An Ice Age is a period of Earth's history when ice sheets 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 valleys are the main evidence for an Ice Age, and there is evidence of such glaciation covering northern Europe (including most of Britain), most of Canada, and into the northern parts of eastern half of the United States.[1]

During an Ice Age, lowered sea levels would result in land bridges in some places where there are now oceans and straits.

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.[1][2] Creationary scientists believe that there was a single Ice Age that lasted around 700 years following Noah's Flood.[2]

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.[2]

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 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.[2][3]

The Bible perhaps mentions this Ice Age:

From whose womb comes the ice?
    Who gives birth to the frost from the heavens
when the waters become hard as stone,
    when the surface of the deep is frozen?
Job 38:28-29 (NIV)
