Abstract. The ‘glacial theory’ championed by Louis Agassiz in the 19th century saw the beginning of the geological community’s partial acceptance of the concept of multiple and more extensive glaciations. Formal recognition of multiple glaciations came in 1909 with Penck and Brückner’s Alpine model. Since then, research on the Earth ...
25 paź 2018 · Glaciation: A Very Short Introduction offers an overview of glaciers and ice sheets as systems, considering the role of geomorphology and sedimentology in studying them, and their impacts on our planet in terms of erosional and depositional processes.

Introduction. A glacier is defined is a mass of ice on land surface that moves under its own weight. It forms when snow accumulation exceeds ablation in a typical year. Snowfall, wind drift, avalanches, freezing rain, and meltwater in the snow pack cause accumulation.
A glacier is an extended mass of ice formed from snow falling and accumulating over a long period of time; glaciers move very slowly, either descending from high mountains, as in valley glaciers, or moving outward from centers of accumulation, as in continental glaciers.
