When An Oceanic Plate And A Continental Plate Collide What Is The Resulting Feature??
When an oceanic plate converges with a continental plate the oceanic crust will always subduct under the continental crust this is because oceanic crust is naturally denser. Convergent boundaries are commonly associated with larger earthquakes and higher volcanic activity.Nov 6 2020
When an oceanic and continental plate collide what is the resulting feature?
Plates Subduct 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.
When oceanic plates collide against a continental plate it will?
At convergent boundaries where plates push together crust is either folded or destroyed. When two plates with continental crust collide they will crumple and fold the rock between them. A plate with older denser oceanic crust will sink beneath another plate.
What happens when an oceanic plate collides with a continental plate quizlet?
When two oceanic plates collide the denser plate is subducted and some material rises upward and forms an ISLAND. What happens when two continental plates collide? The continental crust is pushed together and upward to form large MOUNTAIN ranges. … Ocean floor is pushed away from a midocean ridge to form new sea floor.
What happens when oceanic plates collide?
What happens when two plates collide?
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.
What type of plates collide in oceanic oceanic convergence?
An oceanic convergent plate boundary forms where two plates collide. In these collisions one plate sinks beneath the other. A subduction zone forms along the boundary where the denser plate sinks into the mantle and is heated causing plumes of molten magma to rise upward through the top plate.
When the oceanic plate hits a continental one the continental plate?
Generally when the oceanic plate hits a continental one the continental plate uplifts and the oceanic plate goes beneath it or subducts. When two oceanic plates collide the older heavier plate usually subducts beneath the other.
What happens when two continental plates transform?
When oceanic or continental plates slide past each other in opposite directions or move in the same direction but at different speeds a transform fault boundary is formed. No new crust is created or subducted and no volcanoes form but earthquakes occur along the fault.
When a continental plate and an oceanic plate collide they can form quizlet?
When 2 continental plates collide neither sink because they both have similar density in each. They will form mountain ranges. When both a oceanic and continental collide the oceanic plate will subduct under the continental because it is more dense a deep sea trench will usually form.
What happens when two continental plates collide quizlet?
a collision between two continental plates crunches and folds the rock at the boundary lifting it up and leading to the formation of mountains and mountain ranges.
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 happens in continental continental convergence?
What geologic feature is formed when two oceanic plates collide?
When two oceanic plates converge both a trench and a string of volcanoes are formed. These volcanoes can build to produce island chains such as the Mariana Islands which are located alongside the Marianas Trench.
How are oceanic oceanic and oceanic continental convergent boundaries different?
The oceanic plate is pushed under the continental plate and melted. … Continental plates are much thicker that Oceanic plates. At the convergent boundaries the continental plates are pushed upward and gain thickness. The rocks and geological layers are much older on continental plates than in the oceanic plates.
When two tectonic plates collide the continental crust usually rise up over the oceanic crust?
Oceanic crust is typically denser than continental crust and is forced downwards into the hot mantle when it collides with continental crust. The less dense conitinental crust is forced upward. This occurred in Ireland with the closure of the Iapetus Ocean over 450 million years ago.
What is oceanic oceanic convergence?
What happens when oceanic and continental crusts interact?
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 (figure 6). The entire region is known as a subduction zone. Subduction zones have a lot of intense earthquakes and volcanic eruptions.
Can oceanic and continental plates diverge?
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?
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.
What are geologic features?
When the oceanic and continental Lithospheres collide?
When oceanic lithosphere and continental lithosphere collide the dense oceanic lithosphere subducts beneath the less dense continental lithosphere. An accretionary wedge forms on the continental crust as deep-sea sediments and oceanic crust are scraped from the oceanic plate.
What features would you expect to find at an ocean continent convergent plate boundary?
At a convergent plate boundary when one plate is oceanic there are large volcanoes. These volcanoes are found in lines that outline the subduction zone. Earthquakes also happen in these zones. The Aleutian Islands that border southern Alaska are an island arc.
What does a convergent ocean ocean plate collision makes?
Convergent plate boundaries are locations where lithospheric plates are moving towards one another. The plate collisions that occur in these areas can produce earthquakes volcanic activity and crustal deformation.
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 the result of divergent boundary at two oceanic plates?
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.
What two geologic features are a result of divergent plates?
Effects that are found at a divergent boundary between oceanic plates include: a submarine mountain range such as the Mid-Atlantic Ridge volcanic activity in the form of fissure eruptions shallow earthquake activity creation of new seafloor and a widening ocean basin.
