That's a hotly debated question among scientists. We do know that trenches form where oceanic lithosphere subducts under continental lithosphere. as to what drives the plates together, it is probably continents being moved by the currents of the partially liquified asthenosphere below it. Many scientists think that it is the weight of the oceanic lithosphere being pulled by gravity and pushed from the higher mid-ocean ridges. To me that seems a bit like a chihuahua pulling a house.
What else can I help you with?
Why do passive margins have no trenches?
Trenches are caused by plate movement.
Do Trenches occur at divergent plate boundaries.?
that is false
What does the theory of plate tectonics suggest about the creation of deep sea trenches?
The theory of plate tectonics suggests that deep sea trenches are formed at subduction zones, where one tectonic plate is forced beneath another. This process occurs as a result of the movement of tectonic plates, leading to the creation of deep sea trenches through the process of plate convergence.
What are some plate movement effects?
The movement of plate tectonics can result in earthquakes, tsunamis, mountain building, volcanic activity, and oceanic trenches.
What does the theory of plate tectonics suggest about the creation of deep-sea trenches?
The theory of plate tectonics suggests that deep-sea trenches are formed at subduction zones where one tectonic plate slides beneath another. This process occurs due to the movement of the Earth's lithosphere, leading to the formation of these deep topographic features.
WHAT ARE THE GEOLOGIC processes events that will occur because of this plate movement?
What are geologic processes/vents that will occur because of this plate movement?
What are 2 geological features that can occur at plate boundaries?
Two geological features that can occur at plate boundaries are mountain ranges, formed from the collision of two plates, and deep ocean trenches, formed at subduction zones where one plate is forced beneath another.
How does tectonic plate movement occur?
because
Where do ocean trenches occur?
At spreading centers.
What type of tectonic plate movement can cause the formation of mountains trenches or volcanoes?
weathering and erosion
Explain what plate tectonics and ocean trenches have in common?
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:)
Do Ocean Trenches Occur where plates are moving apart or where They are moving apart?
Ocean trenches occur where plates are moving towards each other and one plate is being pushed beneath the other in a process called subduction. Trenches are formed at convergent plate boundaries where oceanic crust is being forced downward into the mantle.
