Research reveals Earth’s core affects length of day

The Extinction Protocol

July 15, 2013GEOLOGYResearch at the University of Liverpool has found that variations in the length of day over periods of between one and 10 years are caused by processes in the Earth’s core. The Earth rotates once per day, but the length of this day varies. A year, 300 million years ago, lasted about 450 days and a day would last about 21 hours. As a result of the slowing down of the Earth’s rotation the length of day has increased. The rotation of the earth on its axis, however, is affected by a number of other factors – for example, the force of the wind against mountain ranges changes the length of the day by plus or minus a millisecond over a period of a year. Professor Richard Holme, from the School of Environmental Sciences, studied the variations and fluctuations in the length of day…
