Which type of boundaries is seafloor created by?
Seafloor is created at divergent plate boundaries called the mid-ocean ridges.
What boundary creates seafloor spreading?
Divergent boundaries.
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 happens when divergent boundaries occur in the middle of an ocean?
A ridge with transverse faults is formed, where new oceanic crust (seafloor) is formed.
What forms when continental plates pull apart at divergent boundaries on land?
On land, this forms a rift valley. When the surface is submerged, it is called seafloor spreading.
Which type of boundaries is seafloor created by?
Seafloor is created at divergent plate boundaries called the mid-ocean ridges.
Where are most divergent boundaries found?
On the seafloor. Yes, the mid oceanic ridges are all divergent boundaries.
What boundary creates seafloor spreading?
Divergent boundaries.
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.

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.
In the process of sea floor spreading what happens when magma rises to the earths surface and solidifies?
Yes. Seafloor spreading is the term given to the creation of new seafloor at divergent boundaries. At a divergent boundary, two oceanic plates move apart, which obviously means that something must then surface to fill the void. This is where the magma rises from the Earth's interior and cools to become seafloor. On the other end, at convergent boundaries, the old seafloor is forced under the continental plates, where it is recycled back into the Earth's magma supply.

What is the midatlantic ridge?
The Mid-Atlanic Ridge is the divergent boundary that is responsible for seafloor spreading. Consisting mostly of divergent boundaries, with transform faults as well, this is the site where new oceanic crust is added, increasing the size of the ocean. This location is dotted with underwater volcanoes as igneous basaltic magma is added to fill in the gap left as the oceanic plates drift away.
How is seafloor spreading formed?
This happens at divergent boundaries where the plates move away from each other. Magma slips up here and forms new crust.
