This story appears in the August 2010 issue of National Geographic magazine. Thirty-seven million years ago, in the waters of the prehistoric Tethys Ocean, a sinuous, 50-foot-long beast with ...

Spanning 1.2 million square miles (3.1 million square kilometers) and located southwest of India, the gravity hole’s formation is tied to the ancient Tethys Ocean and complex mantle processes.

Areas near the coast were pummeled by seasonal monsoons, but ocean-circulation patterns kept the isolated and vast interior warm and dry. Even the Poles were ice-free. The Tethys Ocean filled the ...

India charged across the equator at rates of up to 15 cm/year, in the process closing an ocean named Tethys that had separated fragments of Pangea. This ocean is entirely gone today, although the ...

The Indian Ocean "gravity hole" is Earth's deepest geoid low. Its weak gravitational pull makes sea levels here 348 feet lower than average, creating a 1.2-million-square-mile anomaly southwest of ...

The team has discovered high-pressure and ultrahigh-pressure metamorphic rocks, and unearthed crucial clues to advance understanding of the ancient Tethys Ocean, the supercontinents of Gondwana 2 ...

Earth's deepest gravitational anomaly, known as the "gravity hole," lies 1,200 km southwest of India in the Indian Ocean. Spanning ... fragments from Tethys disrupted high-density material in ...
