What is glaciation? Glaciation is the study of ice and its impact on the environment. The Ice Age in Britain lasted from about one million years ago to about 20 000 years ago. During that time the northern and eastern parts of the British Isles were covered in ice. Some places were under 3km of ice.
A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and seracs, as it slowly flows and deforms under stresses induced by its weight.

19 paź 2023 · Glaciers are large bodies of ice that move over Earth’s surface. A glacier is formed as snow accumulates over time and turns to ice, a process that can take more than a hundred years. Once a glacier has formed, it moves very slowly, at a rate of years, or even decades; some glaciers are frozen solid and do not move at all.

Glaciers are accumulations of snow transformed into solid ice. Important questions of glacial geology concern the climatic controls that influence the occurrence of glaciers, the processes by which snow is transformed into ice, and the mechanism of the flow of ice within glaciers. Other important….
