Molten materials and magnetic stripes are the evidence of seafloor spreading.

When scientists studied patterns in the rocks of the ocean floor, they found more support for sea-floor spreading. In 1960, scientist dived to the ocean floor in Alvin. In a ridge's central valley, Alvin;s crew found strange rock shape pillows or like toothpaste squeezed from tube. Such rocks form only when molten materials hardens quickly after erupting under water. These rocks shows that molten materials has erupted again and again along mid ocean ridge.
