What happens when a plate of oceanic crust collides with a plate of the continental crust and why does this happen?
The oceanic crust will slide under the continental crust. And the reason is because the oceanic crust is much denser and the continental crust is least dense.
How do the densities of oceanic crust and continental crust influence what happens when an oceanic plate coverages with a continental plate?
Oceanic crust is more dense than continental crust. All that water weight compresses the heck out of the material in the plate and also the oceanic crust contains larger percentages of denser elements such as magnesium and iron than the continental crust which also contributes to it's higher density. This sets the conditions for what happens. The more dense oceanic crust will "dive under" continental crust because it is more dense, and all because of the difference in densities.
What happens during subduction?
Dense oceanic crust slides under less dense continental crust
What happens at a destructive margin?
A destructive margin is when the oceanic crust moves towards the continental crust and slip under it (oceanic crust is heavier than the continental crust). This can build up a lot of pressure between the plates.
What layer of crust averages 25 miles in thickness?
Continental crust.
What is a characteristic of subduction?
The correct answers are - B. Where oceanic crust meets continental crust, and C. Earthquakes.Subduction zones appear only on places where a crust of lower density (oceanic crust) meets a crust of higher density (continental crust).On the places where the oceanic crust meets the continental crust, the oceanic crust goes beneath the continental crust, this makes changes and readjustments in the inner part of the crust, and plus there's significant pressure from the mantle layer from beneath, so earthquakes are a very common occurrence.Check all that apply. A. Broad river deltas B. Where oceanic crust meets continental crust C. Earthquakes D. Two continents collide
What happens when oceanic and continental crust meets?
Subduction. denser oceanic plate moves under the continental plate. The oceanic plate is submerged into the mantle causing magma to rise to the surface.
What are typical characteristics of subduction zone?
Where oceanic crust meets continental crust and earthquakes can occur.
What happens when a plate of oceanic crust collides with a plate of the continental crust and why does this happen?
The oceanic crust will slide under the continental crust. And the reason is because the oceanic crust is much denser and the continental crust is least dense.
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 to two oceanic crust when they collide?
the older crust is subducted and later pushed up to form oceanic arcs
What happens when the oceanic crust is increasing along mid-oceanic ridges?
when the crust increase the sea leavels beacem higher
What happens when oceanic crust sinks?
It turns into magma
What happens to mantle rock descending oceanic crust scrapes past continental crust?
The mantle rock descending from the oceanic crust causes the water in oceanic crust to be released. This lowers the melting point of the rock and causes it to melt.
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 to the leading edges of convergent plates as they collide?
This depends on what material (oceanic crust or continental crust) the leading edges are made of. When Continental crust hits Continental crust (eg India ploughing into Asia) the crust thickens by thrusting and folding and a mountain belt forms (the Himalayas). There is little or no volcanic activity associated with this sort of collision. When Oceanic crust meets Continental crust (eg the Pacific plate and the west coast of South America), the oceanic crust sinks below the continental crust forming an oceanic trench on the oceanic side (a subduction zone) and a mountain belt on the continental side (by folding and uplift). This sort of collision produces a large amount of volcanic activity. When Oceanic Crust meets Oceanic Crust, the actively spreading side sinks below the stationary side to form a back arc basin associated with island arcs and subduction zones (eg the Caribbean or the east of Papua New Guinea). This sort of collision also involves a large amount of volcanic activity.
