Description of the activity/assignment
What is commonly referred to as the "Ice Age," a time when one-quarter of Earth's land surface was buried by ice, occurred during the Pleistocene Epoch of the Quaternary Period. Pleistocene glaciers profoundly affected landscapes in many parts of the world, including the central United States.
Student materials for this exercise include a Microsoft Excel spreadsheet with data on insolation, hydrogen stable isotopes from glacial ice, and oxygen stable isotopes from deep-sea sediments; an MS Word file student instructions and questions; and an image file with glacial samples. The exercise is divided into three parts.
Part I introduces various types of glacial sediment, maps of moraines, and a general Pleistocene history of Illinois.
In Part II, students work with insolation data at the top of the atmosphere at 65°N, creating a chart and comparing it with the traditional glacial episodes.
Part III involves stable isotope records of δD from the Vostok ice core in Antarctica and δ18O from deep-sea sediment cores. Students graph both records, compare one to the other, and then compare them to the insolation curve from Part II.
