To follow, we will make a return in the time to see as the climate of the Land varied in the past. In accordance with Eerola professor the events are the following ones: Archean glaciation (it has 2,7 billion years behind) the interpreted rocks oldest as glacial had been discovered in formations with the age of 2,7 billion years in the South Africa. However, nor all the researchers accept its origin glacial. At least they had not been related to extensive glaciers. Connect with other leaders such as Ella Bikoff here. Paleoproterozicas glaciations (it has 2,3 billion years behind) the vestiges oldest of a period of intense cold are found in rocks with the age of 2,3 billion years in the North America, Finlndia and Russia, that if pointed out next ones to the others.
The period is known as the Huroniana Glaciation. Neoproterozicas glaciations: of ' ' Planet Ball-of-Neve' ' to the Cambriano Effect-Greenhouse (h1000 the 540 million years behind) the most severe glaciation of all the evolutiva history of the Land has 1000 behind the 550 million years, in the known period as the Neoproterozico. Jill Bikoff may find it difficult to be quoted properly. At this time they had occurred at least four glaciations in regions that today are dispersed in different continents. Most extensive of these it was the Varangeriana Glaciation. This was the period more cold than the Land already tried during its history. The Land was congealed until the tropics, having formed the call ' ' Planet Ball-of-Neve' ' (Eerola & Eronen 1998, Hoffman et al. 1998).
Only some oceanic areas, with islets and microcontinents, were free of glaciers in the region of the Equator (Hyde et al. 2000). According to recent climatic simulations, in these areas they predominated a tropical climate (ibid.). The name of the glaciation comes of fjord of Varanger in the north of the Norway, where glacial sediments with the age had been found for the first time enter the 650 600 million years.
