Subduction. denser oceanic plate moves under the continental plate. The oceanic plate is submerged into the mantle causing magma to rise to the surface.
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.
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.
The oceanic crust begins at the Mid-Ocean Ridge, where tectonic plates are moving apart, allowing magma to rise and solidify, forming new crust. This process of seafloor spreading creates the youngest oceanic crust at the ridge and older crust farther away from it.
When continental plates collide, the denser oceanic crust is usually subducted beneath the less dense continental crust. This process can create subduction zones, where the oceanic crust is forced downward into the mantle. The oceanic crust may melt or be recycled back into the mantle in these subduction zones.
The lithosphere can have two main types of crust: continental crust and oceanic crust. Continental crust is thicker, older, and less dense than oceanic crust. Oceanic crust is thinner, younger, and denser, primarily composed of basaltic rocks.
Where oceanic crust meets continental crust and earthquakes can occur.
When oceanic and continental crust meet, a subduction zone is formed where the denser oceanic crust is forced beneath the less dense continental crust. This process typically results in the formation of deep ocean trenches, volcanic arcs, and earthquakes.
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
Trench
the oceanic crust slides down and burns in the mantle and forms a volcano
when the crust increase the sea leavels beacem higher
the older crust is subducted and later pushed up to form oceanic arcs

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...
The plate with cooler, denser crust sinks under the other plate, forming a trench. There, the oceanic crust sinks down back into the mantle.

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.
