plate tectonics
The friction between the convective masses in the mantle and the crust overlaying it causes the crust to move.
thermal convection is the primary force that cause the sea floor to spread
Geothermal Drift.
Continental drift :)
Continental drift :)
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.
Your question is unclear. Who couldn't identify the force behind continental drift?
thermal convection
the Continental Drift Theory is the slow movement of the Earths continents. A.K.A the continents drift
Yes, they could not find a reason that would cause the movements of the continents. Now, scientists have discovered that the continents don't drift, but rather they are carried by tectonic plates.
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.
Wegner believed that the force causing continental drift was the movement of the continents through the Earth's crust, driven by the gravitational forces associated with the rotation of the Earth. This movement was theorized to be a result of the continents floating on the denser, underlying mantle layer.
