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?
Magma that is low in silica flows readily and produces dark-colored lava. Therefore magma that is low in silica produces Pahoehoe lava. This is called mafic or basaltic magma.
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.

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.

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.
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.
Magma that is low in silica and produces nonexplosive eruptions?
Low viscosity mafic magma.
What type of magma produces pahoehoe?
Magma that is low in silica flows readily and produces dark-colored lava. Therefore magma that is low in silica produces Pahoehoe lava. This is called mafic or basaltic 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 happens to magma when it produces igneous rocks?
The transition form magma to rock is a process of cooling.
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.
How does magma become a igneous rock?
Igneous rock, if heated sufficiently by subduction processes will melt to form magma.
