Ice Age

 

a relatively long stage in the geological history of the earth during which, against the background of a general relative cooling of the climate, there was repeated alternation of very cold intervals of time (glacials), when extensive continental glaciation occurred, and intervals of time with a warmer climate (interglacials), when a significant part of the continental ice melted. Ice ages have been established in the Lower Proterozoic in North America; in the Upper Riphean in Africa and Australia; in the Wend in Europe, Asia, and North America; in the Ordovician of Africa; and at the end of the Carboniferous and the beginning of the Permian on the continent of Gondwana. The ice age of the Pleistocene has been studied most.
