Where are oceanic trenches?
plate tectonics
Deep-oceanic trenches are most abundant around the rim of the?
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.
Which can NOT form as the result of oceanic-oceanic convergence?
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.
What are the valleys under the ocean called?
They are called trenches.
How is the formation of mid-ocean ridges and trenches different?
Mid-ocean ridges form at divergent boundaries where tectonic plates are moving apart, allowing magma to rise from the mantle and create new oceanic crust. Trenches form at convergent boundaries where one plate subducts beneath another, creating deep oceanic trenches due to the sinking of the denser plate back into the mantle.
How does a deep-ocean trench form?
They form when the oceanic crust goes under the Continental crust. The oceanic crust then forms the trenches through a process called subduction.
What forms at a subduction zone?
Volcanic arcs and oceanic trenches commonly form at subduction zones.
How does trench formed?
They form when the oceanic crust goes under the Continental crust. The oceanic crust then forms the trenches through a process called subduction.

What does a convergant boundary form?
There are three types of convergent boundaries: Oceanic, continental, and continental-oceanic convergent boundaries. Continental-continental convergent boundaries form mountain ranges. Continental-oceanic boundaries result in subduction zones and the recycling of lithosphere. The continental side of the boundary may form a mountain range. Oceanic-oceanic form deep oceanic trenches and sometimes volcanoes.
What does the collision of a continental plate and an oceanic plate produce?
when two plates collide they form trenches.

Where do sea trenches form?
Sea trenches form at convergent plate boundaries where one tectonic plate is subducted beneath another. This typically occurs in regions where an oceanic plate collides with a continental plate or another oceanic plate. As the denser oceanic plate sinks into the mantle, it creates a deep, narrow depression in the ocean floor, resulting in a trench. The Mariana Trench is the most well-known example of this geological feature.
