This occurs at an ocean trench (Figure below). Subduction zones are where subduction takes place. Subduction of an oceanic plate beneath a continental plate forms a line of volcanoes known as a continental arc and causes earthquakes.
What are the roles of oceanic plates?
Oceanic plates are formed by divergent plate boundaries. These zones, located along mid-ocean ridges, represent areas where upwelling magma creates new oceanic crust. As lava flows from these volcanic ridges, it quickly cools, forming extrusive igneous rock. … As oceanic plates subduct, they melt to form magma.
What do you think may happen to oceanic plate as it continues to move downward?
As it continues to move downwards, it will undergo subduction process. It will melt because of the very hot or high temperature of the mantle which is the layer below the crust.
When the oceanic and continental Lithospheres collide quizlet?
What happens when the oceanic and continental lithosphere collide? The oceanic plate subducts. You just studied 31 terms!
When oceanic lithosphere and continental lithosphere collide at convergent plate boundaries what may be formed?
A deep ocean trench forms. What happens when oceanic and continental lithosphere collide? Magma forms the asthenosphere cools to form new oceanic lothosphere.
Which of the following best describes what happens when an oceanic plate converges with a continental plate?
Which of the following best describes what happens when an oceanic plate converges with a continental plate? a trench and a mountain range with many volcanoes form. … Formed when an ocean basin between converging oceanic and continental plates is entirely subducted.
What is created when two oceanic plates converge?
Oceanic-oceanic convergence
As with oceanic-continental convergence, when two oceanic plates converge, one is usually subducted under the other, and in the process a trench is formed. … Subduction processes in oceanic-oceanic plate convergence also result in the formation of volcanoes.
What happens when two continental plates meet at a convergent boundary According to plate tectonics?
What happens when two continental plates meet at a convergent boundary according to plate tectonics? They push against each other to form deep-ocean trenches. They push against each other to form folded mountain ranges. … As any two plates meet at a fault line boundary, mountains are formed.
What happens when an oceanic plate meets another oceanic plate quizlet?
The oceanic plate is subducted. What happens when an oceanic plate meets another oceanic plate? The older, colder oceanic plate is subducted. … The two plates are forced upward, and a large mountain range is formed.
What will most likely happen in convergence of two oceanic plates?
If the two plates that meet at a convergent plate boundary both are of oceanic crust, the older, denser plate will subduct beneath the less dense plate. … The older plate subducts into a trench, resulting in earthquakes. Melting of mantle material creates volcanoes at the subduction zone.
What happens when two continental plates move towards each other?
When two plate move towards each other they converge or come together. The collision between two plates that are moving towards each other is called a convergent boundary. … The collision results in large damaging earthquakes. When two continental plates converge the result is the formation of large folded mountains.
When an ocean plate and a continental plate converge which plate will Subduct and why quizlet?
Since oceanic plates are denser than the continental plates, they will subduct to great depths when they converge with continental plates. When two oceanic plates converge, the denser of the two will subduct; whereas when two continental plates converge, neither will subduct.
When two tectonic plates collide the oceanic crust usually subducts beneath the continental Because?
Oceanic-Continental Subduction
An occurs when ocean crust sinks under continental crust, as shown in the diagram on page 636. The oceanic crust sinks because it is colder and denser than the continen- tal crust.
What geologic feature will be formed if the continents riding on top of two convergent collide?
When an oceanic plate meets a plate with a continent riding atop it, the oceanic plate is again subducted. When two continents meet, one is thrust over the other, and great mountain ranges like the Himalayas are formed.
Is the Antarctic plate oceanic or continental?
The Antarctic Plate includes continental crust making up Antarctica and its continental shelf, along with oceanic crust beneath the seas surrounding Antarctica.
