Seafloor spreading is the extension of oceanic lithosphere that occurs where two oceanic plates are moving apart. While the explanation for its causes remain somewhat of a mystery, it goes something like this: oceanic plates at the mid-ocean ridges are either being pushed or pulled apart, probably a combination of both. Rock from the mantle rises and undergoes decompression melting, filling the void left by the separating plates. The lava then turns into the rock basalt and becomes an addition to the ocean floor. The ocean floor grows roughly equally on either side of the ridge. (if you're doing a project on seafloor spreading, i suggest you to put this in your own words. therefor, your teacher always check the internet to see if you're copying. I once got in trouble for that) ;)
What else can I help you with?
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.
Seafloor spreading begins when?
Seafloor spreading is triggered by a rift in a continental land mass.
Which observation was not instrumenntal in formulating the hypothesis of seafloor spreading?
The observation of the alternating magnetic stripes on the seafloor was instrumental in formulating the hypothesis of 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 seafloor is the process by which new crust is created when seafloor moves apart and magma rises?
Seafloor Spreading
What is the Site of the seafloor spreading?
how am i suposed to know
Does seafloor spreading hold the plates in place?
No, seafloor spreading does not hold the plates in place. Seafloor spreading is a process that occurs at mid-ocean ridges where new oceanic crust is formed and spreads apart. It is driven by the movement of tectonic plates, which are actually responsible for holding the seafloor in place.
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. :]
Description of seafloor spreading?
Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. Seafloor spreading helps explain continental drift in the theory of plate tectonics.
Why can't someone feel the seafloor spreading?
We can't feel seafloor spreading because the ocean is super deep that the continents will not shake or burst in somewhat actions.
