Question

How does seafloor spreading cause continents to drift?

Answer 1

Hint:Harry jessy discovered the seafloor spreading. Seafloor spreading helps to give an explanation for the continental float in the form of plate tectonics. When the oceanic plates diverge, the tensional stress reasons, fractures to occur in the lithosphere.

Complete answer:
Seafloor spreading is the process that happens at the mid-ocean ridges, where the new oceanic crust is shaped through the volcanic endeavor and then progressively strikes away from the ridge of the ocean.

Seafloor spreading creates a new oceanic crust at a mid-ocean ridge. When this new cloth reaches the give up of the plate and comes into contact with some other plate, whether or not continental or not, a convergent or a seriously changed boundary will occur.

Depending upon the boundary type, the two plates will move (one subducted under the different or the two crash alongside each other), but the seafloor spreading is not surely the reason for the continental plate to drift in either of the cases.

The new material is created due to the seafloor ,spreading at the mid ocean ridge. On the one side, the oceanic crust is subducted under the continental crust of the earth. On the other side, the two plates collide in a transform boundary, which is a horizontal kind of movement. The latter is the closest we truly come to continents drifting.

Note:Seafloor spreading takes place at the divergent plate boundaries. As the tectonic plates slowly passes away from each other, warmth from the mantle's convection currents makes the crust greater plastic and also it makes the less dense populated.
