In 1960, seafloor spreading was hypothesized by Harry Hess of Princeton University. Seafloor spreading occurs at divergent boundaries and it is said to be the mechanism that operates along the oceanic ridge system to generate new seafloor. Thus, the result of seafloor spreading is the creation of new sea floor through the uplift of magma: magma raises from asthenosphere, new oceanic lithosphere moves from ridge, and it thickens, cools (becomes denser), and subsides.
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.
Mid-ocean ridge system.
The Mid Atlantic Ridge
Yes, also known as seafloor spreading! A rift zone volcano is called a mid-ocean ridge. The seafloor splits & spreads apart at a mid-ocean ridge, with lava seeping out of this fissure. The lava forms new seafloor. The older seafloor moves away from the ridge. Therefore, our ocean floor is actually spreading, at a rate of about two inches per year in the Atlantic ocean, and about 13 in the Pacific.
One example would be...the mid-atlantic ridge.

2. Mid Ocean Ridges are the place where new crust is formed. 1. oceanic plates or oceanic crust
Yes, the process that creates oceanic crust on a mid-ocean ridge is called "seafloor spreading". seafloor spreading creates a new oceanic crust that forms on the mid-ocean ridge.
