What happens when a plate carrying continental crust converges with a plate carrying oceanic crust?
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.
What happens when oceanic and continental plates diverge?
As plates made of oceanic crust pull apart, a crack in the ocean floor appears. The magma also spreads outward, forming new ocean floor and new oceanic crust. Rifts. When two continental plates diverge, a valleylike rift develops.
What happens when oceanic crust collides with continental crust at a plate boundary a the continental crust moves closer to the mantle B the ocean?
The process by which the ocean floor sinks beneath a deep-ocean trench and back into the mantle. What happens when oceanic crust collides with continental crust? Subduction occurs as the denser oceanic plate sinks beneath the less dense continental plate. Two plates move past each other, moving in opposite directions.
What happens when a continental crust collides with an oceanic crust?
When they collide, the Oceanic crust sinks below the continent. As it sinks, it heats up at the edge of the mantle and begins to melt.
What type of boundary destroys crust?
convergent boundaries
What are created by convergent boundaries?
At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.
What is an example of a continental divergent boundary?
Iceland is an example of a country undergoing a continental divergent boundary. The Mid-Atlantic Ridge divides Iceland and is the boundary between the North American and Eurasian tectonic plates. The East Africa Rift Valley is an example of a continental divergent boundary.
Which of the following is an example of a transform plate boundary?
The San Andreas Fault and Queen Charlotte Fault are transform plate boundaries developing where the Pacific Plate moves northward past the North American Plate. The San Andreas Fault is just one of several faults that accommodate the transform motion between the Pacific and North American plates.
What type of plate boundary does not cause volcanoes?
Volcanism occurs at convergent boundaries (subduction zones) and at divergent boundaries (mid-ocean ridges, continental rifts), but not commonly at transform boundaries.
