The Earth Once Turned White from Blue like A Snowball

It's hard to envision now, yet at specific times in the history of the Earth, the entire planet was covered in ice. This Earth froze and was given the nickname of snowball Earth. The situation was so serious, that the Earth's whole surface, from one pole to the other, including the seas, totally solidified. Melissa Hage, an ecological researcher and collaborator educator at Oxford College of Emory University in Georgia confirmed in a statement. In 1840, a Swiss natural scientist, Louis Agassiz was one of the first to recognize and give proof that Earth had experienced ice ages, as indicated by the University Of California Museum Of Paleontology. An American geologist, Joseph Kirschvink, later authored the term "snowball Earth," in a 1992 report. Kirschvink's work depended on proof given by Agassiz and others. Researchers think that the surface of the earth frozen by about three to four severe ice ages, happened between 750 million and 580 million years prior, likely in light of the fact that the land masses of the earth were altogether situated at or close to the equator, which brought about expanded weathering. This happens when wind and precipitation cause the rocks and minerals to break down on the planet's surface. The procedure prompts diminished carbon dioxide levels in the climate, which enables more warmth to disseminate from the surface as well as in space, causing the planet to cool down. Hage further explained that Hage further explained that expanded weathering of the mainland prompted abatement in environmental carbon dioxide and resulted in worldwide cooling. When the polar seas started to freeze, expanded sunlight was reflected off the white surfaces and cooling was intensified.
