Why does oceanic lithosphere sink at subduction zones but not at mid ocean ridges?
Wiki User

oceanic lithosphere sinks at subduction zones but not at mid ocean ridges because at subduction zones the oceanic lithosphere is subducted, or sinks, under another plate. Oceanic Lithosphere sinks at subduction zones which are usually at convergent boundaries, but at mid-ocean ridges the plates are actually separating not coming together

Is new oceanic lithosphere is unable to form at mid-ocean ridges?
no
What are places where oceanic crust sinks back to the mantle?
No. Mid oceanic ridges are the places where new oceanic crust are forming.
What is the region where oceanic lithosphere sinks into the asthenosphere?
deep ocean trenches
What is the process by which plate tectonics produces new oceanic lithosphere at ocean ridges called?
Seafloor Spreading.
Mid-ocean ridges are actually underwater mountain ranges.?
It is true that mid-ocean ridges are underwater mountain ranges. These ridges are where the lithosphere is moving apart and new oceanic crust is being formed.

Where is lithosphere being consumed?
New oceanic lithosphere is constantly being produced at mid-ocean ridges and is recycled back to the mantle at subduction zones.
Where are oceanic crust and lithosphere formed?
At the mid-ocean ridges.
Is new oceanic lithosphere is unable to form at mid-ocean ridges?
no
What are places where oceanic crust sinks back to the mantle?
No. Mid oceanic ridges are the places where new oceanic crust are forming.
What is the region where oceanic lithosphere sinks into the asthenosphere?
deep ocean trenches
Deep ocean trenches are surficial evidence for?
Sinking of oceanic lithosphere into the mantle at a subduction zone.
What is the process by which plate tectonics produces new oceanic lithosphere at ocean ridges called?
Seafloor Spreading.
Mid ocean ridges are actually underwater mountain ranges?
It is true that mid-ocean ridges are underwater mountain ranges. These ridges are where the lithosphere is moving apart and new oceanic crust is being formed.
Are Mid-ocean ridges actually underwater mountain ranges?
It is true that mid-ocean ridges are underwater mountain ranges. These ridges are where the lithosphere is moving apart and new oceanic crust is being formed.

It is true that mid-ocean ridges are underwater mountain ranges. These ridges are where the lithosphere is moving apart and new oceanic crust is being formed.
Earth does not get bigger as new oceanic crust forms?
Just as new oceanic crust forms at mid-ocean ridges, old oceanic crust is destroyed at subduction zones.
