In most ocean-continent collisions, the denser oceanic crust subducts beneath the lighter continental crust. This process leads to the formation of deep ocean trenches and volcanic arcs on the continental side. As the oceanic plate descends into the mantle, it melts and contributes to the formation of magma, which can result in volcanic activity. Over time, this subduction can also cause significant geological features and seismic activity in the region.
What else can I help you with?
What are the two types of crust and which rocks make up each crust?
there are two types of crust such as the oceanic crust and the continental crust, the oceanic crust is thinner and more dense than the continental crust and is constantly being recycled via subduction upon collisions with Continental crust, and creating at mid-ocean ridges. x
Which types of lithosphere are colliding with continent collisions?
In continent-continent collisions, the primary types of lithosphere involved are continental crusts. These collisions occur when two continental plates converge, leading to the formation of mountain ranges, such as the Himalayas, as neither plate is subducted due to their relatively similar densities. Additionally, oceanic lithosphere may also play a role in these tectonic interactions when it subducts beneath continental crust before the collision occurs, but the direct collision involves primarily continental lithosphere.
What happens to the old oceanic crust as new molten material rises from the mantle?
The older oceanic crust moves away from the spreading center and is eventualy subducted back into the mantle.
What happens to mantle rock descending oceanic crust scrapes past continental crust?
As the oceanic crust descends beneath the continental crust, the mantle rock is subjected to high pressure and temperature. This causes the mantle rock to partially melt, producing magma that can rise to the surface and form volcanoes. The interaction of the descending oceanic crust with the continental crust can also lead to earthquake activity.
What crust is more dense oceanic or continental crust?
Oceanic crust is significantly denser.
What means the ocean is pulled under the continent?
The ocean is never pulled under the continent. Oceanic crust--the rock and some sediments, however, slide under the edges of continental crust and are pushed downward toward the mantle in areas of oceanic to continental plate collisions.
The margin of a continent is the boundary between continental crust and?
oceanic crust
What happens when a heavier oceanic crust collides with a continental crust?
Trench
What happens when a plate of oceanic crust collides with a plate of Continetal crust why?
the oceanic crust slides down and burns in the mantle and forms a volcano
What happens when the oceanic crust is increasing along mid-oceanic ridges?
when the crust increase the sea leavels beacem higher
What happens to two oceanic crust when they collide?
the older crust is subducted and later pushed up to form oceanic arcs
What do you call the land under te ocean from which the continent rises?
Oceanic Crust
What happens when a plate of oceanic crust collides with a plate of the continental crust and why does this happen?
When oceanic crust collides with continental crust, the denser oceanic crust is forced beneath the continental crust in a process called subduction. This happens because oceanic crust is heavier, colder, and more dense than continental crust, making it susceptible to being subducted under the lighter continental crust. This collision can result in the formation of mountain ranges, volcanic arcs, and deep ocean trenches.
What happens when an oceanic and an oceanic plate collide?
since the oceanic crus is thinner than the Continental crust the oceanic crust get submerged and gets destroyed while the continental crust covers the submerged part as being taken over by continental crust....//\@Rtz Z@r...
What happens at an oceanic- oceanic subduction?
The plate with cooler, denser crust sinks under the other plate, forming a trench. There, the oceanic crust sinks down back into the mantle.
What happens at oceanic-oceanic subduction?
The plate with cooler, denser crust sinks under the other plate, forming a trench. There, the oceanic crust sinks down back into the mantle.
What happens when an oceanic plate collides with a continental plate?
when oceanic crust and continental crust collide, the oceanic crust sinks down beneath the continental crust. this is called subduction.
