Seafloor spreading is the process by which new oceanic crust is formed at mid-ocean ridges as tectonic plates diverge and magma rises to the surface. This results in the creation of new ocean floor, leading to the expansion of ocean basins. As seafloor spreading occurs, features such as mid-ocean ridges, rift valleys, and volcanic islands can also form as a consequence. Additionally, this process contributes to the cycle of plate tectonics, influencing geological activity and the distribution of continents.

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.
New oceanic lithosphere forms as a result of?
New oceanic lithosphere forms as a result of seafloor spreading at mid-ocean ridges. Magma rises from the mantle, solidifies at the mid-ocean ridge, and creates new oceanic crust. This process leads to the continuous expansion of the ocean floor.
What did the magnetic strips prove in seafloor spreading?
They proved that the seafloor was spreading.
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.
How to Diagram the process of seafloor spreading?

Is seafloor spreading a process that forms a new oceanic crusts?
Yes, it is.

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 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.
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.
