Answer :
Divergent plate boundaries are formed due to the movement of the tectonic plates. It justifies the formation of the oceanic floors by the plate tectonic theory.
What is plate tectonic theory?
Plate tectonic theory explains the formation of the landforms by the divergent, convergent, and transformation in the plate boundaries.
The divergent plate tectonic movement causes the formation of the basin ranges as the tectonic moves away from each other and supports the formation of the oceans.
Therefore, the plate tectonic theory supports ocean formation by the divergent plate boundaries.
