Three lines of evidence are given below.

Explanation:

There is ample evidence that suggests the hypothesis of seafloor spreading along the deep oceanic ridges. Harry Hess back in 1960 is supposed to have given valuable evidence in the history of deep-sea exploration. His theory of evidence came after the pronounced theory of Alfred Wegener. One of them being

Magnetic Anomalies (paleomagnetism): These cover the entire ocean floor in terms of bands of hard and soft rock. The magnetic reversals that have been documented from studies of land. Positive anomalies in paleomagnetic theories suggest that the lava or magma which upon solidification of either side of the ridges took the direction of the earth's magnetic alignment and similarly with that of the negative anomalies.

Age of seafloor: The oldest known seafloor is a date about 200 million years. Indicating that older seafloor has been destroyed by a trench some years ago. Similarly, the younger oceanic crust can be found along the ridges as compared to older far apart.

Seismic studies. This proof comes from the earthquake produced along the rift valleys of mid-oceanic ridges and the cross-cutting feature that offset it. Because of the way the sea floor spreads the transform faults are found along with the boundaries of these ridges. Both for in the opposite direction of mid-oceanic ridges.
