What is the difference between the volcanic activity that occurs at a hot spot and the volcanic activity at a subduction boundary between an oceanic plate and a continental plate?

The hot spot volcanic activity is not dependent on the subduction and melting of oceanic crust. The hot spot simply appears to be a non-moving place in the Earth's mantle where heat rises from the interior.

Does most volcanic activity take place in continental interiors or along plate boundaries?
It could be both. There are massive rising plumes (columns) of magma that are scattered all around the Earth. It doesn't make a difference wether it's on a boundary or not.
Why do many earthquakes but few volcanic eruptions occur in the himalaya?
because it is at a converging boundary which means that the plates are coming together which causes earthquakes.This is because the Himalaya Mountains are a result of continent-continent collision and vulcanism in destructive boundaries results from subduction of oceanic plates. As the Indo-australian plate continues to collide with the Eurasian plate, subduction is no longer possible. The resulting stresses are relieved mostly from very large strike-slip faults. This results in much seismic activity, or earthquakes.-JenniPennehMore earthquakes and few volcanic eruptions occur in the Himalayas because volcanoes mostly occur when there is a transform boundary and subduction takes place between an oceanic plate and a continental plate. When the oceanic plate goes under the continental plate, subduction, the cool water from the ocean lowers the melting point of the rock it is under and allows magma to form easily. Then the magma rises upward(when magma is less dense than the rock surrounding it, it rises) and eventually goes through the surface creating a volcanic eruption.
What can be produced at an ocean-continental convergent boundary?
Ocean-continental convergent boundaries can produce earthquakes and volcanic activity. As the ocean plates shift under each other they near their melting temperature and can form magma and solidify to form underwater mountain ranges.
Which type of boundary do most earthquakes occur why?
Plate boundaries around Japan are convergent boundaries ie two plates are sliding towards each other. Japan has been formed as a result of the subduction of the Philippine Sea Plate beneath the continental Amurian Plate and Okinawa Plate to the south, and subduction of the Pacific Plate under the Okhotsk Plate to the north.
What type of plate margin was the Japanese earthquake?
it is on a convergent plate boundary also known as a subduction zone
When an oceanic plate is pushed under a continental plate resulting in volcanic activity what type of boundary is formed?
Convergent Boundary (Subduction Zone)
When an oceanic plate is pushed under a continental plate resulting in volcanic activity this type of boundary forms what?
it causes subduction <-- wrong convergent <-- right
What type of boundary does subduction occur at?
It accurs with oceanic and continental boundaries
What type of boundary forms when an oceanic plate is pushed under a continental plate?
a convergent boundary. The oceanic plate is then subducted under the continental plate because it is denser. This subduction creates earthquakes and volcanoes
What is it called when one plate is pushed under another plate as the collide?
subduction boundary!!!
What is the type of plate boundary where two plates move together causig one of the slabs of lithosphere to descend into the mantle beneath an overriding plate?
Convergent BoundaryA destructive plate boundary with a subduction zone.
What boundary is it called when an oceanic plate descends beneath a continental plate?
It's called destructive plate margin/boundary, or convergent plate margin though this term applies to all plate margins where two plates are moving towards each other (such as continental + continental or oceanic + oceanic).
Convergent boundary with no subduction?
A convergent boundary with no subduction is a continental-continental boundary. Because oceanic crust is denser than continental crust, it is always the subducting plate in a oceanic-continental boundary. In an oceanic-oceanic boundary, one of the plates will subduct, depending on several factors. Continental plates are thicker and less dense than oceanic plates, and when they converge, they push up the area where the plates meet, forming mountain ranges (note that this is not the only, or even the predominant, method of mountain formation). The Himalayas are being formed as a result of a continental-continental boundary.
At what type of boundary did the 1960 Chilean earthquake occur?
At a convergent boundary between oceanic and continental crust where subduction is occurring.
What geologic features are associated with each type of convergent boundary?
Subduction zones, trenches and volcanic islands: the boundary that is oceanic. Trenches and volcanic islands: an oceanic-continental boundary. Folded mountain ranges: a continental and continental collision.
Why does ocenaic crust sink beneath the continental crust at a subduction boundary?
The oceanic crust is denser than the continental crust.
What are types of convergents boundaries?
Converging (destructive) plate boundary: where two plates collide. Diverging (constructive) plate boundary: where two plates move away from each other. Transform plate boundary: where two plates move, or grind, past each other. Like the boundary in California.
