seafloor spreading
Rocks near continents(on the margins of oceanic basins) are generally older and rocks near a center of sea floor spreading are younger
They proved that the seafloor was spreading.

A diagram that shows how seafloor spreading works.
seafloor spreading
Rocks in the seafloor are moving one place to another
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.
Harry Hess hypothesized that the sea floor was spreading. He explained it through the phenomena of the youngest rocks that are found only at the mid-ocean ridges. These rocks then, get progressively older when moving away from the 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.
The youngest seafloor rocks are found in the rift valleys of the mid ocean ridges. At the mid-oceanic ridges there is tectonic movement bringing new magma to the surface.
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.
The seafloor rocks vary in different places. Rock samples near ocean ridges are younger than rocks at deep sea trenches

at the mid-ocean ridge, molten material rises up from the mantel and spreads out, pushing the older rocks to both sides of the ridge.
