WebMay 6, 2024 · Plates move apart at mid-ocean ridges where new seafloor forms. Between the two plates is a rift valley. Lava flows at the surface cool rapidly to become basalt, but deeper in the crust, magma cools more slowly to form gabbro. So the entire ridge system is made up of igneous rock that is either extrusive or intrusive. WebTectonic Plates of the Earth By Earthquake Science Center. Original Thumbnail Medium.
