Major Concepts. The gradual cooling evident in the mid to late Cenozoic reached a critical threshold which triggered extensive . glaciation. around 1.8 Ma. . 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 Ice. . Once . glacial ice exceeds a thickness of about 150 feet, the weight of the overlying ice causes . the . base of . the glacier . to become plastic and flow like a very viscous liquid. While the bottom ice responds as a plastic solid, the surface ice is very brittle. However, from the surface down to the top of the plastic portion of the glacier, the ice experiences a decrease in .
