Which of the following geologic regions produces the greatest volume of magma?
Subduction zones produce the greatest volume of magma due to the subduction of one tectonic plate beneath another, allowing for the melting of rock and the formation of magma. This process is associated with volcanic arcs and chains of stratovolcanoes, contributing to significant magma production.
What geologic regions produces the greatest volume of magma?
Subduction zones, where one tectonic plate slides beneath another, tend to produce the greatest volume of magma. The intense heat and pressure created during this process can cause melting of the subducted plate, leading to significant magma production. This magma can rise to the surface and result in volcanic activity.
What type of magma produces pahoehoe?
Pahoehoe is typically formed from low-viscosity basaltic magma that is rich in iron and magnesium. This type of magma allows for the smooth, rope-like texture characteristic of pahoehoe lava flows.
What process is evident at oceanic trenches?
subduction, which is when one tectonic plate is pushed down beneath another tectonic plate.
What type of plate bondary makes up Mount Mazama?
Mount Mazama was formed by the collision of two tectonic plates along a convergent boundary. Specifically, it was caused by the subduction of the Juan de Fuca Plate beneath the North American Plate in the Cascadia Subduction Zone.

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 produces pahoehoe?
Pahoehoe is typically formed from low-viscosity basaltic magma that is rich in iron and magnesium. This type of magma allows for the smooth, rope-like texture characteristic of pahoehoe lava flows.
Magma that is low in silica and produces nonexplosive eruptions?
Low viscosity mafic magma.
What process is evident at oceanic trenches?
subduction, which is when one tectonic plate is pushed down beneath another tectonic plate.
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.
What type of plate bondary makes up Mount Mazama?
Mount Mazama was formed by the collision of two tectonic plates along a convergent boundary. Specifically, it was caused by the subduction of the Juan de Fuca Plate beneath the North American Plate in the Cascadia Subduction Zone.
What happens to magma when it produces igneous rocks?
The transition form magma to rock is a process of cooling.
How does magma become a igneous rock?
Igneous rock, if heated sufficiently by subduction processes will melt to form magma.
What rock would probably form if magma that was feeding volcanoes above subduction zones solidified at consideration depth?
A type of rock that would likely form from magma solidifying at considerable depth beneath subduction zones is basalt. Basalt is a common igneous rock formed from the solidification of mafic magma, which is typical of volcanic activity at subduction zones. It is fine-grained and commonly found in the oceanic crust formed at these zones.
How does subduction effect Volcanoes?
Subduction zones are locations where two tectonic plates collide, with one plate sliding beneath the other. This process can lead to the melting of the subducted plate, producing magma that rises to the surface and results in volcanic activity. Volcanoes located along subduction zones tend to be more explosive due to the higher water content in the subducted plate, which can lead to the formation of andesitic magma.
