Geothermal Drift.
thermal convection
The primary force driving seafloor spreading and continental drift is mantle convection. Heat from Earth's core causes the mantle to circulate, creating convection currents that move tectonic plates, leading to the spreading of the seafloor and movement of continents.
The primary force that causes the seafloor to spread and continents to drift is plate tectonics. This process is driven by the movement of molten rock in the Earth's mantle, which generates forces that push apart tectonic plates, leading to seafloor spreading and continental drift.
In the middle of the ocean is a rift where the ocean floor squeezes out lava and pushes the ocean plates apart.

Radiologyinfotation
The primary force behind seafloor spreading and continental drift is convection currents in the Earth's mantle. These currents move the tectonic plates above them, causing them to either spread apart or collide. The spreading of seafloor and the shifting of continents are part of the larger process of plate tectonics.

Convection currents
The primary force that causes the sea floor to spread and continents to drift is called "plate tectonics." This geological process involves the movement of the Earth's lithosphere (made up of tectonic plates) on the semi-fluid asthenosphere below, driven by convection currents in the mantle.
