Line 10: − During an Ice Age, lowered sea levels due to the water being tied up in glaciers and ice caps would result in [[land bridge]]s in some places where there are now [[ocean]]s and [[strait]]s. − − 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" />
at this point, pretty much the article begins with physical science having its say. Now on to Young earth creationism
An '''Ice Age''', as proposed by secular geology, is period of [[Earth]]'s history when [[ice]] sheets covered a much larger part of the [[planet]] than is currently the case.

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>

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>

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 [[outer space|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>
