What is the process by which oceanic crust sinks beneath the trenches?
Oceanic crust sinks beneath trenches through a process known as subduction. As oceanic plates collide with continental plates, the denser oceanic plate is forced downward into the mantle due to gravitational pull. This creates a subduction zone where the oceanic crust eventually melts and is recycled back into the mantle.
When continental crust and oceanic crust collide which one will subduct?
Oceanic crust is denser than continental crust, so when they collide, the oceanic crust will subduct beneath the continental crust. This subduction process can lead to the formation of volcanic arcs and mountain ranges.
What are the differences between oceanic crust and continental crust in age terms?
Overall their materials are of the same age, but the continental plates simply break or collide whereas the ocean-floor plates are in constant cycles of construction and destruction.
When continental crust and oceanic crust collide what happens?
When continental crust and oceanic crust collide, the denser oceanic crust is usually subducted beneath the less dense continental crust. This can create deep ocean trenches, volcanic arcs, and mountain ranges. The subduction of oceanic crust can also lead to the formation of earthquakes and volcanic activity.
What are 3 types of convergent pate boundaries?
Oceanic-continental plate boundary: where an oceanic plate and a continental plate collide, causing the oceanic plate to subduct beneath the continental plate. Oceanic-oceanic plate boundary: occurs when two oceanic plates collide, with one plate usually subducting beneath the other. Continental-continental plate boundary: where two continental plates collide, leading to the formation of mountain ranges through intense compression and uplifting of the crust.
When continental plates collide what happens to the oceanic crust between them?
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.
What happens to Rocks when plates collide?
When two plates collide, or come together, the plates will push upward, forming a mountain. If one plate is continental crust and the other is oceanic crust, the less dense crust (this being the oceanic) will actually move under the more dense crust, in a process called subduction, to form a deep-ocean trench.
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 to plates collided?
When two plates collide, or come together, the plates will push upward, forming a mountain. If one plate is continental crust and the other is oceanic crust, the less dense crust (this being the oceanic) will actually move under the more dense crust, in a process called subduction, to form a deep-ocean trench.
What is the difference between continentalcrust and the oceanic?
Continental crust is thicker and less dense while oceanic crust is thinner and more dense, so essentially continental crust takes a higher position than oceanic crust. When oceanic and continental plates collide, oceanic plates slide underneath continental plates(if this makes what I said any clearer).
Describe what happens when two plates carrying oceanic crust collide?
Best Answer:When two plates carrying oceanic crust collide, the resultis that one goes underneath the other - probably causinga tsunami - or an underwater earthquake.
Plate with oceanic crust sinking under another plate with oceanic crust?
When two oceanic plates or two plates both containing oceanic crust collide or converge, the convergent boundary will form a trench. The plate which has the higher density will plunge beneath the other plate forming a trench.
When two geologic plates are moving away from each other what happens?
When it is two continental plates, new oceanic crust is formed, and when this continues, more oceanic crust is formed between the plates.
What is the process by which oceanic crust sinks beneath the trenches?
Oceanic crust sinks beneath trenches through a process known as subduction. As oceanic plates collide with continental plates, the denser oceanic plate is forced downward into the mantle due to gravitational pull. This creates a subduction zone where the oceanic crust eventually melts and is recycled back into the mantle.
When two plates collide what determines which plate comes out on top?
The density of the plates and the angle of the collision can determine which plate comes out on top when two plates collide. The denser plate tends to sink beneath the less dense plate, while the angle of collision can influence the direction of movement. Additionally, the presence of features like oceanic crust and continental crust can also impact which plate is subducted.
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 when an oceanic crust colides with another oceanic crust?
The younger of the two plates, because it is less dense,* will ride over the edge of the older plate.
