Using the period of peak of temperature associated with an interglacial period for reference, what was the approximate time interval between major periods of glaciation over the last 450,000 years?

The question is based on Figure 24-5, showing variations in CO2 and temperature anomalies in Antarctica going back 800,000 years. This temperature record shows the major glacial (cold) and interglacial (warm) periods of the later Pleistocene Epoch (2.58 million to 11,700 years ago).
What will be an ideal response?


About 100,000 years.
