a divergent plate boundary.
Ridges, parallel to the axis of spreading, are formed in the ocean floor as hot lava moves up to fill the gap then cools when it comes in contact with sea water.

Sea floor spreading occurs at the mid ocean ridges.
Sea floor spreading occurs at mid-ocean ridges
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.
One observation that was not instrumental in formulating the hypothesis of sea floor spreading is the distribution of terrestrial fossils across continents. While these fossils provided evidence for continental drift, they did not directly relate to the mechanisms of sea floor spreading, which is primarily supported by observations such as the age of oceanic crust, magnetic stripe patterns on the sea floor, and the presence of mid-ocean ridges.
Spreading Of ocean floor
sea-floor spreading
the sea floor is spreading about 3cm every year answers will vary but it is usually around 3cm
Sea floor spreading mean the process by which molten material adds new oceanic crust to the ocean floor
The presence of magnetic domains of alternating orientation parallel to the plate boundaries.
