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.
What else can I help you with?
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 the boundary of the devils tower convergent?
The boundary of Devil's Tower is not a convergent boundary. It formed through volcanic activity, where magma solidified underground and was then exposed through erosion. This process created the distinct shape of Devil's Tower.
Is Krakatoa a divergent convergent or transform boundary?
Krakatoa is located at a convergent boundary, where the Indo-Australian Plate is being subducted beneath the Eurasian Plate. This subduction zone can lead to intense volcanic activity due to the melting and rising of magma from the subducted plate.
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
What causes magma to form at a convergent boundary?
the mid ocean ridges cause the magma to form at a convergent plate boundary.
What causes Magma to form a convergent plate boundary?

How do the plates and mantle interact at a convergent plate boundary?
At a convergent plate boundary, where two tectonic plates collide, one plate is forced beneath the other in a process called subduction. The descending plate sinks into the mantle, causing it to melt and create magma. This magma can then rise to the surface, leading to volcanic activity. The interaction between the plates and the mantle at a convergent boundary is dynamic and can result in the formation of mountain ranges, earthquakes, and volcanic arcs.
What is the initial cause of magma formation in the asthenosphere beneath Yellowstone?
