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. :]

At a divergent boundary land is gained or lost?

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 is the process by which new crust is created when the seafloor moves apart and magma rises up?

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.


What does seafloor spreading form?

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.


What is the process by which new crust is created when the seafloor moves apart and magma rises up?

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.


What is the driving force for seafloor spreading?

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.


Process that forms new seafloor?

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.


Is the following sentence true or false when solid mantle rock rises during seafloor spreading magma is produced as a result of decompression melting?

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.


What did the magnetic strips prove in seafloor spreading?

They proved that the seafloor was spreading.


When solid mantle rock rises during seafloor spreading magma is produced as a result of decompression melting?

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.
