In short, no. Most volcanoes are located in the ring of fire, which surrounds the Pacific Ocean. Most volcanoes are caused by subduction, which is when one plate is pulled under another. This is usually ocean crust under a continent which then melts and comes back to the surface as magma. Other volcanoes are hot spots caused by weak spots in the Earth's crust, such as the hot spot that created Hawaii.

What are examples of the theory of plate tectonics?
Sea floor spreading
What contribution did hess make to science?
He propounded the Sea-floor Spreading Theory.
What was Robert Dietz contribution to the tectonic theory?
he as the one who crated the sea floor spreading
Describe how magnetism is used to support the theory of seafloor spreading?
New material is added to the sea floor when sea floor spreading occurs. When the iron cools it is magnetized by the magnetic field of the earth.
Is the analysis of seafoor sediments evidence of sea-floor spreading?
Yes, the analysis of sea-floor sediments can provide evidence of sea-floor spreading. By studying the age and composition of the sediments, scientists can track the movement of tectonic plates and the spreading of the sea floor over time. Additionally, magnetic anomalies recorded in these sediments can further support the theory of sea-floor spreading.
Who had the sea floor spreading theory?
Harry Hess came up with the theory of seafloor spreading . Alfred Wegener came up with the idea of continental drift NOT sea-floor spreading.

What are examples of the theory of plate tectonics?
Sea floor spreading
What is one piece of evidence that supports sea floor spreading?
Mapping of magnetic anomalies on the ocean floor shows alternating bands of normal and reversed polarity, indicating that new oceanic crust is continuously forming at mid-ocean ridges and spreading away in opposite directions.
How many is the Earth's crust divided into?
Sea floor spreading theory
What magnetic reversals help support?
the theory of sea-floor spreading
What theory combined sea floor spreading and continental drift?
Plate Tectonics
What provides the most evidence for the theory of plates tectonic?
The spreading of the sea floor.
The earth's crust is divided into how many plates?
Sea floor spreading theory
What contribution did hess make to science?
He propounded the Sea-floor Spreading Theory.
What three pieces of evidence for Wegener's theory came from the sea floor?
seafloor spreading, age of the sea floor and ocean trenches.
What are the similarities of the continental drift theory sea floor spreading and the plate tectonics theory?
the similarities of this 3 theory is,,,, they are all theory....
