What is typically occurring when magmatism occurs far away from plate boundaries?
A) new oceanic crust is created at mid-ocean ridges
B) large volcanoes are built above subduction zones
C) some type of thermal disturbance is occurring in the mantle
D) all of these
Magmatism
The geological process involving the generation, movement, and solidification of magma or molten rock beneath the Earth's surface.
Plate Boundaries
Regions where two tectonic plates meet, which can result in geological activity such as earthquakes and volcanic eruptions.
Thermal Disturbance
Localized or widespread change in temperature that affects an area's thermal equilibrium, often caused by geological events.
- Interpret the role of hot spots, mantle plumes, and the different types of magmatism they produce.

Final Answer :
C
Explanation :
Magmatism far from plate boundaries is usually associated with thermal disturbances in the mantle, such as mantle plumes or hotspots, rather than the processes at mid-ocean ridges or subduction zones.
