New floor forms and spreads from mid-ocean ridges
No. Seafloor spreading occurs at a divergent boundary.

Yes. Seafloor spreading is the term given to the creation of new seafloor at divergent boundaries. At a divergent boundary, two oceanic plates move apart, which obviously means that something must then surface to fill the void. This is where the magma rises from the Earth's interior and cools to become seafloor. On the other end, at convergent boundaries, the old seafloor is forced under the continental plates, where it is recycled back into the Earth's magma supply.

usually from lava sinking to ocean floor and cooling.

The ages of the rocks become older the farther the way they are from the ridges. The closer they are the younger it is. This leaves evidence to the seafloor spreading theory.

Convergence supports the theory of seafloor spreading. Samples of the deep ocean floor are evidence of seafloor spreading because the basaltic oceanic crust and overlapping sediment become younger as the mid-ocean ridge is approached. Also, the rock that makes up the floor of the ocean is younger than the continents.

Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. Seafloor spreading helps explain continental drift in the theory of plate tectonics.
Seafloor spreading where new floor is formed. Subduction zone where older floor is pushed back into the mantle.
No. Seafloor spreading occurs at a divergent boundary.
It is called Seafloor Spreading, which comes under the Divergent Plate Movement.
