The tectonic plates, oceanic-to-oceanic convergent boundaries or oceanic-continental convergent boundaries create the ocean trenches. One of the plates that is denser than the other is pushed downwards into the mantle of the Earth by the lighter, and less dense plate. This creates the trench due to the downward motion of the plate. The denser plate's gravity will pull the rest of the plate down with it with time.
Divergent Boundaries underwater is only present at oceanic ridges. This creates the seafloor spreading. The hot magma that may be in an area pushes the older rocks (part of the plate) away from each other, causing a spreading motion.
Ocean Current.
They are called trenches.
The discovery of seafloor spreading provided evidence for the existence of tectonic plates. This process involves the movement of oceanic crust away from mid-ocean ridges, indicating that the Earth's lithosphere is composed of separate plates that are in motion. This discovery revolutionized our understanding of plate tectonics.
Oceanic trenches form where two tectonic plates converge, with one plate being forced beneath the other in a process known as subduction. This creates deep, narrow depressions in the ocean floor, some of which are the deepest parts of the ocean.
It is the converging boundaries of two tectonic plates, with one submerged under the other, this explains the trenches and the frequent seismic activity in the area (also know as the Ring of Fire).
Movement of the tectonic plates.
Deep ocean trenches can be formed by undersea earthquakes, land-slides, but also by the movement along the edges of tectonic plates.
Deep-ocean trenches are formed where seafloor tectonic plates subduct under continental plates.
They form by erosion, either from under water volcanos or the currents that constantly move the water. The point is they both cause trenches, also oceanic plate movement.
The Titanic plate movement refers to the process of one tectonic plate subducting beneath another plate in the Earth's lithosphere. This movement can lead to the formation of deep ocean trenches, volcanic arcs, and earthquakes along the boundaries of the plates.
Ocean Current.
what other ocean floor feature is fromed by movement of earth's plates
the ocean plates move because of the movement of the the tectonic plates beneath the ocean and do to the motion of the oceans currents.
They are called trenches.
Ocean trenches, volcanic arcs, mountains, uplands, and volcanic islands.
oceanic trenches occur where tectonic plates collide and one is pushed underneath the other.
