When examining rocks from both sides of the Mid-Atlantic Ridge, scientists found evidence for the phenomenon of seafloor spreading. This process involves the creation of new oceanic crust as magma rises from the mantle and solidifies at the ridge, causing the plates on either side to move apart. The age and magnetic orientation of the rocks increase with distance from the ridge, providing clear evidence of this continuous geological activity. This discovery has been fundamental in supporting the theory of plate tectonics.
