Melting of ice in Antarctica and Greenland have increased the volume of the oceans and the water continues to exceed the equatorial region, thereby increasing the thickness of the widest part of our planet, according to scientists.
Earth initially 'look slimmer' to the ice age, which ended about 20,000 years ago.
During this geological period, the reduced surface temperature and the atmosphere in the long run, resulting in a heavy layer of ice so large that shape the Earth's crust and mantle changed, causing a bulge in pertengahannya.
Earth is not completely round-the plain of the Arctic a few miles closer to the core of this planet than the plains on the Equator.
This effect is believed to rebound in the Ice Age that resulted in our planet becomes more perfect.
'Bulge' on the Equator has shrunk to one millimeter per year, according to National Geographic.
But be monitored through satellite measurements Gravity Recovery and Climate Experiment (GRACE), found that these effects have been berbalikkan.
"There are other things that will offset the (shrinking of the thickness of the Earth)," said John Wahr, an expert in geophysics at the University of Colorado.
Rate of ice melting in the Arctic and the South-which totaled 382 billion tons per year will counteract and neutralize the effect of 'slimming'. (Erabaru / DM / husband)
