What evidence do scientists have that verify that indeed the earths plates are spreading at the mid ocean ridges?

Scientists have gathered evidence for the spreading of Earth's plates at mid-ocean ridges through various methods. One key piece of evidence is the age of oceanic crust, which increases with distance from the ridge, indicating new crust is formed at the ridge and pushed outward. Additionally, magnetic striping on the ocean floor reveals symmetrical patterns of magnetic reversals, supporting the idea of seafloor spreading. Seismological data also show earthquakes occurring along plate boundaries, further confirming the movement of tectonic plates.
