I'm not that sure since I am doing a science assignment on seafloor spreading but, I think I've got a pretty good grasp on 5 steps
Magma pushes up through the Earth's mantle and breaks through the crust.
Magma flows outward in the ocean in all directions and hardens to form new ocean floor by the ridge.
New ocean floor pushes the old floor away from the mid-ocean ridge
The old floor then pushes the continents away from the ridge
Lastly, the old ocean floor is forced under the continental plate, and melts back into magma.

Is there evidence that seafloor-spreading?
its not happy
How do the ages of the rocks on the seafloor support the theory of seafloor spreading?
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.
How does the age of rocks in the seafloor provide evidence of seafloor spreading?
Rocks in the seafloor are moving one place to another
Seafloor is the process by which new crust is created when the seafloor moves apart and magma rises up?
seafloor spreading
Who discovered Seafloor Spreading?
Henry H. hess
What did the magnetic strips prove in seafloor spreading?
They proved that the seafloor was spreading.
How to Diagram the process of seafloor spreading?
A diagram that shows how seafloor spreading works.
Seafloor spreading begins when?
Seafloor spreading is triggered by a rift in a continental land mass.
Which force is responsible for seafloor spreading?
Gravity in the oceanic crust is responsible for seafloor spreading.
Process that forms new seafloor?
Seafloor Spreading
What does seafloor spreading have to do with the theory of continental drift?
Seafloor Spreading helped move the Continents to their current location.
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. :]
What process forms new seafloor?
Seafloor spreading at midoceanic ridges.
Is there evidence that seafloor-spreading?

What seafloor is the process by which new crust is created when seafloor moves apart and magma rises?
Seafloor Spreading
A typical rate of seafloor spreading in the Atlantic Ocean?
The typical rates of seafloor spreading is 5 centimeters per year. Seafloor spreading is a process that occurs at mid ocean ridges.
How do the ages of the rocks on the seafloor support the theory of seafloor spreading?
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.
