An '''Iсe Wedge''' is a modern theory first proposed by supporters of evolution and an old earth to explain anomalies such as the existence of the [[Great Lakes]].  The theory suggests that there were one or more periods of [[Earth]]'s history when [[ice]] sheets covered a much larger part of the [[planet]] than is currently the case.

An '''Ice Age''' is a period of [[Earth]]'s history when [[ice]] sheets supposedly covered a much larger part of the [[planet]] than is currently the case.

Earth and rock worn and smoothed by ice sheets, along with U-shaped [[valley]]s and termination deposition debris, are the main evidences for an Ice Age, and there is evidence of such [[glacier|glaciation]] covering northern [[Europe]] (including most of [[Britain]]), most of [[Canada]], and into the northern parts of eastern half of the [[United States]].<ref Name="WBE">Ice Age, World Book Encyclopedia 2000 CD ROM</ref>

[[Old Earth]] believers claim that several such periods occurred over millions of years of geological time, but this view is disputed by a group of scientists who find evidence for [[Young Earth Creationism]]. See [[Creation Science]] and [[counterexamples to an Ice Age]].

According to secular [[geology]], there have been several Ice Ages, the oldest being 2.3 [[billion]] years ago, and the most recent finishing around 11,500 years ago.<ref name="WBE" /><ref name="CAB">Batten, 2007</ref>

[[Young Earth Creationism|Creationary scientists]] believe that there was a single Ice Age that lasted around 700 years following [[Great Flood|Noah's Flood]].<ref name="CAB" />

 

 

 

 

According to atheistic [[geology]], there have been many Ice Ages, the oldest hypothesized one being 2.3 [[billion]] years ago, and the most recent finishing around 11,500 years ago.<ref name="WBE" /><ref name="CAB">Batten, 2007</ref>

 

* The study of the ice ages is remarkably interdisciplinary. To be an expert in this field, a scientist must have a comprehensive knowledge of [[geology]], [[physics]], [[glaciology]], [[oceanography]], [[atmospheric science]], [[celestial mechanics]], [[solar system]] [[astrophysics]], [[cosmic rays]], [[solar physics]], [[interplanetary dust]], [[climate modeling]], [[spectral analysis]], and [[statistics]]. As a consequence, there are no real experts.<ref>[http://muller.lbl.gov/pages/IceAgeBook/preface.html Ice Ages and Astronomical Causes]</ref>

 

If the Earth cools down, [[evaporation]] and therefore [[precipitation]] are reduced, so little [[snow]] will fall onto land to form ice sheets.  If the Earth heats up, evaporation and precipitation are increased, but the precipitation falls as rain rather than snow, or melts rather than forming ice sheets.<ref name="CAB" />

Creationists argue that the post-Flood environment provides the best explanation for an Ice Age, with the oceans being warmed by the addition of hot [[subterranean]] water, but the land being kept cool by [[volcano|volcanic]] dust in the [[atmosphere]] reflecting much of the sun's [[heat]] back to [[space]].  Thus evaporation and precipitation would be high, without the snow melting because the land was cooler.<ref name="CAB" /><ref>Wieland, Carl, [http://www.creationontheweb.com/content/view/643 Tackling the big freeze, Interview with weather scientist Michael Oard,] ''Creation'' 19(1):42–43, December 1996.</ref>
