What role does asthenosphere play in generating magma at a convergent boundary?

∙ 14y ago
At an oceanic subduction zone, the athenosphere is subducted under continental lithosphere, or under other oceanic lithosphere. Friction between these plates causes heat that creates magmas. At a divergent boundary upwelling mantle (athenosphere) decompresses due to reduced pressures, allowing magma to form. This magma is extruded onto the seafloor as pillow basalts, and beneath the seafloors as massive gabbros and sheeted (gabbro) dikes.

∙ 10y agoThe Asthenosphere which is also called the Weak Zone, is a layer of Earths internal structure found in the Mantle which is in semi-solid (molten) form. The Asthenosphere helps in the process of Plate tectonics, it serves as a medium for flow and movement of the lithosphere.

∙ 9y agoMagma is generated along convergent plate boundaries through partial melting of the subducting slabs. The fluids that are released from the slab aid in the melting of hot peridotite in the lithosphere.

∙ 14y agoThe entry of cold, wet oceanic crust into the asthenosphere at subducting convergent plate boundaries, causes the melting of the crust above it, creating magma.

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.
How are volcano island formed?
It is formed by a convergent boundary of an oceanic plate and continental plate when they hit each other and goes down into the asthenosphere thus making the magma to rise above the earth's surface making a volcano.Then it solidifies and therefore it makes a volcano island.
How is magma formed at the convergent boundary?
Water in the subducted rock is released into the asthenosphere. The water lowers the melting temperatures of materials in the asthenosphere, leading to the formation of magma. i dot think this is right so who ever did this take it back
Is The asthenosphere is a region in the earth where magma chambers form?
Yes. That is what the asthenosphere is.
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.
