The Ninetyeast Ridge is the Earth 's longest straight underwater mountain chain.

It stretches 5,000 km along the Indian Ocean's 90-degree east longitude and nearly matches the length of North America's Rocky Mountains .

High-precision dating of minerals extracted from the ridge shows it formed between 83 and 43 million years ago as a massive volcanic chain, with its oldest sections in the north, near India .

Discovery revises the estimated age and origin of the ridge.
