Life Can Affect the Rotation Speed of the Earth

Washington, Dec 29.- Living organisms can influence the rotation speed of a planet by releasing gases such as oxygen into the atmosphere, revealed today a study by Columbia University in New York.

According to its author, the astrobiologist Caleb Scharf, currently, the Earth needs around 24 hours to complete a day, but maybe before it only took two to three hours.

He added that the gravitational pulls of the Sun and the Moon helped slow down the orb's rotation for billions of years at its current speed, an effect known as tidal braking.

Scharf pointed out in his study that terrestrial life could influence the speed of the planetary turn through various mechanisms.

'Organisms can influence atmospheric chemistry by emitting gases such as oxygen, which in turn affect the way atmospheres heat up and cool off and that could slow the rotation of the orb,' the scholar explained. (Prensa Latina)
