1.) The age of the rocks- the oldest ones are found further away from the original mid-atlantic ridge.
2.) Magnetic clues. The rocks with iron in them have shown that the Earth's magnetic field has reversed itself several times. It is imprinted in the rock.

What evidence in rocks supports the theory seafloor spreading?
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.

How do the ages of the rocks on the seafloor support the theory 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.
