Detailed explanation-1: -When oceanic crust collides with a continent, an oceanic-continental convergent boundary forms. The oceanic plate is denser, so it undergoes subduction . This means that the oceanic plate sinks beneath the continent, forming a deep ocean trench.
Detailed explanation-2: -When continental and oceanic plates collide, the thinner and more dense oceanic plate is overridden by the thicker and less dense continental plate. The oceanic plate is forced down into the mantle in a process known as “subduction.” As the oceanic plate descends, it is forced into higher temperature environments.
Detailed explanation-3: -As the plates collide, the denser plate will sink beneath the other plate, producing a subduction zone. This process is known as subduction. As the oceanic plate is pushed deeper into the mantle, volcanoes and mountain ranges may form.
Detailed explanation-4: -Subduction is a geological process in which the oceanic lithosphere and some continental lithosphere is recycled into the Earth’s mantle at convergent boundaries.
