Responses

a plate of oceanic crust is subducted under a plate of continental crust
two plates of oceanic crust pull away from each other
two plates of oceanic crust pull away from each other
two plates of continental crust slide past each other
two plates of continental crust slide past each other
a plate of continental crust collides with another plate of continental crust
a plate of oceanic crust is subducted under a plate of continental crust
The correct statement that accurately describes how ocean trenches form is:
A plate of oceanic crust is subducted under a plate of continental crust.
The correct answer is: a plate of oceanic crust is subducted under a plate of continental crust.
Explanation:
Ocean trenches are formed at subduction zones, where one tectonic plate is forced underneath another. In the case of ocean trenches, a denser oceanic plate is being subducted under a less dense continental plate. This process occurs over millions or billions of years as the oceanic crust sinks into the mantle. The subduction of the oceanic crust leads to the formation of deep ocean trenches.
