Divergent Boundary, (Constructive Boundary).
new crust is always being formed by magma erupting from volcanoes and then cooling into rock making new crust. -Jacob Halon
Seafloor spreading
No. New oceanic crust is formed at a divergent boundary. A convergent boundary neither creates nor destroys crust.
No. As crust subducts under another plate, it is destroyed (Convergent Boundary). When plates pull apart, new crust is formed (Divergent Boundary).
New crust is formed at a divergent boundary
This would be called a Spreading center, or a divergent plate boundary.

Since the rock just came up and cooled, it's "new oceanic rock." Because... it's new rock. It's the youngest rock. It just came out of the ground and cooled, making it rock. Or Because new crust is being formed while the old crust is being pushed away.

divergent
New oceanic crust is continually being created at the Mid-Ocean ridges.
That is correct.
