Does sea floor spreading occur at a convergent boundary?
No. Seafloor spreading occurs at a divergent boundary.
Who discovered Seafloor Spreading?
Henry H. hess
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 are two pieces of evidence for sea-floor spreading?
Magnetic stripes and absolute ages of seafloor basalt.
How is new rock added to the ocean floor?
usually from lava sinking to ocean floor and cooling.
What is this is the process of creating new oceanic crust?
Sea floor spreading
What is the process in which new sea floor forms as older sea floor is pulled apart?

How do the ages of the rocks on the ocean floor support the theory of seafloor spreading?
The ages of the rocks become older the farther the way they are from the ridges. The closer they are the younger it is. This leaves evidence to the seafloor spreading theory.

What evidence in rock supports the theory of seafloor spreading?
Convergence supports the theory of seafloor spreading. Samples of the deep ocean floor are evidence of seafloor spreading because the basaltic oceanic crust and overlapping sediment become younger as the mid-ocean ridge is approached. Also, the rock that makes up the floor of the ocean is younger than the continents.

What is ocean-floor 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.
What process in which new sea floor forms as older sea floor is pulled apart?
Seafloor spreading where new floor is formed. Subduction zone where older floor is pushed back into the mantle.
Does sea floor spreading occur at a convergent boundary?
No. Seafloor spreading occurs at a divergent boundary.
How does the ocean floor move?
It is called Seafloor Spreading, which comes under the Divergent Plate Movement.
