What is sea floor spreading?
Sea floor spreading is part of plate tectonics, this forms new crust from cooled lava. This occurs near mid-ocean ridges and large mountain ridges. An example of this The Mid-Atlantic Ridge.

Harry Hess and his contribution.
Harry Hess started mapping out the ocean floor when he was in the Navy. He discovered many flat-top mountains and after the war he decided to research more about it. He hypothesized that the sea floor was spreading. He also discovered guyots.
Evidence for this theory included molten material and others. Scientist uses material found at the bottom of the ocean. They also drilled and found molten material describing how it moved. They also discovered through magnetism in the samples, that Earth's magnetic poles would reverse themselves.
