An ocean because when the ocean spread out the ocean floor is moving and becoming large but because also of the sinking of the ocean floor it 's not becoming larger it's just maintaining it own size. lyssa

Sea floor spreading occurs at mid-ocean ridges.
Consider. In sea-floor spreading, the plates are spreading apart; in other words diverging. So sea-floor spreading occurs at a divergent boundary,
It occurs in the oceanic crust!!!
mantle
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.

The Super Continent was broken apart, in part by sea-floor spreading.Scientists discovered that sea-floor spreading continues to move the continents.Sea-floor spreading can be measured using specialized equipment.
