An '''Ice Age''' is a hypothetical period of time during which the [[earth]]'s average [[temperature]] dropps so much that [[glacier]]s extend into what we think of as [[temperate]] zones and that sea levels recede due to the loss of water to the ice.

The theory of an Ice Age is relatively new in the history of science.  The theory developed as humanistic scientists sought an explanation for evidence that conflicts with their view that Earth must be over a billion years old, and their view that no [[Flood]] occurred.  The Ice Age theory seeks to explain the heavily eroded and rounded mountains of the northern [[Appalachian]] chain and large islands such as [[Cape Cod]] and [[Long Island]].
