What occurs at plate boundaries that are associated with seafloor spreading?

When seafloor spreading happens, a rift forms at the bottom of a ocean and separates to form new rock. This is an example of a divergent plate boundary

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.
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. :]
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.
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.
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 occurs at divergent boundaries and creates new seafloor?
At divergent plate boundaries the spreading of the tectonic plates results in the reduced pressure of the underlying magma. As the spreading continues, lava fills in the area of spreading and cools, becoming the newest addition to the seafloor. This process occurs at a steady rate ranging from a few centimeters to several centimeters of new sea floor each year. However, at a different location opposite the newly formed seafloor are convergent plate boundaries where land and seafloor is destroyed to make room for new seafloor.
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.

Does sea floor spreading occur at a convergent boundary?
No. Seafloor spreading occurs at a divergent boundary.
How do you explain the process of the seafloor spreading?
The seafloor spreading definition is the geologic process that occurs at the boundary between 2 plates where molten material within the earth pushes its way up, causing the plates to move away from each other. At these divergent boundaries molten material cools and hardens, creating new oceanic crust or seafloor

Where is place where seafloor spreading occurs?
One example would be...the mid-atlantic ridge.
