PPT-Glaciation What creates glaciers and the process of glaciation (being covered by glaciers)?

Sunlight or lack of Insolation The quantity and intensity of solar radiation upon an object In this case the Earths surface Assuming the output of energy is constant from the sun the rays will be spread over a larger area the nearer you get to the poles. ?”. with Dr. Michael .

GLACIERS OF GLACIERS OF SWEDEN By VALTER SCHYTT 1 2 Abstract The most recent glacier inventory lists a total glacier area for Sweden of 314 square kilometers. The first glaciological were made in 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 .
