subduction, which is when one tectonic plate is pushed down beneath another tectonic plate.
Oceanic crust sinks beneath trenches through a process known as subduction. As oceanic plates collide with continental plates, the denser oceanic plate is forced downward into the mantle due to gravitational pull. This creates a subduction zone where the oceanic crust eventually melts and is recycled back into the mantle.
plate tectonics
Deep-oceanic trenches are most abundant around the rim of the Pacific. Deep ocean trenches are surficial evidence for sinking of oceanic lithosphere into the mantle at a subduction zone.
They are called trenches.
Continental crust cannot form as a result of oceanic-oceanic convergence. This process typically results in the formation of volcanic island arcs or deep-sea trenches. Continental crust is formed through processes like continental collision and accretion of terranes.

This creates a subduction zone where the oceanic crust eventually melts and is recycled back into the mantle.
They form when the oceanic crust goes under the Continental crust. The oceanic crust then forms the trenches through a process called subduction.

Deep-oceanic trenches are most abundant around the rim of the Pacific. Deep ocean trenches are surficial evidence for sinking of oceanic lithosphere into the mantle at a subduction zone.
Convergence can occur between oceanic-oceanic, oceanic-continental, and continental-continental plates. This process typically leads to the formation of mountain ranges, deep ocean trenches, and volcanic arcs.
Convergent trenches are deep oceanic features where two tectonic plates collide and one is forced beneath the other in a process called subduction. This movement can lead to the formation of volcanic arcs, earthquakes, and the recycling of oceanic crust back into the mantle. Many of the Earth's largest and deepest earthquakes occur along convergent trenches.
Convergent oceanic-oceanic boundaries occur when two oceanic plates collide. One plate is usually subducted beneath the other, leading to the formation of deep ocean trenches and volcanic island arcs. This process can result in intense geologic activity, such as earthquakes and volcanic eruptions.
