Convection currents within earth's mantle are responsible for both continental drift and sea floor spreading. The heat driving these currents comes largely from the decay of long lived isotopes trapped in earth's core and mantle.
Seafloor spreading is caused by two plates moving apart. This is caused by plate tectonics. Continental drift is also caused by plate tectonics. Therefore, we can conclude that continental drift is related to seafloor spreading. When the plates move, it carries the continents with it, and thus the continents drift away from each other.
Ocean currents have no effect whatsoever. Seafloor spreading is caused by convection currents in the rock of the earth's mantle.
its not happy
How seafloor spreading helps to explain the theory of continental drift is that wegener couldn't explain why and waht force caused the continents to move and so seafloor spreading helps to explain the theory of continental drift because it shows the force that made the continents move and that was te only thing that wagener needed to prove his theory of continental drift............thanks
The ages of the rocks become older the farther the way they are from the ridges. The closer they are the younger it is. This leaves evidence to the seafloor spreading theory.

They proved that the seafloor was spreading.
A diagram that shows how seafloor spreading works.
Seafloor spreading is triggered by a rift in a continental land mass.
Gravity in the oceanic crust is responsible for seafloor spreading.
Seafloor Spreading
Seafloor Spreading helped move the Continents to their current location.
When seafloor spreading occurs, it pushes the underground magma up though the new crust, creating a sort of volcano out of the new crust. Magma is a very important part in seafloor spreading. :]
