What are the consequences of convergent oceanic and continental plates?
Effects of a convergent boundary between an oceanic and continental plate include: a zone of earthquake activity that is shallow along the continent margin but deepens beneath the continent, sometimes an ocean trench forms immediately off shore of the continent, a line of volcanic eruptions a few hundred miles inland …
When two oceanic plates come together A is formed quizlet?
When two oceanic plates collides, they will form a volcanic island arc. This also forms a subduction zone. This is happening at the Aleutian Islands close to Alaska. Boundary between tectonic plates in which the two plates move away from each other, and new crust is created between them.
What forms when an oceanic plate and a continental plate converge *?
When oceanic crust converges with continental crust, the denser oceanic plate plunges beneath the continental plate. This process, called subduction, occurs at the oceanic trenches. … Subduction of an oceanic plate beneath a continental plate causes earthquakes and forms a line of volcanoes known as a continental arc.
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 makes continental plates different than oceanic plates quizlet?
Oceanic plates are where there is tectonic plates that are dencer than continental tectonic plate(s). Continental plates are where there is tectonic plate that are lighter than oceanic tectonic plate(s). …
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.
Is a defining feature of an oceanic plate?
Oceanic plates are mafic in nature, composed of basalt rock and its coarse-grained equivalent, gabbro, both rich in iron, magnesium and calcium. In contrast, continental plates are felsic in nature, dominated by granitic rock with its abundant silica, aluminum, sodium and potassium.
Which of the following is formed in the convergence of two oceanic or oceanic and continental plates?
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.
