Chapter 12 Bao Mario Ariel amp Keiyro 121 Project CLIMAP CLIMAP Climate Mapping and Predictions Project began in early 1970s First map of iceage Earth released 1976 121 First CLIMAP Map. Glacial Deposits, formed a Work Group on Glacial Tectonics(WGGT) in 1987. Dr. J. Aber served as the overall coordinatorfor North America. By 1993 Aber had compiled an extensivebibliography consisti January 21, 2011. . Glaciers act as agents of erosion and deposition to help to create unique landforms which you will study in this unit. Glacier. : A large mass of ice resting on land or floating as an ice shelf in the sea adjacent to land. Glacial Erosion. As glaciers travel over land, glacial ice can erode the underlying bedrock.. This erosion can happen by:. Plucking. A. brasion. Plucking. This occurs when melt water at the base of the glacier freezes in cracks and fractures the underlying bedrock.. GEOL 2110. The Pleistocene Epoch. The Ice Age. Major Concepts. The gradual cooling evident in the mid to late Cenozoic reached a critical threshold which triggered extensive . glaciation. around 1.8 Ma. . Chapter 3: Changing Climates. The Big Freeze. A cooling trend began in the Cretaceous Period and continued throughout the Tertiary Period. By the end of the Tertiary Period (1.7 . mya. ) the climate became so cold that snow began o accumulate year after year in the Polar regions.
