What happens when a tectonic plate carrying oceanic crust collides with a tectonic plate carrying continental crust?
If the plates are moving at each other from directly opposite directions, the denser oceanic crust will subduct, or slide under the less dense continental crust, eventually melting back into the mantle. The hot gasses and pressure created by the melting process will seek release in the form of a volcano! :D
What happens if the tectonic plates are on top each other?
The lower plate subducts down into the mantle while frictional heating between the plates melts the rock of the plates, creating volcanoes in the upper plate.
What happens in a continental to oceanic plate collision?
The oceanic plate is forced below the continental, It sinks into the mantle. An oceanic trench is formed where it descnds. The plate melts as it sinks, due in part to friction between the plates. This produces earthquakes and volcanos, and as the magma tends to contain lots of volotiles, the volcanos are explosive.
What happens when two tectonic plates rub back and forth?
an earthquake happens
What happens to lithospheric plates at tectonic plate boundaries?
Divergent Plate Boundary: The area where two plates are moving in relatively opposite directions and new crustal material is being created by rising decompressed mantle rock. Examples would be the mid-ocean ridges, and the East African Rift. Convergent Plate Boundary: The area where two tectonic plates are moving toward each other and one of two things happens; either the more dense plate subducts under the lighter plate and heads toward the mantle, or, if the plates are of similar density, they cause uplift and mountain forming events. Examples would be the oceanic to continental crustal collision creating the Andes Mountains, and the continental to continental crustal collision creating the Himalayan Mountains. Transform Plate Boundary: The area where two plates are grinding past each other, snapping into place from elastic rebound as they go, causing numerous earthquakes. The San Andreas Fault is an example of a transform plate boundary between the North American and Pacific plates.
When the ocean floor collides with a crustal plate what happens?
it subducts underneath the crustal plate
What happens when a tectonic plate slides under another tectonic plate?
This happens at a plate boundary. The oceanic plate subducts (sinks) under the continental plate, because it is heavier. (the oceanic plate is made of basalt and the continental plate is made of granite.) This happens at a destructive plate margin. it is called this because part if the oceanic plate is destroyed, because it melts as it sinks.

When 2 plates diverge what happens?
The older denser plate subducts
What happens at a convergent tectonic plate boundary?
An ocean trench forms Two tectonic plates push against each other. The denser/heavier plate is pushed down under the other plate which is in turn pushed up to create mountains.
What happens tectonic plates come together?
Convergent plates are two tectonic plates that are colliding as they move toward each other. There are several types of converging plate boundaries.Oceanic to oceanic plate convergence:Where an oceanic plate collides with another oceanic plate, the more dense plate subducts into the mantle. The subduction results in the partial melting of lithospheric rock above the area of the subduction, causing underwater volcanoes to form. If the volcanoes grow to reach the surface, volcanic arc islands are formed.Oceanic to continental plate convergence:Where an oceanic plate collides with a continental plate, the oceanic plate is subducted due to the fact that it is more dense, which can also cause volcanism and mountain building.Continental to continental plate convergence:Where two continental plates collide, neither subducts into the mantle, the crust is thickened, and mountain ranges are formed from the thickening and uplift.
What happens under the earth?
Under the earth tectonic plates and continental plate is covered in earth crust . movement is happen due to mining andsoil dig due to devolepment purpose.
What happens when tectonic plates suddenly move?
An Earthquake happens.
What happens in a continental to oceanic plate collision?
The oceanic plate is forced below the continental, It sinks into the mantle. An oceanic trench is formed where it descnds. The plate melts as it sinks, due in part to friction between the plates. This produces earthquakes and volcanos, and as the magma tends to contain lots of volotiles, the volcanos are explosive.
What happens when continental and oceanic lithospheres collide?
When oceanic lithosphere and continental lithosphere collide, the continental lithosphere may be obducted over the oceanic lithosphere or the oceanic lithosphere may be subducted under the continental lithosphere. The latter is thought to be more common. This subduction and obduction generally results in tectonic activity such as volcanoes and earthquakes.
What happens when a plate gets subducted?
The colder, more dense plate is the one that subducts in a collision between two plates. In an oceanic to oceanic plate collision it is the older of the two plates that will subduct due to its higher density. In an oceanic to continental plate collision, it's the oceanic plate that will subduct because of its higher density.
