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.
Yes, when the seafloor spreads apart, hot magma rises and creates new crust at mid-ocean ridges. This process can heat up seawater in the cracks, leading to hydrothermal vents where hot, mineral-rich water is ejected into the ocean.
Magma is more buoyant than lithospheric rock, and as such it will push toward the surface. On the continents, magma in intrusions can follow weaknesses in the crustal rock to reach the surface, or in some cases, simply melt its way through from the heat delivered by the intrusion. At divergent plate boundaries, where the lithospheric plates are pulling apart, hot rock from the mantle rises and melts from decompression melting, filling the space left from the parting plates. At so-called hotspots, such as the Hawaiian volcanic mountain chain, magma plumes are thought to rise up from the mantle-core boundary and burn through the moving lithospheric plates, creating first submarine volcanoes, then islands.
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.
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.
The system of cracks that form where the seafloor is spreading apart is called a mid-ocean ridge. These cracks are also known as rift zones and are where magma rises to create new oceanic crust.
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. :]

You will need to defeat the Team Aqua or Magma grunts in the Seafloor Cavern and make your way though their ranks to the leader of Team Aqua/Magma.
Seafloor Spreading
Magma often moves upward through the Earth's crust along cracks and fractures in the rock, known as magma conduits. These conduits can be created by tectonic activity, such as the movement of tectonic plates, which can provide pathways for magma to reach the surface and form volcanic eruptions.
