Tectonic Plate Motion Oceanic-Continental Plate Convergence. When an oceanic plate collides with a continental plate the crust forming the oceanic plate gets bent and pulled under the continental crust. This is because the rocks that form the oceanic crust are denser and thinner than the rocks that form the continental crust. The process by which the oceanic crust is pulled under the continental crust is called subduction and the zone at which this occurs at the plate boundaries is called the subduction zone. At the subduction zone where the oceanic crust sinks beneath the continental crust a deep oceanic trench or valley is created.

- In a subduction zone, the subducting plate, which is normally a plate with oceanic crust, moves beneath the other plate, which can be made of either oceanic or continental crust. During collisions between two continental plates, large mountain ranges, such as the Himalayas are formed.Oceanic-continental.s a result of pressure, friction, and plate material melting in the mantle, earthquakes and volcanoes are common near convergent boundaries. When two plates move towards one another, they form either a subduction zone or a continental collision.

- Where two tectonic plates converge, if one or both of the plates is oceanic lithosphere, a subduction zone will form. An oceanic plate will sink back into the mantle. Remember, oceanic plates are formed from mantle material at midocean ridges.

- Convergent Boundaries Places where plates crash or crunch together are called convergent boundaries. Plates only move a few centimeters each year, so collisions are very slow and last millions of years. Even though plate collisions take a long time, lots of interesting things happen. For example, in the drawing above, an oceanic plate has crashed into a continental plate. Looking at this drawing of two plates colliding is like looking at a single frame in a slow-motion movie of two cars crashing into each other. Just as the front ends of cars fold and bend in a collision, so do the front ends of colliding plates.

How do movements of tectonic plates affect the surface of earth? Subduction Plates: When one continental plate and one oceanic plate collide, the more dense oceanic plate is subducted or pushed under the continental plate. As it plunges deeper into the mantle, the rock of the oceanic crust melts, becoming part of the mantle.

Explanation on oceanic oceanic convergence? Oceanic-oceanic plate convergence also results in the formation of undersea volcanoes. Over millions of years, however, the erupted lava and volcanic debris pile up on the ocean floor until a submarine volcano rises above sea level to form an island volcano.est Answer: When two oceanic plates converge one is usually subducted under the other and in the process a deep oceanic trench is formed.

What happens when 2 oceanic plates diverge? Best Answer: When two oceanic plated diverge (move apart), a constructive or divergent plate margin/boundary is formed. Here, as the plates move apart, a gap is created in the crust, so magma from the mantle rises to the surface to fill this gap, forming a volcano. These volcanoes tend to be non-violent in nature.

- This usually involves a continental plate and an oceanic plate. The oceanic plate is denser than the continental plate so, as they move together, the oceanic plate is forced underneath the continental plate. The point at which this happens is called the subduction zone.As the oceanic plate is forced below the continental plate it melts to form magma and earthquakes are triggered. The magma collects to form a magma chamber [magma chamber: A region under the surface of the Earth where hot molten magma collects. ] .This magma then rises up through cracks in the continental crust.As pressure builds up, a volcanic eruption may occur. The diagram below shows how the oceanic plate is pushed underneath the continental plate, causing mountains and possibly volcanoes to form along the destructive plate boundary. . This magma then rises up through cracks in the continental crust. As pressure builds up, a volcanic eruption may occur.

Convergent plate boundaries Oceanic vs. oceanic plate convergence In a contest between a dense oceanic plate and a less dense, buoyant continental plate, you know that it’s the dense oceanic plate that sinks. What happens when two dense oceanic plates collide? Once again, density is the key!

Convergent Boundary Subduction zones. Subduction zones form when an oceanic plate collides with another oceanic plate or continental plate. The continental crust is lighter and less dense than oceanic crust. Continental crust's density is approximately 2.7 grams per cubic centimeter. Oceanic crust is thinner and the average density is about 3.3 cubic centimeters. When the two crustal plates converge the oceanic plate always bends and subducts beneath a continental plate.

Plate Boundaries When two plates converge, the result is called a collision. collide, the density of the plates determines which one comes out on top. Oceanic crust is more dense than continental crust. less dense dives under the other plate and returns to the mantle.

- When plates collide, earthquakes and volcanic activity occur. In geological time, collisions uplift mountain chains. Canada’s west coast is situated in one of the world’s most active collision zones, where the westbound North American plate overrides the Pacific plate.

- Crust is destroyed at the convergent plate boundary. This is usually between the oceanic and continental plates. This is where subduction of the more dense crust occurs.

- Crust here is neither created or destroyed. Continental-Oceanic and Oc … eanic-Oceanic collision bounsdaries generally lead to the formation of a subduction zone, where the denser plate (usually the older and therefore cooler oceanic plate) sinks back into the mantle and melts so is destroyed (or more accurately recycled).

Tectonic Plate Motion Oceanic-Oceanic Plate Convergence. This is similar to oceanic-continental convergence in that one of the plates is subducted under the other during the collision. At the subduction zone a very deep trench is formed in the ocean floor.Oceanic and oceanic plate convergence result in the formation of volcano chains. The crust that is pulled under or subducted melts to form magma. This magma rises to the top of the overriding oceanic plates and erupts on the ocean floor.t the subduction zone a very deep trench is formed in the ocean floor.

When plates move past each other 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. 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.

High School Earth Science/Theory of Plate Tectonics When two oceanic plates converge, the older, denser plate will sink beneath the other plate and plunge into the mantle. As the plate is pushed deeper into the mantle, it melts, which forms magma. As the magma rises it forms volcanoes in a line known as an island arc, which is a line of volcanic islands (Figure 6.21).

What are two bad things that can happen because of plate tectonics and how do the plates cause these things to happen? When plate tectonics collide they pressure against each other which can cause an earthquake or the plate tectonics can start to move up with each other and cause a volcano. When plate tectonics collide they pressure against each other which can cause an earthquake or the plate tectonics can start to move up with each other and cause a volcano. And the volcano would erupt because of the convention current.

- The edge of the continental plate in the drawing has folded into a huge mountain range, while the edge of the oceanic plate has bent downward and dug deep into the Earth. A trench has formed at the bend. All that folding and bending makes rock in both plates break and slip, causing earthquakes.

Convergent Boundary Colliding Plates Subduction zones form when a continental plate is colliding with an oceanic plate. Subduction zones also form when two oceanic plates collide. The continental crust is lighter because of the quartz and feldspar minerals in granite.hen the two plates meet the oceanic crustal plate always subducts beneath the continental plate. The subducting oceanic plate bends and plunges beneath the lighter continental plate until it melts. When two oceanic plates meet and form a subduction zone the heavier and denser of two oceanic plates subducts.

3.6 Destructive plate boundaries, continued: ocean-continent (Andean type) subduction Plate Tectonics. 3.6 Destructive plate boundaries, continued: ocean-continent (Andean type) subduction. When an oceanic plate converges with a continental plate, it is always the ocean plate that subducts beneath the continental plate. Continental lithosphere lies at a higher surface elevation than oceanic lithosphere because of its lower overall density.
