What are places where oceanic crust sinks back to the mantle?
No. Mid oceanic ridges are the places where new oceanic crust are forming.
Differences between oceanic-oceanic and oceanic-continental subduction boundary?
Oceanic to oceanic- one plate sinks under the other Oceanic- Continental ocean crust sinks under the other
What is the process by which oceanic crust sinks beneath the trenches?
Subduction.
What happens when an oceanic plate collides with a continental plate and sinks?
When the oceanic plate sinks it is absorbed back into the magma.
What are places where oceanic crust sinks back into the mantle called?
A "subduction zone".
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 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 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.
What are places where oceanic crust sinks back to the mantle?
No. Mid oceanic ridges are the places where new oceanic crust are forming.
Differences between oceanic-oceanic and oceanic-continental subduction boundary?
Oceanic to oceanic- one plate sinks under the other Oceanic- Continental ocean crust sinks under the other
Why does the continental crust float higher on the mantle than on the oceanic crust?
the oceanic crust is more dense therefore it sinks lower than continental crust
What is the process by which oceanic crust sinks beneath the trenches?
Subduction.
What are places where oceanic crust sinks back the the mantle?
A "subduction zone".
Where are the places where oceanic crust sinks back into the mantle.?
A "subduction zone".
What happens when oceanic plate and continental plate converge?
As oceanic crust is thinner, it sinks under the continental crust and forms a subduction zone. This can also form a line of volcanoes.a deep sea trench and an island arc form.
What happens when an oceanic plate collides with a continental plate and sinks?
When the oceanic plate sinks it is absorbed back into the magma.
What are places where oceanic crust sinks back into the mantle called?
A "subduction zone".
