I am pretty sure it was formed from an underwater volcano but maybe you shouldn't trust me, I am only a kid and I am sort of guessing.
New crust is formed at a divergent boundary
Divergent Boundary, (Constructive Boundary).
No. New oceanic crust is formed at a divergent boundary. A convergent boundary neither creates nor destroys crust.
It creates a divergent boundary.
This would be called a Spreading center, or a divergent plate boundary.
Older material
A divergent boundary is formed when magma rises to the surface and new crust is formed. This process occurs at mid-ocean ridges where tectonic plates move away from each other, allowing magma to fill the gap and solidify into new oceanic crust.
because the molten rock cools in the water and forms a oceanic crust
No, subduction zones are where tectonic plates collide and one plate is forced beneath the other. New crust is formed at divergent plate boundaries, where plates move apart and magma rises to create new crust.
Divergent plate boundary.
the two plates are moving away from each other, and new crust is formed.
New crust is formed from rising magma at divergent plate boundaries.
