Other than abundant matching fossils and sedimentary rock on opposite sides of the Atlantic Ocean and the apparent puzzle piece appearance of the continents on either side of the Atlantic, there is the presence of the mid-oceanic ridges, areas where new oceanic crust is created. The magnetic orientation of the basaltic oceanic crust as it forms is the mirror image of the magnetic orientation of the basaltic oceanic crust on the other side of the ridge, indicating that the seafloor is spreading in both directions away from ridge. Additionally, the dating of rock on the ocean floor has shown that oceanic crust and overlying sediment become progressively younger as the mid-ocean ridge is approached.
And finally, accurate measurements have been made by global positioning devices which verify that seafloor spreading is occurring.
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.
Ocean-floor rocks near mid-ocean ridges show a symmetrical pattern of magnetized stripes parallel to the ridge axis. These stripes result from periodic reversals in Earth's magnetic field and provide evidence of seafloor spreading. Sediments on the ocean floor also show younger ages near the ridges, supporting the idea of seafloor spreading.
Yes, there is evidence supporting seafloor spreading, including magnetic striping patterns on the ocean floor, the age progression of seafloor away from mid-ocean ridges, and the presence of hydrothermal vents along mid-ocean ridges that release magma from the Earth's mantle.
Paleomagnetic stripes on either side of mid-ocean ridges demonstrate the symmetric pattern of magnetic reversals found in oceanic crust, supporting the idea of seafloor spreading. Age dating of oceanic crust samples reveals that the further away from mid-ocean ridges, the older the crust gets, providing direct evidence for the continuous creation of new seafloor at spreading centers.
Lawrence W. Morley, Frederick John Vine, and Drummond Hoyle Matthews were the first to tie magnetic stripe anomalies to seafloor spreading. The magnetic anomalies was the first evidence that supported the theory of seafloor spreading.
Animal fossils have been found in many places in the ocean.

The Mid Atlantic Ridge
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.
Magnetic alignment of rocks, in alternating strips that run parallel to ridges, indicates reversals in Earth's magnetic field and provides further evidence of seafloor spreading.
people here are stupid , really the answer is not hi
dumb question. don't want to write it all

Convergence supports the theory of seafloor spreading. Samples of the deep ocean floor are evidence of seafloor spreading because the basaltic oceanic crust and overlapping sediment become younger as the mid-ocean ridge is approached. Also, the rock that makes up the floor of the ocean is younger than the continents.
