Paleo Slide Set: The Ice Ages
This slide show will aid in the quest to understand the cause of the Pleistocene ice ages, an example of how scientists have used different types of evidence to understand earth processes. It traces the history of investigation of the ice ages, from the discovery of glacial erratics and moraines in the 1800s, and the theories of orbital variations in solar radiation, to recent investigations of the glacial-interglacial cycles using evidence found in ice cores and deep sea sediments. This slide set emphasizes how different types of geologic evidence can be used to understand how earth climate has varied in the past. The set includes photos of evidence of glaciers, pictures and graphs from ice cores and marine sediment cores, and pictures illustrating changes in the earths orbit. Each is accompanied by a comprehensive narrative and can be enlarged for better viewing.
