We Shrinking Planet



Our planet is shrinking, said the Russian geologist. Since it was first built 585 kilometers of the earth has been reduced.

Vyacheslav Orlenok, professor of geology at the Kant Russian State University, Kaliningrad, comparing the ancient with the relief structure that existed at the moment.

He said 4.5 billion years ago, when the earth's surface just beginning to solidify a larger size. Estimated radius of about 6956 km and is currently 585 km has decreased.

For thousands of years the surface decreased by about 128 million square kilometers. Count is obtained by comparing the total area of all continents now reached 149 million square kilometers. "Depreciation is a major factor in processes such as tectonic movements in the continental platform," said Orlenok.

The reduced size caused by gravity and the mass loss caused by solar radiation, blowing away the hydrogen atoms of the earth's atmosphere, scientists explained. He has studied the formation of oceanic crust of the earth and for more than 30 years
