Best Answer

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.

How does seafloor spreading explain continental drift?

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.


What kinds of ocean currents might cause seafloor spreading?

Ocean currents have no effect whatsoever. Seafloor spreading is caused by convection currents in the rock of the earth's mantle.

What does magma have to do with seafloor spreading?

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. :]
