The deepest portions of the subducting plate get pulled under by the subducted plate. This is how the trench is formed. this process is at work when any subduction occurs.
An oceanic-continental subduction occurs when ocean crust sinks under continental crust. The oceanic crust sinks because it is colder and denser than the continental crust. At these sites, deep-ocean trenches form, along with coastal mountains.
What else can I help you with?
Do convergent boundaries have trenches?
Yes, convergent boundaries can have trenches. Trenches are often found at subduction zones where one tectonic plate is being forced beneath another plate. The descending plate forms a trench as it sinks into the mantle.
Explain the relationship between trenches and seafloor spreading?
1. New sea-floor is created by the upwelling of magma at mid-ocean spreading centers; old ocean floor is destroyed by subduction at deep sea trenches. 2. The area is a subduction zone. Magma from underground comes up and destroys that crust. That crust is then recycled and the magma cools and hardens. That creates new land, that creates the trenches. Seafloor spreading is in the ocean and happens with convection currents. That is the relationship between. 3. As new seafloor is formed at mid-ocean ridges, the old seafloor is pushed down into trenches at subduction zones.
What do volcanic belts form along on?
Both subduction zones and spreading centers.
What is similar between ocean trench and mid-ocean ridge?
Both the ocean trench and mid-ocean ridge are features found on the ocean floor as part of the oceanic crust. They are formed by tectonic processes, with ocean trenches created by the subduction of one tectonic plate beneath another, while mid-ocean ridges are formed by the divergence of tectonic plates, leading to the upwelling of magma and the creation of new oceanic crust.
Where are volcanoes that erupt in both ways?
The volcanoes that erupt both ways are located on or near boundaries between oceanic and continental crust over subduction zones.
What are two kinds of crust involved in a subduction zone?
Both continental and oceanic crusts are used in the process of subduction, unless you are talking about see floor spreading, then only oceanic crust is used
Do convergent boundaries have trenches?
Yes, convergent boundaries can have trenches. Trenches are often found at subduction zones where one tectonic plate is being forced beneath another plate. The descending plate forms a trench as it sinks into the mantle.
Explain what plate tectonics and ocean trenches have in common?
Ocean trenches and volcanoes both occur where continental plates collide, or meet. An Ocean trench is also noted for the presence of a volcanic arc. This is right no joke:)

What was the series of trenches dug by both sides in northern France?
They were the western front. But the different trenches were front line trenches, communication trenches.
Do convergent plate boundaries form mountain ranges or subduction zones?
Convergent plate boundaries can form both mountain ranges and subduction zones. Mountain ranges are typically formed when two continental plates collide, leading to compression and uplift of the crust. Subduction zones are formed when an oceanic plate is forced beneath another plate, usually resulting in the formation of deep ocean trenches and volcanic activity.
Why wern't trenches used in World War 2?
Trenches were used in both WWI and WWII.
Where did England fought in trenches or sea?
Both
How do valleys and trenches differ?
They are both giant holes in the ground. Trenches are found underwater and valleys are found on land.
What in earths interior causes subduction and sea floor spreading?
Subduction and sea floor spreading are both a result of the movement of the tectonic plates.Plate Tectonics
Describe the three types of plate collisions that occur along convergent boundaries?
There are three types of plate collisions. They are classified by the type of crust involved in the collision. Plate collisions fall into these three types: 1. Both plates have an oceanic leading edge, 2. One plate has a continental leading edge and the other has an oceanic leading edge, and 3. both plates have a continental leading edge
What do volcanic belts form along on?
Both subduction zones and spreading centers.
