Deep-ocean trenches are formed where seafloor tectonic plates subduct under continental plates.
What else can I help you with?
Does theory continental drift state that new ocean crust is formed at ocean ridges and destroyed at deep sea trenches?
No, the theory is that Seafloor spreading state that the new ocean crust is formed at ocean ridges and is destroyed at deep sea trenches.
What make trenches in the ocean?
Deep ocean trenches can be formed by undersea earthquakes, land-slides, but also by the movement along the edges of tectonic plates.
How are trenches and mountains ranges connected?
Trenches and mountain ranges are both formed by tectonic plate movements. Trenches are formed where one tectonic plate is subducted under another, creating deep oceanic trenches. Mountain ranges are formed when tectonic plates collide, pushing up the Earth's crust to form high elevations.
In which ocean are most of the deep-sea trenches located?
Most of the deep-sea trenches are located in the Pacific Ocean. These trenches are formed by the subduction of tectonic plates, where one plate slides beneath another, creating deep underwater chasms. The Mariana Trench, the deepest known trench on Earth, is located in the Pacific Ocean.
What are formed along subduction zones?
Volcanic arcs and deep ocean trenches are formed along subduction zones. As one tectonic plate moves beneath another, the descending plate melts and creates magma that rises to the surface to form a volcanic arc. Deep ocean trenches are also created as the overriding plate bends and sinks into the Earth's mantle.
Does the theory of continental drift state that ocean crust is formed at ocean ridges and destroyed at deep sea trenches?
Yes
What ocean has many deep valleys or trenches?
Trenches
What produces deep sea trenches?
A process known as subduction creates deep sea trenches.
Where do giant squids live in deep oceans trenches or mid ocean trenches?
Giant squid primarily live in deep ocean trenches.
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.
What process produces deep-sea trenches?
A process known as subduction creates deep sea trenches.
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.
