floor is sea floor spreading. 27 Evidence for Sea Floor Spreading. In the 1960s scientists found evidence that new material is erupting along the mid-ocean ridge. The presence of pillow shaped rocks has showed that molten material has erupted again and again. 28 Pillow Lava rocks. 29 Evidence for Sea-Floor Spreading 31  32 . In the 1968, scientists aboard the Glomar Challenger gathered information about the Sea floor. They found rocks no older than 180 million years. 33 Evidence of Sea-Floor Spreading. Evidence from drilling into the sea floor shows evidence of the ages of rocks.
