Answer:

Answer:
Sea floor spreading
Explanation:
Sea floor spreading results in the formation of the oceanic basin.
After water has filled the basin, the sea floor begins to spread and move apart creating the ocean crust and its basins.
These are all due to different plate interactions within the earth.
After the crust has formed and filled with water, at divergent margins, new ocean floors are formed by volcanic activities at spreading centers.
The new crust is produced near the margin and subsequent ones push against it and away. The formation of new ocean floors product ocean basins.
