How do you calculate the rate of seafloor spreading?
rate of spreading for stripe = width of stripe / time duration If a magnetic strips is 60 km wide and formed over 2 million years, then the rate at which spreading formed the was 30 km/m.y. The rate is equivalent to 3 cm/year. Spreading added an equal width of oceanic crust to a plate on the other side of the mid-ocean ridge, so the total rate of spreading across the ridge was 60 km/m.y. (6 cm/year), a typical rate of seafloor spreading.
What is the modern seafloor spreading rate range?
Typical rates of spreading average around 5 centimeter (2 inches) per year.
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
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.
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.
What is the modern seafloor spreading rate range?
Typical rates of spreading average around 5 centimeter (2 inches) per year.
Why are the magnetic strips in the pacific ocean wider than the ones in the Atlantic ocean?
The Pacific seafloor formed at a faster spreading rate than the Atlantic seafloor.
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 process forms new seafloor?
Seafloor spreading at midoceanic ridges.
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. :]
