When an oceanic plate subducts into the Earth's hot interior, it sinks beneath a continental or another oceanic plate, leading to the formation of a trench. As the plate descends, it heats up and releases water and other volatiles, which can trigger melting in the overlying mantle. This process often results in volcanic activity and the creation of magma, contributing to the formation of volcanic arcs. Additionally, this subduction can lead to earthquakes due to the intense pressure and friction between the plates.
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.
This process is known as subduction and occurs at convergent plate boundaries because oceanic crust is denser than continental crust.
when oceanic crust and continental crust collide, the oceanic crust sinks down beneath the continental crust. this is called subduction.
oceanic as it is colder; therefore denser
Subduction of oceanic plates under continental plates occurs at convergent plate boundaries, where the plates are moving toward each other. When an oceanic plate meets a continental plate, it is usually the one subducted, due to its greater density. The Pacific "Ring of Fire", particularly east to south east Asia and the west coast of South America, is the result of oceanic plate subduction, and hence there is a high number of earthquakes and volcanism in the area.

the oceanic plate
Yes. Such areas are called subduction zones. They develop where two tectonic plates converge and at least one plate is made of oceanic crust. The denser oceanic plate sinks into the mantle.
It is called subduction and only occurs in oceanic to oceanic or oceanic to continental plate collisions.

At an oceanic continental plate boundary, a process called subduction occurs, where the denser oceanic plate is forced beneath the less dense continental plate due to the difference in their densities. This leads to the formation of deep oceanic trenches and volcanic arcs on the overriding continental plate.
Subduction occurs when one tectonic plate moves underneath another plate at a convergent boundary. This typically happens at deep ocean trenches where the denser oceanic plate is forced beneath the less dense continental plate. Subduction is a key process in the cycle of plate tectonics, leading to the formation of volcanic arcs and earthquakes.

Oceanic plate diverge
This usually is where and how mountains ranges are formed. Volcanism can also result from the subduction melting of the oceanic crust.
When an oceanic plate moves under a continental plate, a subduction zone is formed. The oceanic plate is forced down into the mantle, where it melts and creates magma. This magma can then rise to the surface, causing volcanic activity on the continental plate.
