Earth has subsided before 2 billion years and no one knows why

A new study gave evidence that our planet has experienced geological break in the pre-2.3 and 2.3 billion years and then did not occur near any processes of formation of rocks. This dormant phase of the Earth signals a significant change in the dynamics of tectonics and opens questions about how truly have formed the continents. Scientists expect the discovery could give better details on where to find deposits geologically important mineral resources.

The era of the pause is known as Paleoproterozoyska era and it is considered by geologists as a very exciting period in the development of the planet. Everything was very different then. The days were with 4:00 shorter. The atmosphere has not had a lot of oxygen. They started the first global glaciations. And he formed the first supercontinent on the planet - a large land mass called Colombia or Noonan. Scientists want to understand as well how it looked then-land compared with today. A geological break has lasted 250 million years, which is a significant period of time even geological scale. Volcanoes have gradually subsided considerably and the movement of tectonic plates were minimal. It is possible that the reason for this was the significant cooling of the Earth's coreBut to verify this hypothesis is still much work.
