Describe how the age of seafloor rocks are evidence for Seafloor Spreading. Where are the youngest rock found? The oldest?

Rocks of normal and reversed polarity are found in stripes symmetrically about the mid-ocean ridge axis. The age of seafloor rocks increases from the ridge crest to rocks the farthest from the ridges. Still, the rocks of the ocean basins are much younger than most of the rocks of the continents. Accordingly, the oldest rocks in a sequence are at the bottom and the youngest rocks are at the top.The scientists used geologic dating techniques on seafloor rocks. They found that the youngest rocks on the seafloor were at the mid-ocean ridges. The rocks get older with distance from the ridge crest. The scientists were surprised to find that the oldest seafloor is less than 180 million years old.
