∙ 13y ago1. Paleomagnetism. 2.(Thickness of the beds) Samples of the deep ocean floor show that basaltic oceanic crust and overlying sediment become progressively younger as the mid-ocean ridge is approached, and the sediment cover is thinner near the ridge. 2. (Age of the sea-floor) The rock making up the ocean floor is considerably younger than the continents, with no samples found over 200 million years old, as contrasted with maximum ages of over 3 billion years for the continental rocks. This confirms that older ocean crust has been reabsorbed in ocean trench systems. 3. (Geologic Activities) Study of the fracture zones that offset the sections of the ridge.

Not really but sea floor sediments thickness increase with increased distance from spreading centers which is good evidence. Other evidence such as magnetic reversals, temperature, dating methods provide the best evidence of seafloor spreading

The ages of the rocks become older the farther the way they are from the ridges. The closer they are the younger it is. This leaves evidence to the seafloor spreading theory.

three are : eruptions of molten material magnetic stripes in the rock of the ocean floor and the ages of the rocks themselves :)
