When an oceanic and a continental plate collide, eventually the oceanic plate is subducted under the continental plate due to the high density of the oceanic plate . Once again a benioff zone forms where there are shallow intermediate and deep focus earthquakes.
When a continental plate collides with an oceanic plate the ocean plate is?
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 happen when two oceanic plates collide?
A subduction zone is also generated when two oceanic plates collide — the older plate is forced under the younger one — and it leads to the formation of chains of volcanic islands known as island arcs. ... Earthquakes generated in a subduction zone can also give rise to tsunamis.
What happens when two plates carrying oceanic crust collide?
When two plates carrying oceanic crust collide, the plate carrying older oceanic crust will be forced below the other in a process called subduction ....
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.
When an oceanic and continental crust collides what geologic feature is formed on the oceanic crust?
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.
When two oceanic plates collide what determines which plate Subducts?
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 .
What happens in continental continental convergence?
When two continental plates converge, they smash together and create mountains . The amazing Himalaya Mountains are the result of this type of convergent plate boundary.
What is the geologic features of oceanic oceanic?
There are many geologic features on the ocean floor. Trenches, ridges, rises, and islands are the result of continental or oceanic plate movement. Volcanic eruptions and earthquakes are also the result of tectonic plate movement.
When two plates with continental crust collide what happens to the continental crust?
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. The crust melts in the asthenosphere and is destroyed.
What happens when two plates carrying oceanic crust collide quizlet?
When two plates carrying oceanic crust collide the more dense crust sinks under the less dense one and creates a trench . When two continental plates collide they form mountain ranges and volcanoes.
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 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.
What forms when oceanic crust collides with continental crust?
Eventually, as continents congealed into smaller, thick plates, they would collide with newly created oceanic plates. These denser plates would subduct under the continental crust, and volcanoes would form.
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 is formed from the collision?
In order for a collision to be successful by resulting in a chemical reaction, A and B must collide with sufficient energy to break chemical bonds. This is because in any chemical reaction, chemical bonds in the reactants are broken, and new bonds in the products are formed.
What is oceanic continental convergent?
At an ocean-continent convergent boundary, the denser oceanic plate is pushed under the less dense continental plate in the same manner as at an ocean-ocean boundary. ... The magma produced adjacent to the subduction zone rises to the base of the continental crust and leads to partial melting of the crustal rock.
What is the geologic features present created of oceanic continental?
Subduction of an oceanic plate beneath a continental plate causes earthquakes and forms a line of volcanoes known as a continental arc. The movement of crust and magma causes earthquakes. Remember that the mid-ocean ridge is where hot mantle material upwells in a convection cell.
What are 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 oceanic plates subduct, they melt to form magma. This magma cools over millions of years, producing intrusive igneous rock and new continental crust.
What geologic feature is are formed in oceanic oceanic convergence?
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.
Which is formed when oceanic plate converges with another oceanic plate?
When two oceanic plates converge, the denser plate will end up sinking below the less dense plate, leading to the formation of an oceanic subduction zone . ... Whenever a subduction zone is formed, the subducted plate will end up being partially melted by the earth’s internal magma and molten.
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 .
When an oceanic plate meets a continental plate head on what occurs quizlet?
Occurs when an oceanic plate pushes into and subducts under a continental plate, the overriding continental plate is lifted up and a mountain range is created. Occurs when two continents meet head-on. The crust tends to buckle, crumple, and form mountains.
What geologic feature is created when an ocean plate converges with another ocean plate quizlet?
Volcanic Island Arcs – when two oceanic plates collide and one oceanic plate subducts under the other creating a dip into the mantle pulling magma creating volcanoes. What type of geological features are created by divergent boundaries of continental and continental plates? Rift Valleys are created at the boundary.
