Are trenches formed at convergent or divergent?
No, ocean trenches do not occur at divergent plate boundaries. They are formed at convergent boundaries.
What occurs at a convergent plate boundary?
If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. The new magma (molten rock) rises and may erupt violently to form volcanoes, often building arcs of islands along the convergent boundary.
Are mid ocean trenches divergent or convergent?
Most of the Earth’s geologic activity takes place at plate boundaries. At a divergent boundary, volcanic activity produces a mid ocean ridge and small earthquakes. At a convergent boundary with at least one oceanic plate, an ocean trench, a chain of volcanoes develops and many earthquakes occur.
Can a divergent boundary form a trench?
A divergent boundary occurs when two tectonic plates move away from each other. The impact of the colliding plates can cause the edges of one or both plates to buckle up into a mountain ranges or one of the plates may bend down into a deep seafloor trench.
Do trenches form at convergent boundaries?
In particular, ocean trenches are a feature of convergent plate boundaries, where two or more tectonic plates meet. At many convergent plate boundaries, dense lithosphere melts or slides beneath less-dense lithosphere in a process called subduction, creating a trench.
How are ocean trenches a feature of convergent plate boundaries?
In particular, ocean trenches are a feature of convergent plate boundaries, where two or more tectonic plate s meet. At many convergent plate boundaries, dense lithosphere melts or slides beneath less-dense lithosphere in a process called subduction, creating a trench.
How is an ocean trench similar to a subduction zone?
Ocean-Ocean. The features of a subduction zone where an oceanic plate subducts beneath another oceanic plate are the same as a continent-ocean subduction zone. An ocean trench marks the location where the plate is pushed down into the mantle. In this case, the line of volcanoes that grows on the upper oceanic plate is an island arc.
How is a divergent boundary different from a convergent boundary?
Divergent boundaries are boundaries where plates pull away from each other, forming mild earthquakes and volcanoes as magma comes to the surface. Convergent boundaries are boundaries where two plates are pushing into each other.
How is the ocean trench related to the mantle?
An ocean trench marks the location where the plate is pushed down into the mantle. In this case, the line of volcanoes that grows on the upper oceanic plate is an island arc. Do you think earthquakes are common in these regions ( Figure below )?
