Detailed explanation-1: -When an oceanic plate converges with a continental plate, the oceanic crust will always subduct under the continental crust; this is because oceanic crust is naturally denser.
Detailed explanation-2: -If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. Deep trenches are features often formed where tectonic plates are being subducted and earthquakes are common at subduction zones as well.
Detailed explanation-3: -Subduction of an oceanic plate beneath a continental plate causes earthquakes and forms a line of volcanoes known as a continental arc. The movement of crust and magma causes earthquakes. Remember that the mid-ocean ridge is where hot mantle material upwells in a convection cell.
