one tectonic plate moves beneath another into the mantle. This process can cause melting of the descending plate, leading to the formation of magma. This magma can then rise to the surface through volcanic activity, contributing to the formation of new igneous rocks and completing the rock cycle.
How is magma created in a subduction zone?
Magma is created in a subduction zone when one tectonic plate is forced beneath another plate. The intense pressure and heat cause the subducted plate to melt, forming magma that rises to the surface and can lead to volcanic activity.
How is magma generated along subduction zones?
Magma is generated along subduction zones when oceanic plates are forced beneath continental plates. The intense heat and pressure cause the oceanic plate to melt, creating magma that rises to the surface and forms volcanoes.
Where is andesitic magma found?
Andesitic magma is commonly found in subduction zones where oceanic crust is being forced beneath continental crust. These environments are typically associated with volcanic arcs and stratovolcanoes. Examples of where andesitic magma is found include the Andes Mountains in South America and the Cascades in the western United States.
What type of magma does mount shasta have?
Mount Shasta typically has andesitic magma, which is a type of intermediate magma that is common in subduction zone environments. This type of magma is rich in silica and forms from the partial melting of both oceanic and continental crust.
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.
What happens to excess magma created in a subduction zone?
In a subduction zone, excess magma generated from the melting of the subducting plate and surrounding mantle material typically rises to form volcanic arcs. This magma can lead to the creation of volcanoes as it accumulates in magma chambers beneath the Earth's surface. Eventually, some of this magma erupts, contributing to volcanic activity, while the remainder may solidify underground, forming intrusive igneous rocks. Over time, continuous subduction can lead to the growth of mountain ranges and the formation of new landmasses.
What happens after magma erupts along mid ocean?
The magma spills over the ridge and pushes the old sea floor away toward a subduction zone where the old sea floor melts.
What happens during subduction important to rock cycle?
During subduction, one tectonic plate moves beneath another into the mantle. This process can cause melting of the descending plate, leading to the formation of magma. This magma can then rise to the surface through volcanic activity, contributing to the formation of new igneous rocks and completing the rock cycle.
What happens when an oceanic plate moves under a continental plate?
When an oceanic plate moves under a continental plate, a subduction zone is formed. The oceanic plate is forced down into the mantle, where it melts and creates magma. This magma can then rise to the surface, causing volcanic activity on the continental plate.
How is magma created in a subduction zone?
Magma is created in a subduction zone when one tectonic plate is forced beneath another plate. The intense pressure and heat cause the subducted plate to melt, forming magma that rises to the surface and can lead to volcanic activity.

What happens to magma after it erupts onto the ocean floor?
The magma spills over the ridge and pushes the old sea floor away toward a subduction zone where the old sea floor melts.

Andesitic magma is commonly found in subduction zones where oceanic crust is being forced beneath continental crust. These environments are typically associated with volcanic arcs and stratovolcanoes.

What happens in an ocean trench?
Subduction
What happens at colliding boundries?
subduction happens and mountains and volcanoes form
What was obsidian before it was obsidian?
It was liquid rock (magma) which solidified after an extrusion or eruption. Crustal rocks can re-dissolve into magma during subduction of oceanic crust.
