at mid ocean ridges
Because diverging plate boundaries occur at mid-ocean ridges, this means the two lithospheric plates are spreading apart.
When tectonic plates move and grind against each other, this is an earthquake. If the moving of tectonic plates were to occur beneath the ocean's surface, the result would be a tsunami.
At spreading centers.
Mid-ocean ridges and trenches
The Ocean Plates Are Shifting
the moving of techtonic plates causes mountains and underneath the ocean they make trenches ect.
Plate tectonics, the moving and repositioning of earths plates.
oceanic trenches occur where tectonic plates collide and one is pushed underneath the other.
The Pacific Ocean is part of the Ring of Fire. The ring of fire is underwater trenches made my moving plates. The plates pushed on each other and eventually moved downward, creating trenches
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:)
Deep-ocean trenches are formed where seafloor tectonic plates subduct under continental plates.
Movement of the tectonic plates.
Because diverging plate boundaries occur at mid-ocean ridges, this means the two lithospheric plates are spreading apart.
Ocean trenches are the deepest parts of the ocean. They border continents or island arcs where tectonic plates come together.
Consider. In sea-floor spreading, the plates are spreading apart; in other words diverging. So sea-floor spreading occurs at a divergent boundary,
Deep ocean trenches are typically the evidence of the collision of tectonic plates. This collision is often known as subduction.
