GEOLOGY

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: -Plates Subduct When an ocean plate collides with another ocean plate or with a plate carrying continents, one plate will bend and slide under the other. This process is called subduction.

Detailed explanation-3: -Ocean-Continent Convergence-Continental lithosphere is less dense than oceanic lithosphere so the latter always subducts beneath the former. Andesitic magma rises from the subduction zone to form a magmatic arc on the continental crust.

Detailed explanation-4: -When two oceanic plates collide, the denser plate is subducted and some material rises upward and forms an ISLAND.
