Seafloor spreading occurs when two tectonic plates move further away from each at mid-ocean ridges. In these ridges new crust is formed through volcanic activity and thus expanding the seafloor.

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.
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.

Seafloor spreading begins when?
Seafloor spreading is triggered by a rift in a continental land mass.

What does seafloor spreading have to do with the theory of continental drift?
Seafloor Spreading helped move the Continents to their current location.
When solid mantle rock rises during seafloor spreading magma is produced as a result of decompression melting?
Yes.
What phenomenon occurs as a result of seafloor spreading?
In 1960, seafloor spreading was hypothesized by Harry Hess of Princeton University. Seafloor spreading occurs at divergent boundaries and it is said to be the mechanism that operates along the oceanic ridge system to generate new seafloor. Thus, the result of seafloor spreading is the creation of new sea floor through the uplift of magma: magma raises from asthenosphere, new oceanic lithosphere moves from ridge, and it thickens, cools (becomes denser), and subsides.
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.
What seafloor is the process by which new crust is created when seafloor moves apart and magma rises?
Seafloor Spreading
