Which feature can be produced at an ocean-continental convergence?

During an ocean-continental convergence, features like ocean trench, volcanoea and can be produced.

Ocean-continental convergence occurs at destructive/convergent plate boundary, where the denser oceanic plate subducts under the less dense continential plate under the sinking convection current of magma.

Ocean trench is produced as the oceanic plate is pushed under the continential plate, and the lithosphere/sea floor is bended to form a depression.

Volcanoes on the other hand,is formed as the continential crust bend under the pressure to form cracks, which allows magma to rise and cause fissure eruption. After repeated fissure eruption,the cooled down material will form a cone-shaped volcano with a vent that allowa magma to went through.

Hope it helps!
