What boundary is characterized by volcanic arcs and deep ocean trenches?
Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries. Volcanoes are one kind of feature that forms along
convergent plate boundaries
, where two tectonic plates collide and one moves beneath the other.
Which type of plate boundary is characterized by arcs of Stratovolcanoes and deep ocean trenches?
Which type of plate boundary is characterized by arcs of Stratovolcanoes?
Oceanic-continental plate boundaries
: if the subducting plate subducts beneath continental lithosphere, then a similar belt of volcanoes will be generated on the continent. These are called volcanic arcs
What type of plate boundary is associated with deep ocean trenches quizlet?
Where does a Deep-Ocean Trench occur?
A convergent plate boundary where one continental plate and one oceanic plate collide
. What happens at a Deep-Ocean Trench? You just studied 22 terms!
Which type of plate boundary is where lithosphere is sinking into the mantle?
Subduction zones
are where the cold oceanic lithosphere sinks back into the mantle and is recycled. They are found at convergent plate boundaries, where the oceanic lithosphere of one plate converges with the less dense lithosphere of another plate.
Which type of plate boundary is characterized by seafloor spreading which erupts Basalt Group of answer choices?
Mid-ocean ridges occur along
divergent plate boundaries
, where new ocean floor is created as the Earth’s tectonic plates spread apart. As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt.
Do convergent boundaries cause volcanoes?
Destructive, or convergent, plate boundaries are where the tectonic plates are moving towards each other. Volcanoes form here in two settings where either oceanic plate descends below another oceanic plate or an oceanic plate descends below a continental plate.
What is the example of divergent boundary?
A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust.
The Mid-Atlantic Ridge
is an example of divergent plate boundaries.
Is the Mariana Trench a divergent boundary?
It is separated from the Philippine Sea Plate to the west by a
divergent boundary
with numerous transform fault offsets. The boundary between the Mariana and the Pacific Plate to the east is a subduction zone with the Pacific Plate subducting beneath the Mariana.
What is the difference between a ridge and a trench?
Trench: very deep, elongated cavity bordering a continent or an island arc; it forms when
one tectonic plate slides
beneath another. Ridge: underwater mountain range that criss-crosses the oceans and is formed by rising magma in a zone where two plates are moving apart.
At what type of boundary do deep ocean trenches form?
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.
What type of plate boundary is a volcanic arc associated with?
When two oceanic plates collide against each other, the older and therefore heavier of the two subducts beneath the other, initiating volcanic activity in a manner similar to that which occurs at an
oceanic-continental convergent plate boundary
and forming a volcanic island arc.
What is created of a continental plate and an oceanic plate collide quizlet?
What forms at a convergent plate boundary when an oceanic plate collides with a continental plate?
Volcanoes and a trench are formed
.
How volcanic arc are formed?
Beneath the ocean, massive tectonic plates converge and grind against one another, which drives one below the other.
What happens when two oceanic plates collide?
When an ocean plate collides with another ocean plate or with a plate carrying continents,
one plate will bend and slide under the other
. This process is called subduction. A deep ocean trench forms at this subduction boundary.
In what type of plate boundary did new crust form?
Divergent boundaries
occur along spreading centers where plates are moving apart and new crust is created by magma pushing up from the mantle.
