The positioning of continents, a previously unrecognized element, contributes to the oxygenation of Earth's waters. Moving continents may ultimately have the reverse result, killing most deep-sea animals.
A previously overlooked factor the position of continents helps fill Earth’s oceans with life-supporting oxygen. Continental movement could ultimately have the opposite effect, killing most deep ocean creatures.
Researchers from University of California, Riverside have warned that movement of Earth s continents could wipe out marine life in the deepest parts of the oceans by starving them of oxygen.
Rock samples from Quebec s Anticosti Island are offering new clues about Earth s first major mass extinction event 445 million years ago, suggesting that it may have been caused by a cooling climate.
