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. :]
Seafloor spreading forms new oceanic crust at mid-ocean ridges when tectonic plates move apart. As magma rises and solidifies, it creates new seafloor, pushing the older crust outward. This process contributes to the spreading of the seafloor and allows for the recycling of Earth's crust.
The process that forms new seafloor is called seafloor spreading. It occurs at mid-ocean ridges where new oceanic crust is created through volcanic activity. As magma rises and solidifies, it adds to the seafloor, pushing older crust away from the ridge and creating a continuous process of crust formation.
They proved that the seafloor was 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.

At a divergent boundary, land is gained. Ocean ridges are prominent at divergent plate boundaries. Ocean ridges are areas of seafloor spreading. Seafloor spreading occurs as upwelling magma rises to the surface. This upwelling magma hardens and forms new seafloor.
Seafloor spreading is a geological process where tectonic plates move away from each other, allowing magma from the mantle to rise and solidify, creating new oceanic crust. This process occurs at mid-ocean ridges and is a key component of plate tectonics theory.

This process is called seafloor spreading. It occurs at divergent plate boundaries where tectonic plates move apart. Magma rises up from the mantle through the cracks, solidifies upon contact with the cold seawater, and forms new oceanic crust.
The driving force for seafloor spreading is the movement of tectonic plates. As magma rises from the mantle to the surface at mid-ocean ridges, it creates new oceanic crust which pushes the existing plates apart, causing seafloor spreading. This process is part of the larger theory of plate tectonics.

True. When solid mantle rock rises during seafloor spreading, the decrease in pressure causes decompression melting, resulting in the production of magma. This magma can then rise to the surface and form new oceanic crust.

Yes, during seafloor spreading, when solid mantle rock rises due to plate tectonic forces, it experiences reduced pressure which leads to decompression melting. This process produces magma that eventually erupts onto the seafloor, creating new oceanic crust.
