When does a plate carrying continental crust converges with a plate carrying oceanic crust?
When a plate carrying continental crust converges with a plate carrying oceanic crust, the denser oceanic plate is typically subducted beneath the less dense continental plate. This can lead to the formation of volcanic arcs and deep ocean trenches.
Why is the oceanic plate subducted when an oceanic plate collides with a continental plate?
The Oceanic plate is subducted under the Continental plate because oceanic crust is much more dense than continental crust. The average density of the oceanic crust is 3g/cm^3 while the average density of continental crust is 2.7g/cm^3.
Why are continental volcanoes associated with oceanic continental convergent boundaries?
Continental volcanoes form at oceanic-continental convergent boundaries because as oceanic plates are subducted beneath continental plates, the subducted oceanic crust melts due to the high temperatures and pressures deep within the Earth. This molten rock then rises to the surface, resulting in volcanic eruptions on the continental plate.
When a more dense oceanic plate sinks under continental plate?
This is called a destructive plate boundary. It occurs due to the fact that the oceanic crust is far denser than the continental crust. As a result it subducts into the mantle and is incenerated. Hope it helped:)
Why does the oceanic sink beneath continental crust at convergent boundaries?
The continental crust is less dense than the oceanic crust. That's the reason we find that the oceanic crust sinks (subducts) beneath the continental crust.Continental crust is less dense than oceanic crust and so cannot sink below it.
What do one oceanic and one continental crust produce when the oceanic crust is subducted under the continental one?
A trench and a strata volcano.
Why is oceanic crust always subducted underneath the continental crust?
Oceanic crust is denser and thinner than continental crust, making it more likely to be subducted beneath the less dense continental crust. This process occurs because the denser oceanic crust is pulled downward into the mantle at convergent plate boundaries due to gravitational forces. The subduction of oceanic crust beneath continental crust helps to recycle Earth's materials and plays a key role in plate tectonics and the geologic cycle.
Why oceanic crust is always subducted underneath continental crust?
Oceanic crust is denser than continental crust, so when they collide, the denser oceanic crust is forced beneath the lighter continental crust in a process known as subduction. This subduction occurs at convergent plate boundaries where two plates are moving towards each other. The sinking oceanic crust can trigger volcanic activity and create mountain ranges on the continental crust.

Convegent boundarie what changes to the crust occur?
The crust is compressed into mountains (if it is continental crust) or subducted back into the mantle if it is oceanic crust.
Why is oceanic crust younger than the continental crust?
oceanic crust is constantly being subducted and replaced with new material at places like the mid Atlantic ridge.
Why is the oldest oceanic crust is considerably than the oldest continental rock?
Oceanic crust is more dense than continental crust. As a result, over time, continental crust is harder to "recycle". Rocks are recycled when they are subducted and remelted. Since continental crust is harder to subduct (it wants to keep floating), it is not recycled as much as oceanic crust, which is dense and will sink and remelt.
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 with a plate of oceanic crust collides with a plate of continental crust?
The oceanic plate is made of denser (and thinner) rock than the continental crust, so the oceanic plate gets subducted (pushed underneath) where it descends and gets melted by geothermal heat.
