When magma rises through sea floor rifts, it cools and solidifies into new oceanic crust as part of the process known as seafloor spreading. This creates new crust at the boundaries of tectonic plates, contributing to the continual movement and renewal of the Earth's outer shell.
The crack in the ocean floor where magma rises is called a mid-ocean ridge. At these underwater mountain ranges, tectonic plates separate and magma rises to fill the gap, creating new oceanic crust. This process is known as seafloor spreading.
The magma forms sills and magma chambers.
A volcanic mountain forms from the magma that is created by sea-floor spreading. This magma rises to the surface and solidifies, creating a volcanic mountain range along the mid-ocean ridge where sea-floor spreading occurs.
this usually happens when the sea floor spreads open.
Creation of new crust through up swelling and out rising of magma to cover areas of sea floor spreading or lithospheric seperation.
The magma spills over the ridge and pushes the old sea floor away toward a subduction zone where the old sea floor melts.
