Because of plate tectonics. Because it's 2 plates underwater that are moving apart.
Magma rise up to where the 2 plates are separating to fill in the gap. Seafloor spreading occurs underwater.

What kind of boundary can sea floor spreading occur?
subducting
Does sea-floor spreading occur in oceans only?
It occurs in the oceanic crust!!!
In which layer do convection currents causing sea floor spreading occur?
mantle
At what boundary does sea-floor spreading occur?
Consider. In sea-floor spreading, the plates are spreading apart; in other words diverging. So sea-floor spreading occurs at a divergent boundary,
Where does sea flooring occur?
Sea floor spreading occurs at mid-ocean ridges.
Does sea floor spreading occur at a convergent boundary?
No, sea floor spreading does not occur at a convergent boundary. Sea floor spreading occurs at divergent boundaries where tectonic plates move away from each other, allowing magma to rise and create new oceanic crust. At convergent boundaries, two plates collide, leading to subduction or crustal deformation.
What is a spreading center on the ocean floor?
sea floor-spreading..;)
Another name for divergent boundaries that occur under the ocean is?
Sea floor spreading
