Dimensional Argument Against the Snowball Earth Hypothesis :: essays research papers
A most recent inquiry into climatic neuter during the water ice age and its possibility of reoccurring is the Snowball Earth guesswork advanced by Paul Hoffman of Harvard University. Snowball Earth Suggest that before the field glass age, continents ice free at the poles enhanced the reabsorption of carbon dioxide with erosion of silicate minerals, reducing the greenhouse doing making the earth colder until it reached a runaway point. This effect is Hoffman calls albedo, when the gentle wind becomes so cold it can neer warm up again. This is what occurred during the ice age, until volcano activity saturated the atmosphere with carbon dioxide to a point that it trapped radiation from the Sun and rewarmed the mood causing glacial thaw. Evidence of this event is cap carbonates that show congress dating at the ice age, found in abundance in several different world regions, at certain levels the cap carbonates would foreshadow if carbon dioxide was emitted into the atmosphere, by showing carbon levels that would demonstrate how very much photosynthesis was occurring. urge on rich rock deposits indicate that absents of oxcidation would mean the atmosphere contain no oxygen, with pop out oxygen their is no life, therefore other evidence of total extinction. So experts dispute the oceans were encased beneath a kilometer thick pall of ice sheet, or that all life became extinct. The evidence of the Snowball effect is challenged that levels of carbon had not reached those required to satisfy the model and that alternative models atomic number 18 possible to explain the arrival and conclusion of the ice age. Iron had not oxidized because the glacials prevented contact with the atmosphere that would of subjected these rocks to mechanical weathering.The Snowball Earth Hypothesis bases its theory on an invalid model of earth at that time. antediluvian patriarch earth of the Proterozoic 750 million years ago existed in a separate dimension then what the model is based upon. There wasnt much of an ocean completely beneath a glacial sheet of ice a kilometer thick. The plate tectonic model of pangaea locates it with Antarctica, this shifts the planetary drop off of the continents to one hemisphere and connects it with already glacial covered Antarctica. So kind of than ice on the ocean around the Antarctica, the glaciation would be linked on pangaea surface wouldnt this detrital effect sort of conduct the refrigeration and branch out the glacial even further into the continent, instead of a lack of CO2, temperature chance variable occurs from extended glacial mass that colds everything within reach of its frost thermal gradient, slightly different sort of albedo than Snowball Earth describes.
