Snow
Snow is a form of precipitation within the Earth's atmosphere in the form of crystalline water ice, consisting of a multitude of snowflakes that fall from clouds. Since snow is composed of small ice particles, it is a granular material. It has an open and therefore soft structure, unless packed by...

Glacier
A glacier is a large persistent body of ice that forms where the accumulation of snow exceeds its ablation over many years, often centuries. At least 0.1 km² in area and 50 m thick, but often much larger, a glacier slowly deforms and flows due to stresses induced by its weight...

Jacka Glacier
Jacka Glacier is a long glacier which flows northeast from Hayter Peak and terminates in icefalls opposite Vanhoffen Bluff on the north side of Heard Island in the southern Indian Ocean. The glacier appears to be roughly charted on an 1860 sketch map compiled by Captain H.C. Chester, an American...

Icefall
An icefall is a portion of some glaciers characterized by rapid flow and a chaotic crevassed surface. Perhaps the most conspicuous consequence of glacier flow, icefalls occur where the glacier bed steepens and/or narrows...
