There are several ice ages that has taken place here on earth. Recent studies of ice ages have interpreted glacial events by analyzing the oxygen isotope ratio in marine sediments.
- The Ice Age is a very popular timeframe in history. It is known to be a long time of decreasing in the temperature of Earth's surface and atmosphere.
