Deep sea trenches are caused by one tectonic plate subducting under another. It is not the trenches which cause damage, it is the earthquakes caused by the subducting of one plate moving against the other.

How do ocean ridges and deep-sea trenches support the theory of sea floor spreading?

Ocean ridges and deep-sea trenches support the theory of sea floor spreading through the process of plate tectonics. At ocean ridges, new oceanic crust is formed as magma rises and solidifies, pushing the existing crust apart. Deep-sea trenches are areas where old oceanic crust is being subducted back into the mantle, completing the cycle of sea floor spreading. This continuous movement of crust at ridges and trenches provides evidence for the theory of sea floor spreading and the movement of tectonic plates.


What process produces deep sea trenches?

Deep sea trenches are formed at tectonic plate boundaries by the process of subduction. This occurs when one tectonic plate is forced beneath another plate, resulting in the formation of a deep trench in the ocean floor. Subduction zones are associated with intense geological activity and can also lead to the formation of volcanic arcs.


Are deep sea trenches vast underwater mountain chains?

No, deep sea trenches are not underwater mountain chains. Deep sea trenches are long, narrow depressions in the ocean floor formed by tectonic plate activity, while underwater mountain chains, known as mid-ocean ridges, are long mountain ranges on the ocean floor where tectonic plates are spreading apart.
