the ages of the rocks become increasingly older in samples obtained farther from the ridge and the younger had just come out the ridge.
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.

Harry Hess came up with the theory of seafloor spreading . Alfred Wegener came up with the idea of continental drift NOT sea-floor spreading.

An isochron is a line on a map that connects points that have the same age. An isochron map of the ocean floor supports the theory of seafloor spreading because it shows the older rock near the deep sea trenches and the younger rocks near ocean ridges.
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.

seafloor spreading, age of the sea floor and ocean trenches.
The theory of seafloor spreading was proposed by Harry Hess, a geologist and Navy officer, in the early 1960s. He proposed that new oceanic crust is formed at mid-ocean ridges and then spreads outward. This theory helped to explain the mechanism behind continental drift and plate tectonics.
New material is added to the sea floor when sea floor spreading occurs. When the iron cools it is magnetized by the magnetic field of the earth.

The features of the ocean floor, such as mid-ocean ridges, deep-sea trenches, and underwater volcanoes, provide evidence for the theory of plate tectonics. These features are formed by processes like seafloor spreading, subduction, and volcanic activity, which are central to the movement of Earth's tectonic plates. Additionally, the magnetic striping pattern on the ocean floor supports the idea of seafloor spreading and plate movement over time.
