“Tharp’s work certainly provided evidence and weight to the theory of plate tectonics, but her work is really about seafloor ...

Magnetic bands provide evidence of sea-floor spreading 1963. In 1963, Fred Vine, Drummond Matthews, and others found that the crust surrounding the midocean ridges showed alternating bands -- each ...

Previously unseen features in the map include newly exposed continental connections across South America and Africa, and new evidence for seafloor spreading ridges at the Gulf of Mexico that were ...

The map has also revealed for the first time newly exposed continental connections across South America and Africa, and new evidence for seafloor spreading ridges at the Gulf of Mexico that were ...

That pattern became one of the most powerful lines of evidence for the hypothesis of seafloor spreading, the idea that as Earth’s crust pulls apart at the mid-ocean ridges, magma wells up to ...

Identification of the oldest preserved pieces of Earth's crust in southern Greenland has provided evidence of active plate tectonics as early as 3.8 billion years ago, according to a report by an ...
