Older material
Divergent plate boundaries create new ocean crust.
This would be called a Spreading center, or a divergent plate boundary.

Divergent
Continental /Oceanic Crust is being formed.
Divergent: Created Collision\Subduction: Destroyed
Convergent boundary
New oceanic crust is being created at the mid-ocean ridges.
Subduction.
This would be called a Spreading center, or a divergent plate boundary.
2.) an ocean trench
The mid-ocean ridge is formed along a divergent or constructive plate boundary between two plates of oceanic crust.
The magma flows upward from the split in the crust caused by the boundary.

It indicates the presence of a divergent tectonic plate boundary where new crust is being formed.
A tectonic boundary where two oceanic lithospheric plates are either moving away from one another and new crust is formed, or moving toward each other, in which the more dense oceanic plate will subduct beneath the less dense plate.
No. As crust subducts under another plate, it is destroyed (Convergent Boundary). When plates pull apart, new crust is formed (Divergent Boundary).
Continental /Oceanic Crust is being formed.
The mid-ocean ridge is formed along a divergent or constructive plate boundary between two plates of oceanic crust. A classic example is the Mid-Atlantic Ridge where the Eurasian and African Plates are moving away from the North and South American Plates.
Oceanic crust is created at mid-ocean ridges and (through the creation of new oceanic crust) is pushed toward a convergent plate boundary where it is subducted. So the oldest oceanic crust would be located at a convergent plate boundary where the oceanic crust is being subducted under continental crust.
Mount Etna Was Formed By Destructive Plate Boundaries. This Is When One Crust Is Forced Under Another Crust. It Stands At The Convergent Boundary Where The African Crust Is Being Sub Ducted Beneath The Eurasian Crust. This Causes The Latter To Deform And Forces the Magma Up Into Weak Spots In The Earths Crust (mount Etna) When There Has Become To Much Of A Magma Build Up In The Mantle.
