WebDec 13, 2024 · Glaciers can move by internal plastic deformation, where the glacier's weight causes its lower levels to move and flow differently than the upper layers. They can also move by basal slipping... An ice core is a vertical column through a glacier, sampling the layers that formed through an annual cycle of snowfall and melt. As snow accumulates, each layer presses on lower layers, making them denser until they turn into firn. Firn is not dense enough to prevent air from escaping; but at a density of about 830 kg/m it turns to ice, and the air within is sealed into bubbles that capture t…
