How did the western cordillera form?
The Nasca plate drove under the Pacific plate.
When plate movements cause the crust to bend downward a what is formed?
When a plate is pushed under an adjacent plate, the process is called subduction. The subducted crust melts into the core and is recycled. When the plate goes into the mantel it is heated to very high temperatures and turns into metamorphic rock.
When two oceanic plates meet witch plate gets subducted and why?
When two oceanic plates meet, which plate gets subducted and why
Was Japan formed by the Pacific plate moving over the Eurasian plate?
Japan is a string of volcanic islands which are formed at a convergent-subduction boundary. In this case, the subducted island was the Pacific Plate. When the pacific plate was subducted, the crust heated to form magma and expanded, pushing the Eurasian Plate upwards. This new magma close to the surface began breaking through the surface and forming volcanoes which eventually became islands.
How are volcanoes formed by convergent plate boundaries?
Where one convergent plate is subducted under another, the sinking slab (which is full of wet sediments and organic remains) is heated and some of it melts to form magmas which migrate upwards to form volcanoes on the edge of the overlying plate.
Where does the oceanic crust eventually go?
It is subducted toward the core and eventually melts, forming magma.
What events can occur when plate move?
Volcanoes forming, Islands Forming, Deep Sea Trenches Forming, Earthquake Actvity, New oceanic crust forming, Old oceanic crust being subducted
How did the western cordillera form?

How does a plate tectonic have to do with a volcano?
Volcanoes tend to form on the land above an area where one techtonic plate is subducted beneath another. The eastern edge of the Pacific plate is being subducted under the South American plate. The subducted plate melts under the extreme pressure and temperature. The molten rock then works its way up through stress fissures, caused by the two plates colliding, to form volcanoes in the area above the subduction zone. This is why there are volcanoes along the length of the Andes.

What geological features are caused by a subduction?
When a plate is subducted under another the geological feature depends what type of plate boundary it is. If it is two oceanic plates then the subduction causes Island Arcs to be formed as well as a trenches. When a oceanic plate is subducted under a continental plate then a trench is again formed just off the shore of the continental plate and fold mountains are created as the continental plate is forced upwards and the friction melts the oceanic plate into magma which then rises (as it is less dense than surrounding magma) and forms volcanos.
What are two things that cold happen to a metamorphic rock to continue the rock cycle?
It could be weathered forming sediments, or it could be subducted at a plate margin, melt and form magma.
What builds up earths surface?
Earth's land surface is built up by a process called tectonic subduction.Related Information:This process occurs as one tectonic plate is subducted (slips under) another, while the subducting plate is elevated as it moves over the subducted plate. The subducted plate is most commonly a oceanic plate.
Where on earth is there an example of an oceanic plate going under a continental plate?
This phenomenon is called plate subduction and is seen in South America where the Nazca plate is being subducted under the South American plate. The Juan the Fuca plate is being subducted under North American plate.
