oceanic trenches occur where tectonic plates collide and one is pushed underneath the other.
Trenches are most likely to occur at convergent plate boundaries, where tectonic plates collide and one is forced beneath the other in a process called subduction. This creates deep oceanic trenches, such as the Mariana Trench in the western Pacific Ocean, which is the deepest known trench on Earth.
i do not no sorry

Java Trench
The ocean trench is almost 7 miles deep.
It is the deepest trench in the whole ocean.
