The presence of mid-ocean ridges provides evidence of continental drift because these ridges are long underwater mountain ranges that run along the ocean floors. The theory of plate tectonics explains that these ridges are formed as tectonic plates move apart from each other, allowing magma from the mantle to rise and solidify, creating new oceanic crust. This process supports the idea of continental drift, as the movement of tectonic plates causing the formation of mid-ocean ridges suggests that the continents were once connected and have since moved apart.
