This will be about Sea floor spreading and what it does. Sea floor spreading is a procedure that happens at mid-ocean ridges where new oceanic crust is created. So when the magma comes up it separates the bottom of the sea floor and pushes it back down and around back to the core to be recreated as magma to be apart the cycle once again; when the cycle reoccurs the magma comes up and will be the sea floor again, completing the cycle. The sea floor spreading cycle creates the movement for the tectonic plates by creating more sea floor.

The mid Atlantic ridge like most of the other ridges has developed the consequence of the divergent motion from the North American plate, the Eurasian plate, the South American plate and the African plate. As the mantle rises the pressure around the mid Atlantic ridge is lowered which is called decompression, and the molten rocks start to melt partially. This makes ballistic volcanoes when a eruption occurs above the surface and characteristics basalts " pillow wolves " in underwater eruptions. After this happens, the plates move further away new ocean is formed and creates new ocean floor and the previous gets older, this process is called sea floor spreading and results symmetrical alignment of the rocks of the ocean floor which gets older.
