Continental drift is caused by lava pushing the seabed apart
the verdict
CONTESTED
the evidence cuts both ways
confidence 31/100
While volcanic activity and lava extrusion constantly shape the ocean floor at mid-ocean ridges, attributing continental drift and seafloor spreading purely to lava pushing apart the seabed oversimplifies complex geodynamic forces like plate tectonics, mantle convection, and lithospheric inheritance.

The paper discusses how new oceanic crust forms at mid-ocean ridges through continuous volcanic activity and lava emplacement along spreading axes.

Persisting influence of continental inheritance on early oceanic spreading.

The paper explains that early oceanic spreading and tectonic movements are influenced by long-term continental inheritance and lithospheric thickness variations rather than simple lava pushing.

Observations of volcanic edifices along the Red Sea Rift demonstrate the continuous formation of oceanic crust via volcanic processes in spreading centers.

Effects of glacial forcing on lithospheric motion and ridge spreading.
2025 · cited by 0
Research shows that lithospheric motion and spreading rates at mid-ocean ridges are significantly driven by external mechanisms such as glacial cycles and deglaciation rather than active lava-pushing alone.
