It forms at the edges of Divergent Tectonic Plates; as opposed to the Earthquakes that are found at the Convergent Plate Boundaries [where one Plate subsides beneath the other Plate].
Sea Floor Spreading
Just as new sea floor forms at mid-ocean ridges, new sea floor is forced back into the mantle at abduction zones. The oldest seafloor is at east and west the edges of the Atlantic Ocean, dating to the breakup of Pangaea.
As the sea floor spreads, the old ocean floor gets pushed out, which makes the plates move.
Sea floor spreading occurs at mid-ocean ridges
Under the oceanic crust is the layer of the earth called the mantle. This layer is moving rock that is very, very hot! As the hot material in the mantle pushes up through the crust in the sea floor, it cools and becomes new crust as it pushes out (spreads) the sea floor. This movement in the plates causes other plates (continental and oceanic) to move as well. This is how sea floor spreading causes continents to move.
Sea Floor Spreading!
Forms by lava from volcanoes on the sea floor
New crust
Forms by lava from volcanoes on the sea floor
new rocks form
sea floor spreading, boo. it's molten rockk from earth's coree. hope it helpped!! :)
Sea Floor Spreading
sea-floor spreading
the sea floor separates. magma comes up the crack forming new sea floor
Seafloor spreading where new floor is formed. Subduction zone where older floor is pushed back into the mantle.
