because if the sea-floor is moving it will probably will move a chunk of land that could be part of a continent
the land at the bottom of the ocean is being spread across, and is taking space up. the continents are on tectonic plates, and need to go some where and move away.
What else can I help you with?
How sea-floor spreading provides a way for continents to move Explain?
Sea-floor spreading is the process where new oceanic crust is formed at mid-ocean ridges, pushing the existing crust apart. As the crust spreads, it carries the continents on tectonic plates with it, causing the continents to move. This movement is called plate tectonics, and it is responsible for the shifting of continents over geological time scales.
How does sea floor spreading provides an explanation for how continents move over earth's surface?
Sea floor spreading provides a way for the continents to move over Earth's surface. Continents are carried by the widening sea floor. The molten rock from a rift cools, hardens, and then moves away in the opposite directions on both sides of the ridges. hope this helps :)

How sea floor spreading provides a mechanism by which continents move?
Sea floor spreading occurs at mid-ocean ridges where tectonic plates move apart, allowing magma to rise to the surface, solidify, and form new oceanic crust. As new crust is created, it pushes the existing crust away from the ridge, effectively moving the continents on the plates they sit. This process is part of the theory of plate tectonics, which explains how continents drift and change positions over time.
How does sea floor spreading make the continents move?
Under the oceanic crust is the layer of the earth called the mantle. This layer is moving rock that is very, very hot! As the hot material in the mantle pushes up through the crust in the sea floor, it cools and becomes new crust as it pushes out (spreads) the sea floor. This movement in the plates causes other plates (continental and oceanic) to move as well. This is how sea floor spreading causes continents to move.
What are the steps in the sea floor spreading?
In sea-floor spreading,the sea floor spreads apart along both sides of the mid-ocean ridge as a new crust is added.As a result,the ocean floors move like conveyor belts,carrying the continents along with them.

What does sea-floor spreading have to do with the continental drift theory?
If you move the continents appart (or togther), then you need to create (or destroy) seal floor to do this.Thus there must be structures on the sea floor that relate to the process of continental drift/movement (and there are).
Why is sea-floor spread important yo the idea of moving continents?
Seafloor spreading is important because it provides evidence for the theory of plate tectonics, which explains how and why continents move. As new crust forms at mid-ocean ridges and older crust is pushed away, it helps drive the movement of the Earth's plates and contributes to the shifting of continents over time.
Why is the Atlantic Ocean is spreading?
The oceanic crust of the Atlantic Ocean floor is attached to the continental crust of the continents around the ocean. So as the Atlantic's Ocean floor spreads, the continents along its edges also move. Over time, the whole ocean gets wider.
