Human consciousness is required this time, the earth no longer can survive long. And there when it all will end. Knowledge will be given to you about the movement of the earth. Or rather the movement north and south poles of the earth
Each of approximately 200 thousand years or so, the two poles of the planet earth, north and south of each shift. Generally, the two poles shift takes thousands of years.
Scott Bogue, a geologist from Occidental College and Jonathan Glen, researchers from the U.S. Geological Survey (USGS) to observe the lava in the area of Nevada which has 15 million years old.
The results, from research, they discovered that the planet's poles have shifted several times faster than normal speed. At least once.
"When lava cools, it keeps a record of the Earth's magnetic field," Bogue said, as quoted from Discovermagazine, December 23, 2010. "After observing the cooling of lava during the second year in a row, it is known that the lava in the region shifted 53 degrees from south to north with a speed of 1 degree every week," he said.
Initially, they thought there was an error in their research. However, more detailed testing to confirm the shift pattern. Other evidence of polar shift recorded by lava flows in Oregon, which has been investigated in the last 1985 years.

Geological record of Earth's magnetic field also generally indicates that the north-south magnetic field shifted once about every 200 thousand years. The shift occurs slowly and requires a 4 thousand years to complete.
Although scientists have not determined what makes the shifting of the poles, hot liquid metal that can conduct electricity that flows in the bowels of the earth is estimated to be the cause. Moreover, these substances are also likely to cause the magnetic field at Earth's poles.
The findings are expected to trigger a new wave of debate. A number of geologists argue that the current magnetic field is also currently undergoing a shift.
As reported in Science News, planet Earth's magnetic field weakened over the last century. Nevertheless, the shift of the magnetic field will not affect too many people's lives.
