What is Ice Age? How and when does it occur?

An Ice Age is a period of time, typically about 30 million years but occasionally as long as 300 million years, during which ice sheets cover at least the Earth’s polar areas. Individual Ice Ages have sub-Ice Ages, called glacials (when cold) or interglacials (when warmer) that operate in cycles of 40,000 and 100,000 years.
