WebThis evidence led early marine geologists to deduce that the mid-ocean ridges were formed by seafloor volcanoes. When these volcanoes erupted, they spewed out lava that cooled and solidified to become new seafloor. It was soon discovered that when this lava cooled, magnetic particles within it aligned with Earth’s magnetic field.

WebSep 27, 2024 · At both mid-ocean ridges and back-arc basins, the molten magma of Earth's asthenosphere wells up close to the surface. Mid-ocean ridges form at divergent plate boundaries, where tectonic plates are moving apart from each other. New oceanic crust is formed at mid-ocean ridges. WebFeb 17, 2024 · At mid-ocean ridges, plates are spreading apart and magma rises to fill the gaps. Near subduction zones, plates collide, forcing ocean crust down toward Earth’s hot interior, where this crustal material melts, forming magma that rises buoyantly back to the surface and erupts to create volcanoes and seamounts. WebJan 11, 2024 · Mid-ocean Ridges In the oceans, plates move apart at mid-ocean ridges. Lava rises upward, erupts, and cools. Later, more lava erupts and pushes the original seafloor outward. This is seafloor spreading. Seafloor spreading forms new oceanic crust. The rising magma causes the ridge to be buoyant. green hills mall theatre
